The NanoPi M4B is a minor revision of the original M4.
The differences against the original Nanopi M4 that are common with the
other M4V2 revision include:
- microphone header removed
- power button added
- recovery button added
Additional changes specific to the M4B:
- USB 3.0 hub removed; board now has 2x USB 3.0 type-A ports and 2x
USB 2.0 ports
- ADB toggle switch added; this changes the top USB 3.0 host port to
a peripheral port
- Type-C port no longer supports data or PD
- WiFi/Bluetooth combo chip switched to AP6256, which supports BT 5.0
but only 1T1R (down from 2T2R) for WiFi
