79 open source ESP32 boards
Espressif's Wi-Fi and Bluetooth microcontrollers — bare chips and WROOM/WROVER modules, S2, S3, C3 and C6. Every board here is a public GitHub project with its KiCad files, read for size, layers and parts. Pick one close to your design and simulate its firmware on HardLabs before you build it.
