About the ENV KB PCB

ENV KB is an open source RP2040/RP2350 PCB design by Envious-Data, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 347 × 156.3 mm, with 202 components from 18 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 97 LEDs, 93 diodes and 1 switch.

It belongs with the keyboards designs in this gallery.

From the project

A custom mechanical keyboard inspired by the CFTKB Mysterium utilizing the Raspberry Pi Pico

- Project Name: EnvKB80 - Nickname: Delirium

- 10x m2 female standoffs 10mm - 20x m2 screws <5mm

(this list may not be totally accurate since I often forget what has changed inbetween when the readme is updated.

the type-c port may be difficult for some to solder so use loads of flux and minimal amounts of solder, its best to solder the large 4 outer pins of the shell first.

ENV KB: common questions

What microcontroller does the ENV KB use?

The ENV KB is built around the Pico, from the RP2040/RP2350 family.

How big is the ENV KB PCB?

The ENV KB measures 347 × 156.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ENV KB?

202 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the ENV KB design files?

From the Envious-Data/Env-KB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ENV KB design in my own project?

Yes, under the terms of its GPL-3.0 license, which Envious-Data chose for the repository.

Can I test firmware for the ENV KB without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
