I'm doing a bit of reseach on mesh networks, and managed to get my hands on two Carambola2-I modules. After purchasing some usb headers, antennas and AMS1117 power supply modules (4.0-12V to 3.3V) and soldering them onto the Carambola2, I intended to connect to them using a serial connection. Unfortunately, the modules weren't recognized by my PC (netiher windows nor linux found them).
My plan was to enable SSH on the modules using serial, then do the rest of the configuration over SSH. I've verified the power delivery works as intended. I've soldered the +3.3V to pin 51 on the Carambola, the GND connection to pin 46 on the Carambola, and the USB+ and - to pins 20 and 21 respectively.
Is there something I'm missing?
