So far, these are my personal observations of the PinePhone Keyboard. The name of that will change -- oops.
This Keyboard Case is a case for the PinePhone and PinePhone Pro. As the name implies, it adds a keyboard to the phones. It also has a 6000 mAh battery that essentially tripples¹ the phone's 3000 mAh battery life.
¹ See Charging Information for more information.
Connectivity
The Keyboard Case has six pins that connect it to the PinePhone or PinePhone Pro.
INT SDA SCL VBUS VBAT GND
The SDA and SCL pins belong to the I2C Bus.
VBUS connects to the charging line. See Charging Information for more information.
The VBAT pin connects to the battery. This powers the keyboard if it is out of power.
INT is a pin that's used for interrupts. In this case, it is used so the phone can request key presses from the keyboard.
Charging Information
The output of the IP5209 is connected to the VBUS pin.
