- 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 B slot is intended for use with a 5G/LTE module, with USB 2.0 provided alongside a PCIe lane. A SIM card slot may be present on the carrier board.
- The M.2 Key A/E slot is intended for use with a M.2 Ethernet module.
- The M.2 Key M slots are intended for use with a M.2 NVMe SSD. This slot could also be used for a M.2 SATA module and ATA power connectors may be provided on the carrier board for this purpose.

USB 2.0 interfaces
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.
MediaCow Touch 2 "Paris"
MediaCow Touch 2 "Paris" uses all of the USB 2.0 interfaces.

Along with I2C and QSPI, a USB 2.0 link is also included between the SoM and SMEC (SP7021). The USB 2.0 link may be used to emulate a keyboard device.
