Since Archim2.2 is built on the shoulders of the Arduino community, makers and hackers should consider using this motherboard for additional projects beyond controlling a 3D printer.

Curious where the product's name comes from?  Archim is named after the mathematician Archimedes.

Parts Included

• One (1) Archim2.2 electronics board


  • Designed and Manufactured by UltiMachine

  • Logic

    • Archim2 is supported in mainline Marlin Firmware as BOARD_ARCHIM

    • Crystals for both usb and mcu (timing accurate to 10ppm)

    • 4 Thermistor jacks

    • All extra pins broken out on both processors (allows using the 32u2 for LUFA AVR programmer, etc.)

    • SPI (Serial Peripheral Interface) communicated motor current control (no tiny knobs to tweak)

    • Current limit on driver IC VCC to prevent permanent latchup

    • Microstep mode configured by MCU through firmware (no jumpers needed)

    • Test points for driver control signals

    • Step and Direction pins are on their own ports for synchronous movement capability

    • Extra driver ports broken out for up to 3 additional drivers (some of the motor extension pins are shared with max endstop and a pin allocated for SPI-SS extensions)
