# Seven Segment Display Input Module

![image](MainBoard/MainBoard.png)

This module is based on the "34x9 LED Matrix" example

from https://github.com/FrameworkComputer/InputModules

and is powered by a Raspberry Pi RP2040 microcontroller.

A short video demo of first light from the prototype is at

## Fabrication and Assembly

A 0.8mm PCB is required.

Most components are SMT on the bottom side of the board; the

[seven segment displays](https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VDMR10A1/4327669)

and [side-firing neopixel LEDs](https://www.digikey.com/en/products/detail/adafruit-industries-llc/4691/13170955)

are on the top side.  If you use a PCBA service, it is most economical

to have the bottom side assembled and then hand-solder the small

number of top-side components.

In addition, the [threaded inserts](https://www.digikey.com/en/products/detail/keystone-electronics/24929/16343672) are not generally stocked by JLCPCB

and so are probably easier to hand assemble.

A bezel for the board, which can be 3d printed, can be found in

[LEDMatrix-cover-Body.step](./LEDMatrix-cover-Body.step).  This was

designed in FreeCad and the source is `LEDMatrix-cover.FCStd`.

It is intended that 4mil transparency be used to create legends

for the different sections of the display, and then the entire

top surface be covered with 0.2mm ND film to achieve a consistent

look.  A template for the legends is in

[LEDMatrix-template.pdf](./LEDMatrix-template.pdf) and sample

legends ready to print (or modify!) are in

[LEDMatrix-sample-legends.svg](./LEDMatrix-sample-legends.svg).
