About the Cosmos docks PCB

Cosmos docks is an open source PCB design by holeminhnhat3101, published on GitHub under the MIT license. It is a 2-layer board measuring 76.6 × 81.5 mm, with 55 components from 11 distinct parts.

Other key parts include the SN74LV1T34DBV and MOUDLE-SEEEDUINO-XIAO. By type, the board carries 15 capacitors, 13 LEDs, 10 switches, 9 diodes, 5 resistors and 2 ICs.

It belongs with the displays & leds and keyboards designs in this gallery.

From the project

Cosmos-docks is a custom hackpad created by me. It includes a custom PCB, a fully 3D-printable case, one rotary encoder, an OLED display, and SK6812MINI-E addressable RGB LEDs. The design is built around the Seeed XIAO RP2040 and uses QMK firmware.
