grblHAL Breakout Boards
We have 3 CNC controller breakout boards based on grblHAL available.
T41U5XBB is a 5 Axis controller based on the Teensy 4.1. It supports USB and Ethernet connectivity. Very high performance and flexibility. Supports auto-squaring, moving gantry plus rotary axis machines. more information.
RP23U5XBB is a 5 Axis controller based on the Raspberry Pi RP2350B microcontroller. It supports USB and Ethernet connectivity. High performance flexibility. Supports auto-squaring, moving gantry and rotary axis machines. more information.
PicoCNC is a 4 Axis controller based on the Raspberry PI Pico and Pico W. It supports USB, WiFi (via Pico W) and Ethernet (via a plug in module) connectivity. Cost effective solution. Supports auto-squaring, moving gantry CNC machines. more information.
