PCB Design files for pool controller for Connect 10
KiCad design for a Connect 10 compatible pool-bus interface, using the finished Waveshare ESP32-C6 Mini Development Board (ESP32-C6-Zero) plugged into a carrier socket. The board provides a 5 V buck supply and single-wire receive/transmit interface. Firmware is maintained in pool-controller-code.
Revision 15 is a prototype for validation. It adds the 3.3 V RX clamp from issue #3 and changes the TX base resistor to 560 Ω as proposed in issue #4. It retains the existing 80 × 75 mm outline and 1.2 mm thickness.
