DAPLink based on STM32F103C8T6/CBT6

Overview

The small-sized DAPLink, based on STM32F103, has two functions: it can be used directly as a DAPLink; it can transfer the ST-Link on the STM8 and STM32 official development boards here to reduce the size and unify the interface.

Just use the original DAPLink for the firmware. DAPLink official source code: https://github.com/ARMmbed/DAPLink

The board supports the production of a variety of downloaders, so be sure to select the parts you need for soldering. DAPLink uses the circuit diagram of ST-Link V2.1, which you can refer to.

The official development boards of STM32 and STM8 have schematics. Soldering R12 and R13 is suitable for transferring the ST-Link of STM32, and soldering R16 and R17 is suitable for transferring the ST-Link of STM8.

The attachment contains the firmware compiled by myself. If you find it difficult to compile the official source code, you can directly use the firmware in the attachment.

BB-black has not been shipped yet...
This morning I saw 36 people bought it on TB, is it too few people? I watched getting started recently, and there is an example of BB-black on the python platform in the tutorial.
