SOM_HSIO_
The HSIO connections on the Intel N100/N305 are mostly used for providing PCIe lanes with the only two being used for other purposes are HSIO0 and HSIO1.
| Port | Purpose | PCIe Device | PCIe Controller |
|---|---|---|---|
| HSIO 0 | Ext. USB 3 | N/A | Controller #1 |
| HSIO 1 | Ext. USB 3 | N/A | Controller #1 |
| HSIO 2 | Reserved | N/A | Controller #1 |
| HSIO 3 | Reserved | N/A | Controller #1 |
| HSIO 6 | M.2 Key E | 1 | Controller #2 |
| HSIO 8 | M.2 Key M | 2 | Controller #3 |
| HSIO 9 | M.2 Key M | 2 | Controller #3 |
| HSIO 10 | M.2 Key M | 2 | Controller #3 |
| HSIO 11 | M.2 Key M | 2 | Controller #3 |
- The first two HSIO lanes are used as USB 3.2 connected to the two USB Type-C ports.
- The M.2 Key E slot is intended for use with a Wi-Fi/BT module, with USB 2.0 provided alongside a PCIe lane.
- The M.2 Key M slots are intended for use with a M.2 NVMe storage module. This slot could also be used for a M.2 SATA module.

SOM_USB2_
The LattePanda Mu SoM exposes eight USB 2.0 interfaces.
Since USB2 interfaces 1, 2, 5 and 6 are able to be assigned to USB Type-C (TCP) ports, 5 and 6 are used for the USB Type-C ports on both versions of MediaCow Touch 2.
Since USB 3.0 connectors have both USB 2 and USB 3 links, USB 2.0 interfaces 1 and 2 are used for the USB 3.2 Type-A ports on both versions of MediaCow Touch 2.
