The Debug Board is designed to bridge the Qualcomm Dragonwing's debug interfaces as well as the system controller (MCU) interfaces. This allows for low-level debugging of the system, providing both hardware-level access and software debugging capabilities.

The Debug Adapter is a small PCB that includes:

• An FTDI serial-to-USB chip for 1.8V to USB translation
• A CMSIS-DAP (aka CMDAP) interface for programming the built-in microcontroller

While not needed for all applications, this board is a useful tool during development to diagnose errors and recover from firmware changes.

Ships with 1x 7-inch 10-pin JTAG ribbon cable
