Tag Connect¶

rusEFI likes Tag Connect so many boards have that small TC2030 footprint - microRusEFI, Hellen, Proteus and wideband etc.

• STLINK-V3MINI $11 everywhere
• https://www.tag-connect.com/product/tc2030-ctx-nl-stdc14-for-use-with-stm32-processors-with-stlink-v3 cable (old part number: TC2030-CTX-NL-STDC14)
• TC2030-CLIP-3PACK

Way more ghetto option would be based on TC2030-MCP-NL off eBay with phone jack cut off and wires soldered

Three more important wires are:

• GND (black on TC2030)
• 13-swdio (yellow on TC2030)
• 14-swclk (red on TC2030)

Offtopic: STLINK-V3MINI also works with FTSH-105-01-F-DV-007-K on Proteus
