Raspberry Pi G-Code HAT

Overview

Author: [Matt Shepcar](https://oshwlab.com/matt_1626) Original project link: [https://oshwlab.com/matt_1626/pi-g-code-hat](https://oshwlab.com/matt_1626 /pi-g-code-hat) The Raspberry Pi G-Code HAT (Pig) simplifies wiring for the Voron 2.4 3D printer. It is designed to be used with this [motor board](https://easyeda.com/matt_1626/voron-controller-board_copy_copy_copy_copy) and [this tool head board](https://easyeda.com/matt_1626/voron-print-head -power_copy) can be used with the onboard STM32F407V to act as a USB host (or CAN bus controller, but this is still a work in progress), using [modified version of Klipper firmware](https://github.com/mattshepcar/klipper) to transfer data The package is routed from the Raspberry Pi to the tool headboard. For USB, the two solder links labeled USB must be closed to connect the MCU's USB lines to the micro-fit 3 connector on the motor board. There are four ZXMS6004 MOSFETs that can be used to drive light loads such as fans or solid state relays. This board is not designed to drive a heater directly. There are two thermistor inputs that can be used to monitor bed temperature and electronics enclosure or chamber temperature (the tool head plate can also be used to monitor chamber temperature). The STM32 and Raspberry Pi also include on-chip temperature sensors that can be used to decide when to activate the cooling fans. ![tTz2if4bf5NF0ZpqUoVZrxunpuNUZzAuKENGv1kn.jpg]
