The board is the third generation of a design I call the "Overton130". The PCB has now been designed to accept either MX or Alps switches, and either a Teensy++ or a nanoCH32V305. This example is built with Box White v2 switches and various cheap stabilizers (originally Everglide Pandas, but I had to replace a few sets that were damaged from overly enthusiastically removing keycaps).
The main red keycaps are from a G-MKY "Pega" knockoff; the colour's a little darker, so it needs more light to really shine, and the typography isn't as classy as real Pega-- it's clearly aping the Cherry font-- but it's actually available and like $25 per set off AliExpress.
The white keys are generic OEM profile PBT caps, marked with a laser engraver to sear dry-erase market ink onto the cap; it's not the most durable thing in the world, but good enough for occasional hints like media control. The blue "Rawr" key is from the GMK a run.
Many of the keys in the top row are bound to unique features of the CH32v-Keyboard firmware: adjustable "mode" for the OLED display, tuning the debounce and post-debounce hysteresis thresholds, and activating the mini-RPN-calculator mode. The six on the top left are just vanity "Walter Mitty effect" legends until I find use for the extra bindings. Despite the labelling, "Rawr" does nothing, but "Less Rawr" is "Stop" and "Run Stop" is play-pause.
