Pin 1 of the MCU is on the corner near the crystal. On the unpopulated 2mm pitch debug header near the MCU, we're calling pin 4 the pin nearest the crystal, and pin 1 the farthest.
| Header Pin | MCU Pin | Function |
|---|---|---|
| 1 | 46 | PA13/JTMS-SWDIO |
| 2 | 47 | VSS_2 (GND) |
| 3 | 48 | VDD_2 (+3.3V) |
| 4 | 49 | PA14/JTCK-SWCLK |
