Proofing completed , all keys are available after testing. The V1.3 version was added
on 2022-06-22
. The difference from the previous version is that the pin position has been modified. This layout is more suitable for Chinese people's usage habits.
Added a reset button.

Planck keyboard, 40% layout, three modes
Introduction: Planck three-mode PCB layout file, because it was drawn using other software, the 3D drawing of the light is sealed, and the actual layout will not be affected.


1. The only correction to the inverted shaft light is that the shaft seat may need to be polished before it can be installed.
2. Only steel plate satellite shafts can be used, and the space is limited.
The light control uses is31fl3733
8 bottom lights WS2812_5050
4 ws2812_2020 package status indicators (light 1: caps, numlock, light 2: Bluetooth 1: red, Bluetooth 2: blue, Bluetooth 3: green and 2.4G indicator: white, light 3 : Layer indicator, light 4: USB indicator) With driver, it can be modified at will.
Use U disk to drag and drop to upgrade the firmware.
