The Olimex debugger needs a USB type B cable which might not be that common anymore, just a heads up.
## JTAG connectors
There are two Cortex-M 10pin (2×5, 1.27mm pitch) JTAG interfaces on the AI-deck so that both the GAP8 and the ESP32 can be programmed and debugged easily. They are edge mounted on the PCB to save height. The GAP8 JTAG is located on the left side and the ESP32 JTAG to the right when viewing the board from the top and camera front. Note that pin-1 is located to the left, marked with a 1 on the bottom side of the board.

Use a 2×5 pin 1.27mm (0.05“) flat cable together with our [debug adapter](https://www.bitcraze.io/debug-adapter-kit) or e.g. an adapter such as the [Olimex ARM-JTAG-20-10](https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10), is needed to connect the debugger and the AI-deck. The ESP-PROG normally comes with the right cable.
