Left Qualcomm, no customers for two years, built an 11,800 CR company. 1. After completing his master's and PhD in Electrical Engineering from Stanford University, Avneesh Agrawal joined Qualcomm. He led the semiconductor and mobile communications space there for a decade and got the big news. 👇🏻 2. He became the President of Qualcomm India and South Asia. Over four years, he was granted over 200 US patents for his work. During this time, he noticed something. 🤔 3. India faced 4,64,674 road accidents and 1.5 lakh people lost their lives. He believed that computer vision and AI could change driver safety by making roads safer through real-time intelligence. After 15 years, He left his top job. ✅ 4. He started a company with his colleague, Julian, to solve the road safety problem in Bangalore. In August 2015, Netradyne was born. 🚀 5. The idea was simple ⏩ Build a camera-first, vision-driven fleet safety solution with on-device (edge) AI. The flagship product - Driver. i, a rugged multi-lens dashcam that analysed 100% of drive time to identify risky and positive driving behaviours. He thought he had it, but he did not. 👇🏻 6. Low latency for in-cab coaching, building training data pipelines was a challenge. Moreover, convincing fleet operators to try a camera that watched drivers was another. He had to find answers or else Netradyne would not lift off. 🤔 7. He focused on anonymised analytics and Driver training programs to ensure in-cab positive reinforcement for good driving. Moreover, he split the team between the US and India to speed model training and hardware design. By 2016, it raised 108 CR led by Reliance. 💰 8. On 24th March 2017, Netradyne finally had its first commercial customer. It worked with Load One to make their drivers the safest and best-trained drivers on the road. And then customers kept coming - Stewart Transport, General Motors and Bryan Truck Line. By 2018, it raised 148 CR from Microsoft and Reliance. 💸 9. With funds, Avneesh focused on dynamic 3D/HD mapping and packaged underwriting data for insurance companies. By 2021, it had grown to support over 1000 fleets, including Titan Freight Systems and Ace Endico and crossed 1 billion driving miles. In 2021, it raised 1120 CR from Softbank. 📈 10. As it launched Driver.i one, a professional-grade video telematics device in 2023 and scaled to 18 billion minutes with 3000 customers across US, Canada, Mexico, Germany, UK, Australia, New Zealand, India, the big moment came on 16th January 2025.👇🏻 11. Netradyne raised 778 CR led by Point 72 Ventures at a valuation of 8328 CR. It became the first Indian unicorn of 2025. 🦄 11. Today, Netradyne has clocked over 25 billion minutes of driving data and safeguarded over 125 million drivers with an impeccable 99% accuracy of alerts. 💪 ➡️Avneesh Agarwal left his crores in salary at Qualcomm with no customers for two years to build an 11,800 CR company today. He is a man of true inspiration! 🙏 #startups #india

*** Silent Killer in High-Speed Interface Design *** Every engineer working on PCIe, USB, CSI, DSI, LPDDR, SerDes, or any high-speed interface knows: "Timing closure will keep you Up at night." But here’s the thing—It is not always the big violations that kill a design. These can be found and fixed. The silent killers are the marginal cases: * That one Async Clock Domain Crossing that looked fine… until Silicon. * That Power mode Transition that only happens under rare Conditions. * That Corner case in Equalization that only fails in a specific voltage/temp combo. "These don’t show up in the standard verification flow. You have to hunt them down." What’s your approach to catching these hidden pitfalls?

📺 Ever wondered where PWM or PDM is actually used in real life? Most of us remember learning about modulation techniques like PWM (Pulse Width Modulation) or PDM (Pulse Density Modulation) in our embedded systems classes... ...and then we forgot them. Not because they’re useless, but because no one told us where they really shine. 🎯 One underrated yet daily use-case? Your TV or AC Remote. Yes, seriously. Every time you press a button to change the channel or switch off the AC, you're unknowingly triggering a PWM-based communication. 🔍 So How It Works: Infrared (IR) remotes use modulation techniques like PWM or PDM to encode data into light pulses. ➡️ Each key on your remote corresponds to a unique code ➡️That code is sent using bursts of IR light, modulated with PWM ➡️The receiver decodes the duration and gaps between pulses to figure out the command This is how your TV knows you pressed volume up, not power off. ⚙️ Why PWM? Resistant to noise Easy to implement in hardware Efficient for short-range line-of-sight communication 🤯 You thought PWM was only for motor control? Turns out — it’s literally in your hand, every time you use your remote. 💬 So next time you press a button on your remote… Remember: you’re not just flipping channels. You’re engaging a classic embedded system concept — in action! #EmbeddedSystems #microcontroller #programming #C #Cprogramming #SignalProcessing #TechFacts #Electronics

