An unused 6-pin connector on the MK4S WiFi adapter
There is an undocumented 6-pin Molex CLIK-Mate connector (J2) on the back side of the new Wi-Fi adapter board (FDM-MK4-WiFi). Unfortunately, Prusa no longer provides schematics for their boards (which I would expect from an open-source printer...) and I can't find any information about that connector and how can it be used. Does anyone know if that connector is directly connected to the main I2C bus, allowing us to connect a GPIO "Hackerboard" module (FDM-MK4-GPIO) instead of using the internal I2C port on the xBuddy board? Or is that connector linked to some unused GPIO pins on the ESP-WROOM-02D ESP8266EX-based module on that new Wi-Fi adapter?

Solved: it is used to connect the accelerometer, as described here: https://help.prusa3d.com/article/accelerometer-mk4-s-mk3-9-s_729349
