DAP-link based on Air103

Overview

Because the USB data cable is not very long, and the data speed is not very fast for USB2.0, I only made equal lengths and did not perform differential wiring. The USB port uses a TYPE-B interface because I think such an interface is more stable and less likely to be damaged. The MCU used by the DAP-LINK downloader is AIR32F103. The performance of this MCU is better than STM32f103. It has a faster download speed. DAP-link is designed using AIR32F103. Hezhou officially provides the latest V2 firmware. This firmware download program is very quick.

For more descriptions of open source, please search the WeChat public account "FunIO" to see more of my open source interesting and practical designs.
At the same time, I also made some boards myself, and the lazy person purchased the link Xianyu search user "I am Hadashi" to purchase.
