README
README.mdHuvud 3D Printer toolhead board
A very small 3D printer board for use on a direct drive toolhead. It is designed to be used with Klipper firmware. Klipper has the awesome feature to be able to use multiple MCUs connected to the host over a (relatively) high latency connection. Using CAN bus it is possible to chain many boards using just a pair of twisted wires and power. A good solution for multiple head 3D printers.
Features:
- CAN bus.
- One TMC2209 stepper driver for the extruder
- Two MOSFETs for fans
- One big MOSFET for the hotend heater
- Thermistor input
- Support for an endstop (or filament runout sensnor)
- STM32F103 72Mhz 32bit ARM MCU
- USB, for flashing firmware
Main power is 12-24V. 24V is preferred to keep the currents low
All done in KiCad and open source.

Questions
How big is the Huvud PCB?
It measures 42 × 42 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Huvud use?
126 parts, built around the STM32F103C8T6, SN65HVD230D, TPS54202DDC and ADXL345-EP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Huvud KiCad files?
From the bondus/KlipperToolboard repository on GitHub, at the commit this page was made from: the board is PCB/HuvudTiny2/Huvud.kicad_pcb and its schematic PCB/HuvudTiny2/Huvud.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Huvud design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
