“When we went to the market with only a motor, the customers asked us, ‘Okay, where is the ESC?’” narrated Karna Raj, Co-Founder & Chief Technology Officer of Vector Technics. Eventually, the company added BLDC motors, propellers, Electronic Speed Controllers (ESCs), Power Distribution Boards (PDBs), and DC-DC converters to its catalog. “We just listened to the customer…
Understanding Vicharak starts with the Von Neumann Bottleneck. To those unfamiliar, in short, it’s a fast computer wasting time waiting on memory delivery. At a slightly technical level, dated implementations of the Von Neumann architecture involved moving data between the processor and memory through a single bus, which forced instructions and data to compete for bandwidth. This meant that…
A robotic arm is one of those classic projects that almost every electronics enthusiast tries at some point. It’s a perfect mix of mechanics, electronics, and hands-on creativity and building one teaches you more than any textbook ever could. When most people think of robotic arms, they picture the big, ultra-precise industrial robotic arm machines found in factories…
Airbound is a drone startup on a mission to make logistics virtually invisible. What the company imagines is an internet for postal codes instead of IP addresses. We explored their facility to understand what happens behind the scenes, and through this article, I'll try to piece together how they're engineering their way to that reality.

Recently, DigiKey officially launched its Indian subsidiary, named Digi-Key Electronics & Automation Trading Private Limited, incorporating its existing Global Capability Center (GCC) in Bengaluru. “We always considered this location to be a very strategic hub for DigiKey,” stressed the company’s CIO, Ramesh Babu, in an exclusive interview with CircuitDigest. He’s been with the company for…
Over the years, I’ve collected a few Raspberry Pi boards, my trusty Pi 4 and even an older Pi 3 that was gathering dust in a drawer. Instead of letting them sit unused, I decided to give them a new life by turning them into something surprisingly practical: a Raspberry Pi WiFi router with built-in ad-blocking capabilities.
With the…
If you’ve tinkered with Raspberry Pi boards for a while, you probably know the default choice: Raspberry Pi OS. It’s lightweight, optimised, and works flawlessly for most DIY projects. But what if you could install Windows 11 on Raspberry Pi? That's exactly what I accomplished on my Raspberry Pi 4 and later on the Pi 5 and Pi 3.
That’s exactly what I set out…
STMicroelectronics showcased what their STM32MP2 microprocessors are capable of at their electronica India 2025 booth. Visitors could play a game of tic-tac-toe with a robotic arm. The demonstration clearly exhibited how the chips allow for AI-powered robotic applications without cloud connectivity. The robot could recognize colors and positions, and take strategic decisions based on that. "So…
You’re hunting through component distributors trying to find that perfect microcontroller for your project. Let’s say you need three SPI controllers, I²C interfaces, and some specific ADC configuration. You go on to find something that has just the right number of SPI controllers, but before you celebrate, you notice it lacks I²C compatibility. It does not stop there; you rummage again, find…
ROHM Semiconductor was among the key players that exhibited at electronica India 2025. The company’s Group Manager - Technical Centre, Balaji Karthic, while giving us an overview, called attention to their near two decades of research and development in SiC (silicon carbide) that led to their fifth-generation devices. The company’s offerings go from wafers to discretes to modules, and their…
Flying a drone manually requires constant attention to throttle control. One moment of distraction and your drone either crashes into the ground or flies away into the ceiling. If you're building your LiteWing from scratch, check out our detailed step-by-step LiteWing assembly guide to get started with your build. This is where Drone height hold mode becomes a…
During electronica India and productronica India 2025, CircuitDigest sat down with Kevin Hess, Senior Vice President of Marketing at Mouser. The discussion covered his 35-year career at Mouser, shifts in electronics marketing, and the company’s outlook for India. The veteran reflected on the days of catalog-based sales and how he witnessed it transform into the…
