Are you looking to buy an LDO Toolhead PCB in Australia? For use in conjuction with the breakout board and Toolhead Cable by LDO The Toolhead PCB The toolhead PCB is based on hartk's toolhead PCB design. The main purpose of the toolhead PCB is to combine all the signals and wires (e.g. thermistors, fans, hotend) on the toolhead PCB into a single cable. Compared to the orignal hartk design, the LDO PCB has a few minor differences: The hotend cartridge connector is screw terminal instead of a microfit 3 connector. The onboard thermistors use NTC10K thermistor, more info here. Apart from the above mentioned differences our PCB has the same shape and mounting hole positions, and the 14 pin microfit pinout is 100% compatible with the original hartk PCB. Port Descriptions The table below briefly describes the purpose of each port located on the toolhead PCB.
