'''WARNING: Opening or modifying your nanoBTS will render your warranty void and might affect regulatory approval!''' == nanoBTS 1800 == == PCB photographs == see attachments at the end of this page. === Debug Port === There is a serial port for debugging. This port can be accessed via one of the two TIB RJ45 jacks, but only after a small hardware modification has been made. Please reference the following picture for details. After soldering those two connections, the pin-out of ''TIB out'' is as follows: * Pin 7: PPC UART Tx (3.3V) * Pin 8: PPC UART Rx Tx (3.3V) * Pin 10: Ground You can use any level shifter to get the signal up to true RS323 values, or directly connect something like a FT232. The port runs at 115200 bps, 8N1 There seems to be some kind of serial console on the device, we haven't yet figured out more details. == nanoBTS 900 == FIXME
