It belongs with the displays & leds designs in this gallery.

From the project

USB 10 digit seven segment display unit

This seven segment display module is specifically designed to work with POS systems and banking applications. Initially, this module is developed to work with PC based systems, and later it was modified to work with other platforms and applications.

To simplify the communication interface this unit emulates a COM port in the host terminal. Because of this feature, this module can work with many systems without having any additional device driver(s).

Usb external display: common questions

What microcontroller does the Usb external display use?

The Usb external display is built around the STM32F103CBT6, from the STM32 family.

How big is the Usb external display PCB?

The Usb external display measures 149.5 × 43.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb external display?

65 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb external display design files?

From the dilshan/usb-external-display repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Usb external display design in my own project?

Yes, under the terms of its MIT license, which dilshan chose for the repository.

Can I test firmware for the Usb external display without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
