RP23U5XBB Breakout Board
This breakout board with open source grblHAL firmware creates a powerful 5 Axis CNC motion controller for devices like routers, mills, lasers and lathes. Powered by the powerful Raspberry Pi RP2350B microcontroller and using grblHAL, it forms the basis of a motion control system with advanced features
Key features of the RP23U5XBB.
-
Supports up to 5 Axes via Screw Terminal and Pin Header.

Separate power input for full isolation
-
Opto-isolated
-
-
Relay support
-
Directly drive up to 7 relay coils via open collector outputs.
-
Relay Coil voltage selectable between +5V or +12V.
-
Drive up to 7 SSR or Logic Level relays.
-
-
Opto-Isolated standard Grbl input controls: Cycle Start, Feed Hold, EStop and Safety Door.
-
Opto-Isolated Probe input.
-
USB and Ethernet connection support.
-
Micro SD Card socket. Allows storage of GCode programs. GCode programs may be run from the SD Card.
-
Dust Collection support.
-
Dust Collection relay and TTL output ganged to Spindle.
-
Header for a switch to manually run Dust Collector.
-
-
Flexible power input. Two 12V sections, one for Stepper/Servo output, relays and spindle control, one for isolated limit, probe and control inputs. The two sections may be joined for the budget conscious builder. On board 5V generation.
-
LED indicators for 12V inputs, USB, spindle active, Limit Switches (5), Probe, Control Inputs (4) and Servo Alarms (5).
-
Open collector outputs allow adding pull-up resistors on the board.
-
Expansion headers for I2C, SPI and UARTs (2). UART 0 has 3.3V/5V translation support.
-
Powered by open source software - grblHAL.
