This repository contains a PCB design for a WIFI JTAG probe using the ESP-12 ESP8266 module. The probe is designed to be compatible with blackmagic-espidf. The JTAG signals (+UART) are connected as follows to ESP8266 GPIOs:
| JTAG Signal | GPIO |
|---|---|
| TXD | 1 |
| RXD | 3 |
| TMS/SWDIO | 4 |
| TCK/SWCLK | 5 |
| SRST | 12 |
| TDI | 13 |
| TDO | 14 |
In addition, the 10-pin connector provides 5V and 3.3V supplies. The PCB is provided with power via USB and 3.3V is provided by a cheap 1117 linear regulator.
