The Lichee Pi Zero board has a "dock board" which needs to be soldered with the 1.27mm stamp holes on a Lichee Pi Zero board. It features: - Onboard MIC and headphone jack (not supported yet) - Ethernet port (not supported yet) - An extra MicroSD slot connected to MMC1 controller - four keys connected to the LRADC. As it needs to be soldered with the main board to use, add a stand-alone device tree for it.
