Genuine Protoneer Raspberry Pi CNC hat v2.60 - GRBL v1.1 Compatible

Description

08/27/2018 Update
Version updated to 2.60
External driver boards (if the option is selected) include 4 unsoldered  boards with header pins, basic soldering tool required to put it together
Version 2.60
Added a Grove Connector to allow I2C connections directly to the Raspberry Pi.
Green Screw connectors changed from 3.5mm pitch to 3.81mm pitch.
Moved Stepper Drivers inline.
The RPI CNC Board Combines a Real-time CNC Controller (Micro-controller running GRBL) with a powerful credit card size computer (Raspberry Pi). By combining the two systems, Protoneer has created an eco-system where the Raspberry Pi provides benefits including processing power, connectivity (IOT) and a well-supported community.
Kit Includes:
Assembled Raspberry Pi CNC Hat only (
Raspberry Pi 3 Model B NOT included)
, Green removable screw connectors
(7 in total with each having 4 pins), Copper Mounting Spacers and screws
Specifications:
Protoneer RPI Hat
– The board plugs directly into the Raspberry Pi General Purpose Input/Output pins, with the micro-controller and Raspberry Pi communication via serial.
GRBL V1.1 PWM Compatible.
3 Axes (XYZ) + 4
th
that can clone X/Y/Z
Added circuitry for End-Stop and Probe signal
Filtering
Breakout Pins to connect external Stepper Drivers (Such as Gecko Drivers)
Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
Removable screw connectors
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
Runs on 12-30V DC
New in Version 2.58
Replaced the Arduino Nano with an embedded micro- Controller (ATMEGA328 – Arduino UNO Compatible)
Add reset circuitry to enable programming directly from the Raspberry Pi. ISP pins added and preloaded with the Opti-Boot bootloader. This opens the door for other firmware like Firmata.
Replaced clone jumpers with solder-able jumpers
Later batches might have dip-switches instead of Jumper headers
