[Open Source]STlink_V2.1

Refer to Zhihui Jun's ST-Link-Nano (basically copied it)
GitHub - peng-zhihui/ST-Link-Nano: Homemade super mini ST-Link module.
As well as the works of other big guys on the open source platform (the works of other big guys are not listed here, you can search for them yourself).
 
 
 
 
 
 
Do not refer to the BOM table below. The originals are all bought from Taobao.
The M18 firmware is used, and the relevant things will be uploaded in the attachment.
If you also want to make STlink and encounter problems, you can ask me below. I will reply if I encounter them too.
The picture on the cover is not from this version. There is still a small problem on the cover (the silk screen is reversed) and I am too lazy to adjust and reprint it.
 
 
 
1. Regarding the jumper issue,
this board uses two jumper 0Ω resistors to realize interface reuse. When burning firmware for it, you need to short-circuit the following two pins.
After burning the firmware, you need to short-circuit the following two pins.
2. Regarding the upgrade issue,
I recommend using the upgrade tool that comes with the STM32 ST-LINK Utility to upgrade. I have replied to the specific method in the comment area, you can check it out.
3. Regarding the purchase of original parts,
the crystal oscillator uses a 3215 crystal oscillator, which can be found on Taobao.
Other originals are commonly used originals, just look for them yourself.
