Authentic User Feedback

🔧 DIY Electronics Enthusiast Reviews

⭐⭐⭐⭐⭐ Alex Turner - Maker & Robotics Hobbyist
"I’ve been using the Factory Pro Micro USB-C for custom mechanical keyboards and small robotics builds. The ATmega32U4 chip works flawlessly with Arduino IDE, and the USB-C port is a game-changer—no more fiddling with micro-USB cables. Soldered in some Hall effect sensors for a project, and the 2x10-pin headers made expansion a breeze."

🎛️ IoT Developer Reviews

⭐⭐⭐⭐⭐ Priya Mehta - Embedded Systems Engineer
"Chose the Advanced Model for a smart home sensor array project. The 64KB flash memory and 20MHz clock speed gave me enough headroom for OTA updates and real-time data logging. USB-C made firmware uploads consistent, and the FR4 board has held up well under repeated prototyping cycles."

🖱️ Keyboard Customization Enthusiast Reviews

⭐⭐⭐⭐☆ Jordan Lee - Mechanical Keyboard Builder
"Used this board to convert an old TKL case into a fully programmable keyboard. The native USB HID support eliminated latency issues I had with other clones. Pinout is clearly labeled, which saved me time. Only reason it's not 5 stars is the lack of onboard EEPROM for multiple profiles—but that’s expected at this price."
