BTT EBB42 Gen2 1.0 filament sensor pin PA10 pinout schematic

💡 Result:

On the BTT EBB42 GEN2 V1.0, MCU pin PA10 is the I²C SDA line, brought out on the I2C header/connector (with PA9 as SCL). (global.bttwiki.com)

If you’re looking for the dedicated filament/runout (“FIL”) switch input, that’s PA3 (separate from the I²C pins). (global.bttwiki.com)

Citations:

Revert filament_sensor_runout_pin from PA10 back to PA3.

According to the official BTT EBB42 GEN2 V1.0 pinout documentation, PA10 is the I²C SDA (data) line and PA9 is the I²C SCL (clock) line. The dedicated filament runout ("FIL") switch input is on PA3. The current mapping at line 41 (filament_sensor_runout_pin=PA10) is incorrect and would break both I²C communication and filament detection. Change it back to filament_sensor_runout_pin=PA3,.

In `@configuration/boards/btt-ebb42-gen2-10/toolboard-config.cfg` at line 41, The
filament sensor pin is set incorrectly: change the configuration key
filament_sensor_runout_pin from PA10 back to the dedicated FIL input PA3 to
restore proper filament detection and avoid clobbering I²C (PA9/PA10) lines;
locate the filament_sensor_runout_pin entry in the toolboard-config.cfg and
replace the PA10 value with PA3 so the line reads
filament_sensor_runout_pin=PA3, ensuring trailing comma matches surrounding
entries.

filament_sensor_motion_pin=PA9,
