Hi all.
I need some help with the Axe210 board please?
I bought the Xbee starter kit (2x Axe210 boards + Xbee modules, 1 x Picaxe 18X and 2 x MAX3232 chips).
All worked fine during testing and setup as in the Picaxe and XBee tutorial with Board A (Max 3232) and Board B (Picaxe)
Today I powered up Board A and it worked fine, I can communicate with it via the serial cable and the XBee status LED's are flashing.
I powered up Board B but there's no XBee LED's flashing. I connected the serial cable to Board B and I downloaded a program to the Picaxe, but there's no communication with the XBee.
I swapped chips between boards and all chips work fine on Board A, but neither XBee works on Board B.
I removed all chips from Board B and checked the voltages on the XBee pins and got 3.5 volts on both the 3V pin and the GND pin. On Board A I get 3V and 0.3mV respectively.
So what could be wrong with Board B? Have I fried the voltage regulators? They're the later MCP1702 chips. I'm using the 4.5 volt battery packs supplied with the kit.
Any help would be appreciated.
Thanks
