Overview
Board that connects an existing access motor to the network. An ESP32-C3 with an external antenna drives MOSFET outputs, reads position sensors and shows status on addressable LEDs; it is powered from the installation through a wide-input buck.
Design challenges solved
- 6 layers in 50 × 50 mm with a solid reference plane for the RF module.
- Wide-input buck and ESD protection on USB-C.
