About the Panel PCB

Panel is an open source PCB design by da1sh1n, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 273 × 119.9 mm, with 72 components from 33 distinct parts.

Other key parts include the SN74LVC1G17DBVR, E73-2G4M08S1C, SN74LVC1G74DQER, S2B-PH-K-S(LF)(SN) and BL8573CS8TR. By type, the board carries 20 diodes, 19 resistors, 11 capacitors, 10 ICs, 2 transistors and 1 crystal.

It belongs with the keyboards, iot & wireless and power & battery designs in this gallery.

From the project

Wireless split keyboard · nRF52840 · ZMK · hexagonal keycaps

Wireless split keyboard · nRF52840 · ZMK · hexagonal keycaps

A low-power, battery-powered wireless split keyboard. Each half is a fully independent BLE device with its own battery, per-key LEDs, and USB-C charging.

Right now: finishing the PCBs and panelizing for fabrication. After that: fabrication → SMT assembly → hand-soldering → firmware → testing → case design.
