About the Apex-MUX PCB

Apex-MUX is an open source Raspberry Pi PCB design by ishantmahatopro, published on GitHub. It is a 2-layer board measuring 274.8 × 130.9 mm, with 90 components from 46 distinct parts.

Its main chip is the RaspberryPi_Pico_W, from the Raspberry Pi family. By type, the board carries 43 switches, 43 diodes, 3 resistors and 1 module.

From the project

A Blackmagic Design DaVinci Resolve Speed Editor with Slide Potentiometers, designed for budget video editors

A custom DaVinci Resolve Speed Editor you can actually build. Mechanical switches, slide pots, and a rotary jog wheel for the fraction of the cost. Starts at ₹13,432 (~$161 USD) instead of the $450 Blackmagic asks for.

I spend way too much time in DaVinci Resolve, and half that time is spent hunting through menus and digging for keyboard shortcuts. The Blackmagic DaVinci Speed Editor looked perfect—until I saw the price tag (₹43,000). That's ridiculous for what's essentially a keyboard with some sliders.

Apex-MUX: common questions

What microcontroller does the Apex-MUX use?

The Apex-MUX is built around the RaspberryPi_Pico_W, from the Raspberry Pi family.

How big is the Apex-MUX PCB?

The Apex-MUX measures 274.8 × 130.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Apex-MUX?

90 components, from 46 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Apex-MUX design files?

From the ishantmahatopro/Apex-MUX repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Apex-MUX design in my own project?

The repository has no license, so all rights stay with ishantmahatopro. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Apex-MUX without the hardware?

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