# Tag Connect

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

* STLINK-V3MINI $11 everywhere

* TC2030-CLIP-3PACK

The image above is a bit confusing https://github.com/rusefi/hw_microRusEfi/issues/234

* Three more important wires are: GND (black on TC2030)
* Three more important wires are: 13-swdio (yellow on TC2030)
* Three more important wires are: 14-swclk (red on TC2030)
* nice to have +3.3v pin 1(blue on TC2030)
* nice to have RESET pin (green on TC2030)

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