This repository contains the hardware design files for the kinX mk66f keyboard controller, a replacement controller for the Kinesis Advantage keyboard.
You can order this PCB at OSH Park.
You can order the components at Mouser
Note that the bootloader chip IC_MKL04Z32_TQFP32 is not included in the BOM
and is only available from PJRC’s shop: https://www.pjrc.com/store/ic_mkl02.html
Also note that micro USB cables are not included in the BOM (you’ll need one for power and firmware flashing, another one for USBHS data). I recommend building the kinX hub, whose BOM includes the USB cables and which is a drop-in replacement for the hub that comes in the Kinesis Advantage keyboard: https://github.com/kinx-project/hub-hw
