Badge
Badge is an open source ESP32 PCB design by atopile: a 4-layer, 56.3 × 39 mm board with 239 components (23 distinct parts). It is built around the 532610271, ICS-43434, ESP32-C3-MINI-1-N4, BQ25185DLHR and more. Filed under wearables and displays & leds and power & battery.
Design circuit boards with code! ✨ Get software-like design reuse 🚀, validation, version control and collaboration in hardware; starting with electronics ⚡️
Write hardware like software. atopile is a language, compiler, and toolchain for electronics—declarative .ato files, deep validation, and layout that works natively with KiCad.
- Reusable modules instead of starting from scratch every time - Capture intent with equations directly in your design - Automatic parametric picking of discrete components
The easiest way is via the editor extension—it installs and manages ato for you:
