Electronics

Electronics

Every board, sensor and probe that goes into a Klipper printer — mainboards, host computers, toolhead boards and Z probes, each entry sourced from manufacturer documentation.

MCUs & mainboards

The board that drives the steppers, heaters and fans. Choose on stepper-slot count, driver mode (UART or SPI), CAN bus support and processor headroom.

Stepper slots, driver sockets and UART/SPI jumper requirements
CAN bus and USB connectivity for toolhead boards
Verified pin assignments feeding the Klipper Configurator

Single-board computers

The host that runs Klipper, Moonraker and the web interface. Raspberry Pi, Orange Pi, BTT CB1/CB2 and the boards that take them.

RAM, storage and CPU against what Klipper actually needs
CM4/CM5 carrier compatibility and pin-header differences
Getting-started notes for flashing and first boot

Toolhead boards

A small board at the toolhead that collapses the wiring loom into a CAN or USB run. EBB, Nitehawk, H36, Hartk and the rest.

CAN bus, USB, CAN/USB switchable and passive breakout types
Form factors: 36mm, 42mm, Stealthburner, V0 and Hermit Crab
A picker on the Toolheads page matches boards to assemblies

Probes & bed scanners

How the printer finds Z zero and maps the bed. Eddy-current scanners, nozzle-contact probes, inductive sensors and deployable pins.

Which probes home Z themselves and which need a separate endstop
Accuracy, probing speed and whether the nozzle has to be hot
Config snippets that match the Klipper Configurator output

Addressable LEDs

Neopixel wiring and effects live in the Klipper Configurator, where the LED tab generates the [neopixel] sections and a live preview alongside the rest of your config.
