Important Notes JP1 : close in INT position for use with PractiSPIN ST7 board C6, C7 : recommended change to 5.6 nF for safe Overcurrent protection R3, R4 : recommended change to 100 k for safe Overcurrent protection R5, R6 : recommended change to 100 k if EN pins are driven from the CN5 connector (for example with PractiSPIN ST7 board), for safe Overcurrent protection R17, R21 : set the maximum current obtainable through PractiSPIN (see PractiSPIN documentation) R2 : recommended change to adequate value (depending on supply voltage) to obtain 5V across D3 JP2, JP3 : close for safe Overcurrent protection JP4, JP5 : close for use with PractiSPIN ST7 board
