This board is supposed to replace the Raspberry Pi Zero 2W in the bloop box with a cheaper alternative, using an ESP32-C5.
It will support all functions of the bloop box and can be used as a drop-in-replacement for the Raspi. In addition, due to the capabilities of the ESP32-C5 this will have support for 5GHz WiFi.
