Burner socket purchase link:

TSSOP-20 programming socket (plastic body width 4.4mm): https://item.taobao.com/item.htm?id=520002622038

MSOP-10 with board programming seat (plastic body width 3mm): https://item.taobao.com/item.htm?id=524933101915

SOP-16 narrow body programming socket (plastic body width 3.9mm): https://item.taobao.com/item.htm?id=45616378399

Since the MSOP-10 programming socket is relatively expensive and not commonly used, it is not recommended to be soldered directly on this simple downloader.

It is recommended to weld two headers on a simple downloader (the spacing between headers is 10mm) and buy a socket with a header adapter plate.
