[To be verified] Simple director keyboard

Overview

[To be verified]

A guide keyboard based on Arduino Pro Micro HID, aiming to be compatible with vmix, resolune, obs, etc.

8 illuminated buttons can be used for switching (those illuminated buttons are hard to buy, so they are replaced with mechanical keyboard shafts. In theory, the feel should be similar?), and two sliders can be used for switching and volume (the pushrod is too big, So it’s the slider).

The keyboard is a 2x4 matrix, the LED uses a MAX7219 chip, and the slider is directly connected to the analog input.

The program has not been written yet, but it is expected to use the MIDI protocol to prevent conflicts with ordinary keyboards and at the same time ensure the normal use of the slider.

I have reserved a position for nrf24l01. I wonder if I can make a wireless tally light.

2020/6/21 The board is finished.
2020/6/24 Changed from one set of LEDs per button to two sets.

Continue to update.

PCB copper plating problem
The hardware guy in our company drew a board and wanted to modify it by adding a wire, but the guy resigned.My boss asked me to do it. I added a wire directly to the PCB without going through the sche
