Pando - Right is an open source PCB design by jyap808, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 144.1 × 121.5 mm, with 70 components from 9 distinct parts.

Other key parts include the PCA9555PW and PRTR5V0U2X. By type, the board carries 29 diodes, 2 ICs, 2 resistors, 1 connector, 1 fuse and 1 capacitor.

It belongs with the keyboards designs in this gallery.

From the project

58 key split keyboard. Integrated STM32G0B1KBT6, USB-C interconnect, PCA9555 IO Expander design

Pando is a wired 58-key column-staggered split keyboard. It uses an integrated MCU design on the STM32 platform (STM32G0B1) with an IO expander (PCA9555) on the secondary half, connected over USB-C.

- STM32G0B1KBT6 MCU (64 MHz Cortex-M0+, 144 KB SRAM) - PCA9555 IO expander on the secondary half - USB-C split communication with ESD protection on all ports - Hotswap switch sockets - Single-sided SMD components for hotplate soldering - Vial firmware for keymap configuration - Same key layout as the Pando58, but as an assembled PCB instead of a DIY kit
