This schematic is designed to be as minimalist as possible but a great place to start.&#x20;

It includes&#x20;

* x2 Standard JST-GH 4 Pin connectors providing Power and Signal in.&#x20;
* A Solder Pad Jumper to enable the 120 ohm Termination Resistor
* Every Edge Pin broken out to 2.54mm headers
* 20x20mm & 30.5x30.5mm M3 Mounting Holes

This schematic is designed to utilise the [Mavlink bridge available to ESP devices ](https://ardupilot.org/copter/docs/common-esp8266-telemetry.html)and simply connects the UART from the CAN Node to the UART on the ESP Device. Flash the ESP before permanently soldering!

It includes&#x20;

* x2 Standard JST-GH 4 Pin connectors providing Power and Signal in.&#x20;
* A Solder Pad Jumper to enable the 120 ohm Termination Resistor
* Headers for the Wemos D1 Mini Pro v4
