Member: 348680 Status: Offline Thanks Meter: 1,273 | check ( with a multimeter ) if you have the correct voltage at F-Bus Battery contacts.... or if using an Unifbus, between red an black clips ( normal values are close to USB Voltage ). And the IC that switches the VBAT is the U3 ( LM1950T ) ( or CS8240 or LM3526H in the newest Box HW rev. ) not the LM3940IS ( it is the 3.3V voltaje reg for the AT32UC3A1512 ) . BR |
