ST-LINK Wiring:
To flash to the board, the following pin arrangement is needed on the board:
The pins are arranged next to the chip and can be seen below marked in blue, purple, grey, and white:
Wire Colour | Pin Name on ST-LINK | Pin Name on Breakout Board |
|---|---|---|
Blue | RST | NRST_PILOT |
Purple | SWDIO | SWIO_PILOT |
Grey | SWCLK | SCLK_PILOT |
White | GND | GND |
Green | 3V3 | 3V3 |
Additionally, power is required for the board, either using the USB port on the board, or by connecting the 3v3 pin on the ST-LINK to the green pin seen above. The pin labels for that row of pins can be seen below, the 3V3 pin on the board and ST-LINK should match up.
The board should light up once it has power. Additionally, the ST-LINK will have a red light when powered and a blue flashing light when signals are being sent through it.
