+* STM32F042C6T6
 * Two MOSFET drivers fans
-* One big MOSFET driver for a hotend heater
+* One bigger MOSFET driver for a hotend heater
 * Thermistor input
 * One endstop
+* CAN bus
 
 Main power is 12-24V
 
-Communication with host is done via micro USB, small electronics is powered though that
+
+The CAN Bus is not terminated, instead it uses 4 wires, termination should be done at other end.
+
+It uses an external 5V switch regulator. 
 
 All done in KiCad
 
 Possible issues:
+
 * Is the cooling for the TMC2209 adequate?
 
 
+Change ideas:
+
+Is the endstop useful? Better with a servo output?
+
+
+Use an STM32F103 instead? Pinout is the same. F042 has klipper CAN support. Porting the klipper code to F103 should not be that hard.
