Programming and testing is accomplished via a 10 pin card-edge connector. The pinout of this connector and mapping to a standard AVR 6-pin ISP is given in the table below.
| Pin | Name | Notes | ISP |
| 1 | 3.3V | Regulator output | 2 |
| 2 | TxD | UART TX output | |
| 3 | RxD | UART RX input | |
| 4 | SCK | SPI programming clock | 3 |
| 5 | Reset | CPU Reset | 5 |
| 6 | GND | 6 | |
| 7 | GND | ||
| 8 | BT+ | Battery voltage sense | |
| 9 | MISO | SPI programming data out | 1 |
| 10 | MOSI | SPI programmming data in | 4 |
