Daughterboard interface

The main feature of the motherboard is the capability to control an external board,

connected to the J4 and J5 connectors (L in Figure 2). Table 1 shows which pins of the

microcontroller are connected to the daughterboard.

Some of the lines are connected also to a row of test points (M).

The STM32L is preprogrammed with a DFU firmware that allows the downloading of a firmware image without

the use of a programmer. If an user accidentally erases DFU firmware, he can reprogram it through STLink

using the hex image DFU_Bootloader.hex available on BlueNRG-MS DK SW package, firmware folder.
