PostalPoint Hardware
This repository contains open source hardware and software for package drop-off lockers, parcel dimensioning, and barcode scanning.
Devices are built around the Pi Pico and MicroPython, and support bidirectional USB HID communication with a host computer.
Devices
Parcel Dimensioner
This device uses a US-100 or Parallax Ping ultrasonic sensor to measure the height of a package and transmit the size to a PC. By rotating the package, all the dimensions can be determined.
It optionally supports output to a SSD1306 OLED screen and hardware buttons for zero/tare and unit switching.
The PCB files assume a US-100 sensor, two 6mm tactile buttons, and a 128x64 SSD1306 OLED module.
Installing
The files in src/dimensioner must be copied to the Pi Pico.
Dependencies: Install these MicroPython packages on the Pico: usb_device_hid, ssd1306
Package Locker Kiosk Controller
See source code in src/kiosk and schematics.
Barcode Scanner
A handheld barcode scanner that uses the USB HID POS specification, as well as serial, for transmitting scanned barcodes. Supports most common cheap Chinese barcode scanner engines.
