h87a - a fully-programmable PCB for custom a.87-layout tenkeyless (TKL) mechanical keyboards utilizing a USB Mini B connector.
At this point only normal thickness (1.6mm) is available.
The normal thickness (1.6mm) h87a is matte black with a matte black FR4 core.
The CEM3 variant is also 1.6mm thick. These were purchased as a "sample run" to test the viability and differences of CEM3 vs. FR4. Here is a short video showcasing the increased flex with CEM3: https://youtu.be/Z3CvPW0IHIc
The CEM3 h87a is matte black with a translucent CEM3 core.