🔋 The Next Battery Wars: Navigating India’s Multi-Chemistry Future I’m delighted to share that my latest article has been published in Battery Magazine: The Next Battery Wars: LFP vs. LMFP vs. Sodium-Ion vs. Solid-State. Thanks to The Battery Magazine for publishing my thoughts on battery chemistries. Thanks Shweta Kumari for picking it up along with other esteemed members. Pls read the full story at the link. https://lnkd.in/g6-4Y4HS The piece explores how India’s battery ecosystem is evolving beyond a single-chemistry narrative. Instead, we are entering a multi-chemistry era, where adoption will be shaped not by hype but by proven reliability, lifecycle economics, and supply-chain resilience. Key insights: - LFP remains the backbone of commercial deployments—cost-efficient, safe, and scalable for India’s high-temperature operating conditions. - LMFP offers incremental energy density gains, but its adoption will be gradual, driven by manganese availability and compatibility with existing infrastructure. - Sodium-ion is emerging as a promising option for stationary storage and cost-sensitive mobility, thanks to abundant raw materials and supply-chain neutrality. - Solid-state continues to inspire R&D, but commercialization will take time due to cost and manufacturing complexity. At Trontek, we believe the future is not about choosing one chemistry over another—it’s about application-driven optimization. OEMs and energy players will prioritize safety, lifecycle cost, and scalability, while deploying chemistries best suited for specific use cases. India’s journey toward energy independence will be defined by how effectively we balance innovation with practicality. Proven scalability and predictable performance will always outweigh marginal gains.

🧠Interrupts vs Polling in Embedded Systems: ESP32 & STM32 Best Practices When designing real-time embedded systems, one of the most important architectural decisions is: 👉Should you use interrupts or polling? This choice can define your system's latency, power consumption, and scalability-critical factors in IoT development, firmware architecture, and microcontroller design. 🔴Polling in Embedded Systems ✅Easy to implement in firmware ✅Suitable for low-frequency or non-critical tasks ⚠️ Drawback: Consumes CPU cycles, reduces efficiency, and increases power consumption 🔴Interrupts in Embedded Systems ✅Event-driven execution → perfect for real-time responsiveness ✅Widely used in ESP32, STM32, and ARM Cortex-M microcontrollers ✅Critical for UART, SPI, I2C, CAN, and sensor data acquisition ⚠️ Requires careful design: race conditions, interrupt priority, and latency management 🤔My Proven Approach (ESP32 + STM32 Projects): hybrid model in firmware design: 🔹Interrupts high-priority tasks (sensor triggers, data reception, communication protocols) 🔹Polling background processes (system diagnostics, logging, Ul updates) #RaspberryPi #Arduino #EmbeddedSystems #Embedded #loT #ElectronicsEngineering #TechInnovation #ElectronicsProjects #TechEnthusiast #MakersCommunity #STEM #LearningByDoing

We obsess over shaving microamps in firmware while ignoring the real power vampire: power integrity collapse. After debugging three field failures in battery-powered medical devices, I’ve learned the hard way: Your firmware optimizations mean nothing if your power delivery network (PDN) is lying to you. Case Study 1: A "5µA sleep mode" IoT sensor kept dying overnight. Root cause? A 4.7µF ceramic capacitor’s resonant frequency (150MHz) coincided with the DC-DC converter’s switching frequency. Result: 200mA current spikes every 10ms, draining the battery in 6 hours instead of 6 months. Case Study 2: An automotive ECU resetting during cold starts. Issue? Voltage droop (-1.2V below nominal) when the fuel injector fired. The 3.3V rail dipped to 1.8V for 500ns, just enough to corrupt the RTC’s shadow registers. Why We Ignore PDN: Toolchain Blindness: Most embedded IDEs can’t simulate PDN impedance. We optimize code in a vacuum. Component Myopia: We select MCUs for "low power specs" but ignore that 80% of power issues stem from passive components. Frequency Illusion: We assume DC-DC converters "just work" without checking: Control loop stability (phase margin <45° = oscillations) Output capacitor ESR (too low = ringing; too high = ripple) Layout inductance (via stubs adding 2nH = 20mV overshoot) The Fix: PDN-First Design Step 1: Simulate PDN impedance (e.g., Keysight ADS) from DC to 1GHz. Target: <0.1Ω up to 50MHz. Step 2: Use mixed capacitor types: Bulk electrolytics (100µF+) for low-frequency stability X7R ceramics (1-10µF) for mid-frequency decoupling NP0/C0G (100nF) for high-frequency noise (>100MHz) Step 3: Layout rules: Place decoupling caps <3mm from MCU power pins Use 20mil+ power traces (reduce inductance by 40%) Split ground planes? NO. Use solid ground under switching components. The Ugly Truth: Most "low-power" designs fail because we treat power as an electrical problem, not a system-level physics problem. Your firmware’s sleep mode is irrelevant if your PDN is a noise generator. Question: What’s your worst power integrity horror story? Bonus points if it involved a capacitor resonance or ground bounce. #PowerIntegrity #EmbeddedDesign #PDN #EMI #Hardware
