HM-11 Bluetooth Module

Haha true dat!

By the way I actually got it working! I had to use the default 115200 baud to send AT commands to change the baud to a lower baud (like 57600) and then it would respond properly. It may be that the pinouts you've been looking at are all confused and swapped from different boards, etc. Check out my Reflowduino project using the JDY-10 (actually seems to be the JDY-08 from other pictures and user docs, who knows, who cares, I finally got it to work lol).
