Adding a serial port (voids warranty)
This section explains how to attach a serial port to the device. Make sure it refers to our UART howto. For a development board, you can just mention how to find the header with the pins and include a picture, and you can remove the warranty voiding warning.
Device disassembly
If necessary, provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped. If pins do need to be popped, mention the Plastic tool howto.
Locating the UART
Describe how to find the RX,TX,GND signals here, and mention the UART howto.
