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
