QB1 Main Board for ESP32 Development Kit

QB1 is a rapid prototyping system for ESPHome and other ESP32 devices. The main components are the main board and the 3D-printable enclosure. Sensors, other peripherals, and mounting equipment can be added using the five cube faces. QB1 supports many common sensors using custom face plates and peripheral boards. For more information, see the GitHub repository.

This is a main board that allows a 30-pin ESP32 development kit to be used as the host in a QB1. For information about components and assembly, see the GitHub directory for this main board.
