| Serial | Probably | Need to locate it on the board |
| Charging | Yes | charging via AC in works |
| Wireless | Yes | Realtek 8703as, Driver is still in staging (rt8723bs) |
| Bluetooth | Yes? | Realtek 8703as, Uses rt8723bs driver, seems to work, but not tested much |
| Micro USB | WIP | Only works in otg (with dr_mode = "host" in dts), might need further device tree improvments |
| Keyboard | N/A | Device has no keyboard |

| Accelerometer | Yes? | Memsic 6255, There is a screen rotation sensor, mxc6255 driver can be used for it, but doesn't seem to work very well |
| Proximity sensor | N/A | Not sure if available |
| eMMC | No | Likely dts issues |
| HW accelerated video encode/decode | ? | Should work with Cedrus driver, but not tested |
