This guide introduces the FoBE Breakout CMSIS-DAP Lite and how to use it.

Hardware diagram

The following figure illustrates the FoBE Breakout CMSIS-DAP Lite hardware diagram.

FoBE Breakout CMSIS-DAP Lite is a single-sided 25.4mm x 25.4mm (1" x 1") 1.6mm thick PCB with a USB-C female and a set of 12-pin 2.54mm pin header.

Two button for reset and bootloader mode, and a DAP-LED indicates the operating status of the DAP protocol.

Fixing by 4 x 1.6mm Screw holes.

The board provides 12-pin 2.54mm pin header interface, which can be used to connect to the target board. The pinout is as follows:

VCP_TXD	Virtual COM Port Transmit (TX)	Transmits data to the target device.
3V3	Power Output	Provides 3.3V power supply to the target device.
5V	Power Output	Provides 5V power supply to the target device.
GND		Ground
SWRST	Software Reset	Resets the target device via software command.
JTAG_TMS	JTAG Test Mode Select	Control signal for JTAG interface mode selection.
JTAG_TDO	JTAG Test Data Output	Outputs test data from the target device.
JTAG_TDI	JTAG Test Data Input	Inputs test data to the target device.
JTAG_TCK	JTAG Test Clock	Clock signal for JTAG interface operations.
