I did some tests and found that the Rephone itself draws 3.724mA while in the 'OFF' state and 4.256mA if it's...

I believe I read somewhere that the serial monitor actually works on the alternate COM port (i.e. you load up code on COM3, use the serial monitor on COM4) but I can't seem to get it to work myself. You'll also have to match the baud rates (if it's 115200 baud in your code, you'll have to match the ...

Hey I noticed something that you might be running into. Once plugged into USB, and even though I power it up with the power button and the LED turns green, most of the time the Rephone doesn't actually appear in my Device manager. I have to hold the power button down until the LED turns red and then...
