Raspberry Pi CNC Hat V2.60 - GRBL v1.1 Compatible - Extra Options

Description

Specifications
:
New in Version 2.60
Added a I2C Grove connector that connects to the Raspberry Pi's I2C pins(3.3V only). This makes it very easy to add Grove sensors , inputs or outputs directly to the raspberry Pi.
Cleaned up design with embedded Arduino Uno compatible micro-controller (ATMEGA328).
The hat can now be programmed directly from the Raspberry Pi.
Pre-loaded with the latest GRBL firmware v1.1.
Compatible with other firmware like Firmata for use in robotic / automation projects.
Features:
GRBL V1.1 PWM compatible. (Open source firmware that turns G-code commands into stepper signals)
3 Axes (XYZ) +
4th that can clone X/Y/Z
Added circuitry for End-Stop and Probe signal filtering. This eliminates false triggers and makes it possible use non-shielded cable for end-stops/probes.
Breakout pins to connect external Stepper Drivers like Gecko Drivers.
Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
Uses removable screw connectors to make it very easy to wire up.
End Stop for each Axis and Probe.
Variable Speed Spindle / Laser Intensity control (PWM Spindle pin and Direction pin)
Coolant control pin. (Extra output pin)
Jumpers to set the Micro-Stepping for each stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
Runs on 12-30V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Assembled board ready to run.
Compatible with Raspberry Pi Models
:
Raspberry Pi 4
Raspberry Pi 3 and B+
Raspberry Pi 2
Raspberry Pi B+ (The one with the 40 pin headers.) (It is possible to use the Raspberry Pi Zero but the board will need extra support/spacers.)
