| 12 | GND | Ground | |
| 13 | GND | Ground | |
| 14 | GND | Ground | |
| 18 | PB0 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 19 | PB1 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 20 | PB3 | Input /Output | NC PIN, This pin needs to be dangling and the user does not need to connect(for later extension use) |
| 21 | +3.3V | Input | Power pins for program loading (suspended, no need for user to connect) |
| 22 | SWIM | Input | SWIM pin for program load (dangling, user does not need to connect) |
| 23 | GND | Input | Ground pins for program loading (dangling, no user connection required) |
| 24 | RESET | Input | Reset pins for program loading (dangling, no need for user to connect) |
