This is the custom circuit board for Stewy's head. It hosts the ESP32-C3 Super Mini and connects to the HC-SR04 distance sensor and KY-023 joystick via JST-XH headers. Like the base board, it's designed for Stewy V2 and made by PCBWay.

Pick the bare PCB if you want to source and solder everything yourself. The unsoldered version comes with all the components included. Or go with the soldered version if you want it ready to install.
