esp8266-jtag

Breakout board for ESP8266 ESP-12E module, with JTAG support.

I've built a few of these and they work well. Getting JTAG to work is... not easy. The JTAG pins aren't available during reset, and often aren't available at all unless you configure them in your code. Ping me if you're having trouble and I'll try to document better!
