About the Beyblock20 PCB
Beyblock20 is an open source PCB design by ChrisChrisLoLo, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 95.3 × 100 mm, with 51 components from 9 distinct parts.
Other key parts include the SeeeduinoXIAO and TRRS. By type, the board carries 20 switches, 20 diodes, 3 ICs, 2 connectors, 2 LEDs and 2 capacitors.
It belongs with the keyboards designs in this gallery.
From the project
The magnetic, modular, 20-key macropad that can join together to form an ortholinear board
A 20 key modular macropad that can connect with other elements to form a larger macropad via magnets. This versatile module in combination with the encoder module (knoblin3) can be used to form a 20 key macropad with 3 encoders, a 4x10 ortholinear board, or a 4x10 ortholinear board with 3 encoders! Each module has a Seeeduino XIAO on it, and all of them communicate on an I2C bus. Because of the I2C bus, more kinds modules can be made for an even more fine tuned and customized macropad/keyboard, as well as up to 128 devices to be connected together at once!
