Board description

2.2.1

Hardware configuration

2.2.2

Power supply

The board does not contain a power supply. VCC = 3.3 V DC supply should be provided

externally, by J7 connector. If the board is interfaced to PC by the STEVAL-IPE023V1

isolated dongle, it provides the board with supply.

2.2.3

Enable and reset

The STPM3x enable pin should be shorted to VCC by keeping J4 jumper in EN position. To

reset the device, this jumper has to be in OFF position (GND).
