# PostalPoint Hardware
|
|
|
|
This repository contains open source hardware and software for package drop-off lockers and parcel dimensioning.
|
|
|
|
Devices are built around the Pi Pico and MicroPython, and support both bidirectional USB HID and serial 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.
|
|
|
|
There is currently no schematic or board layout, as the entire device is a Pi Pico, a sensor, a display, and eight wires to connect them.
|
|
|
|
