Step 5. Connect the load on the output connector (see Section 1.1.2 Power section ).
Step 6. Reset the example sequence by pushing the black button on the STM32 Nucleo board.

1.5 Multiple board configuration
It is also possible to evaluate an eight channel digital output module by stacking four X-NUCLEO-OUT04A1 with
shared or independent supply rail and independent loads.
In this case, the four expansion boards (board 0, 1, 2, 3 as shown in the table below) must be properly configured:
for board 1, 2 and 3, it is necessary to unsolder four resistors for each board from the default position and solder
them back in the alternate positions according to the following table.
Table 3. Configuration of a stack of four expansion boards
Board no. IN1 IN2 FLT1 FLT2
Board 0 R101 R102 R103 R104
Board 1 R131 R132 R133 R134
Board 2 R111 R112 R113 R114
Board 3 R121 R122 R123 R124
Important:
When using Board 2 and Board 3, two jumpers must close the morpho connectors pins in the
STM32 Nucleo board:
• CN7.35-36 closed
• CN10.25-26 closed
