4.2 BR-DEV-LE5.0 Development Board
The BR-DEV-LE5.0 Development Board (Dev Board) provides users with a ready to use out of the box development
system that’s easily customizable to fit the user’s needs. LEDs are connected to PIOs 2, 5, 7, and 8, and switches are
connected to PIOs 3, 4, 6, 14, and RESET. In addition, all the PIOs are accessible on the I/O bank header. The Dev
Board has one USB connector to the USB CDC ACM virtual serial port on BR-LE5.0-S1 modules. It also has two
programming/debugging headers to support both Cortex Debug and Cortex Debug+ETM.
The module on the Dev Board can be powered by USB, 3.0V CR2032 battery, or an external supply. For powering by
USB set the power switch to the USB position and connect the USB port to a host or other USB power source. For
powering by battery set the power switch to the BATT position and insert a CR2032 into the battery holder on the bottom
of the board. To power through an external supply (1.7-3.6V), set the switch to the VDD position. An external supply can
be connected to the GND and VDD signals on the I/O bank headers.
