Shift register

A shift register is controlling the status LEDs and the relay output, the pinout for it is the following:

QARelay

QCRGB Blue
QDRGB Green
QERGB Red
QFnc
QGnc
QHnc

The Out 1 status LED and the relay are on the same output. From what I've seen the board looks like it's being used for the Shelly Pro 1, Pro 2, Pro 1PM, and Pro 2PM. But I can't comfirm it. There are all the spaces needed for all device variants.
