USB Debug Adapter
The USB debug adapter is used to provide a USB serial interface -- and power where required -- to various Pumpkin modules, without having to host the USB-to-serial electronics and connector on said module. It can be connected to any Pumpkin module that has a 4-pin FPC serial terminal/debug connector. The I/O level is selectable to 3.3V (default) or 5V. The USB debug adapter can also provide either 3.3V or 5V power to the connected device.
