Compatibility List
The PinePhone has 6 "pogo pins" on the back allowing for custom hardware
extensions such as wireless charging or an IR blaster. The pogo pins provide
access to an interrupt line, power input to charge the battery, 3.3v power
source, and an I2C interface.
A step/stl/stp (3D model) file for the back cover is freely available for
creating custom cases that interface with the pogo pins.

UART serial connector for PineBook and PinePhone
The PinePhone has a serial port in the headphone connector, it's activated by
the 6th contact on the dipswitch. If the switch is on then the headphone
connector is in audio mode, if it's off then it's in UART mode. This uart serial
connection can also be used for communication with other devices from the
PinePhone.
The uart is 115200n8
The pinout for the serial connector on the tablet side is:
• Tip: RX
• Ring: TX
• Sleeve: GND
The serial connection is 3.3V
You can also buy the debug cable from
PINE64 Store The store cable uses a 4 ring
plug, as seen in the PDF, but a 3 ring plug works just as well. That cable uses
a CH340 chipset based serial to USB converter, but any 3.3v serial connection
can be used.
