I have some problem with TX2.My carrier is B04 with DC12V for power supply.But TX2 can’t power on in this case.Who can tell me why.
Hi, do you mean NV dev kit or your custom board? Did you try other power supply?
It is NV dev kit.TX1 on this carrier can power on and work but TX2 can’t.Also TX2 can power on and work on DC17V to DC19V.
Did you measure the real voltage level of input on carrier board board? Did you probe the voltage drop during power on? Basically it can work in range of 5.5V ~ 19.6V
