3D Scanner HAT interface board for the Raspberry Pi

This is part of a DIY project to build or upgrade a 3D scanner based on Atlas 3D Scanner and Piclop hybrid scanner. Runs the open-source FreeLSS software (freelss.org) on Raspbian or Ubuntu as a standalone device.

Designed as a Raspberry Pi HAT, it incorporates several additional and accessible features not present in the Atlas Scanner that include:
Boards are made, assembled, and tested in the USA.

Works with the Raspberry Pi 2 and Pi 3 ! (should also work with the Pi 4)

(Does not include Pololu DRV8834 stepper driver or Raspberry Pi)

Why did you make it?

I wanted to make a custom interface for use with the open-source 3D Scanning software, FreeLSS. I was very impressed with the Arduino-based Ciclop scanner and the Raspberry Pi-based Atlas Scanner. Several FreeLSS users merged the two scanner platforms, creating the PiCLOP 3D Scanner. However, there were few changes to the basic PCB design used for the scanner. I wanted to integrate the hardware functionality into a Raspberry Pi HAT format, with the inclusion of extra features for expandability --- and who knows, other uses !

What makes it special?

• Conforms to the Pi Foundation specification for HATs !
• 5V power design (only a single voltage) allowing for Pololu low-voltage stepper driver carrier.
• Connections for up to two independent soft-PWM controlled LED light sources.
• I2C interface for OLED displays and light intensity sensors, e.g. TSL2561 or TSL2591.
• Serial communication breakout for console support.
• Additional GPIO signal breakouts for other sensors and devices.
• User-programmable EEPROM ! for auto-configuration and device overlays.
• Standard DC power connector for up to 5V 4A power supply and connections for power switch.

• Over-current protection by poly re-settable fuse.

• Changes in Revision 2 - 3.3V output and swapped GPIO connectors (GPIO 4 and GPIO24) - permits use of PCA9685 16ch 12bit PWM/Servo controller Modules and other I2C devices requiring 3.3V input.
