+# Klipper Toolboard
+A very small 3D printer board for use on a toolhead.
+
+Features: 
+* TMC2209 driver
+* ATmega168
+* Two MOSFET drivers fans
+* One big MOSFET driver for a hotend heater
+* Thermistor input
+* Servo connector
+
+
+It should be fed from the mainboard with 12-24V, 3.3V or 5V, GND, UART RX and UART TX. 
+
+Possible issues:
+* Is the cooling for the TMC2209 adequate?
+* How well will the UART cmos/ttl level survive? Noise?
+* Does it work
