* on-module NPU (optional)
* SD card (on a baseboard) via edge connector
* 100mbps Ethernet (on a baseboard) via edge connector
* MIPI-DSI (on a baseboard) via edge connector
* Audio (on a baseboard) via edge connector
- 1x SPDIF
- 1x 8-channel I2S/TDM
- 1x 2-channel I2S/TDM
- 1x 8-channel PDM
* USB (on a baseboard) via edge connector
- 1x USB 2.0 OTG
