What is it?

This is a simple, high-speed DAPLink debug probe designed to program ARM microcontrollers, such as STM32 or NRF52. The probe runs this firmware.

Why did you make it?

I created this because I absolutely love STDC14 connectors! They are compact, support UART, and have level-shifting capabilities—what more could you want? Unfortunately, I couldn’t find any programmers using them, except for the official ones from ST, which are somewhat overpriced and use proprietary firmware.

What makes it special?

• STDC14 connector with UART and level-shifting support.
• IDC2.54 connector with a pinout almost identical to the StlinkV2 (excluding the SWIM pin).
• USB high-speed support.
• Pre-flashed with Daplink firmware available from here
• Schematics is available from the Documentation tab

How to use it?

You should be able to use the Daplinker with anything that supports Daplink probes. OpenOCD and any program based on it would work. Here is an example platformio.ini file to flash the Stm32F446RET6 using Daplinker.

What will I receive?

• 1xDaplinker
• 1x1.27 mm pitch 14 Pin 2x7 Position Flat IDC
