Title: [IC] Mini RGBW Board
Post by: HeroXLazer on Sun, 26 February 2017, 01:29:15: Have you ever seen a per key RGB ortholinear keyboard? I don't think they're many of them. Have you ever wanted something smaller than a Planck, but ortholinear? Have you seen any RGBW keyboards? This keyboard is a smaller version of the Planck, it has RGBW LEDs, it can support any MX switch. It has underglow and per switch RGBW. It does use Micro-USB as those cables are more common, and they're are magnetic versions of them. Also, the name is not final by any means. :) Here are some PCB renders and some quick Sketchup pictures. Leave feedback and criticism in the comments.

The reason I did the 1.5u key is just personal preference, and there's a space for the ATMEGA32U4 to stay nicely.

they're available but they're just very expensive (20 cents a pop) - Google for reverse mount rgb SMD led

rgbW and addressable? I have not been able to find any.

edit: just basic reverse mount RGBs go for 10-12 cents a piece (EASR3212RGBA0)

I bet he didn't consider the availability, cost of parts, and cost of pick&place :P

Post by: pomk on Sun, 26 February 2017, 06:31:42: Pick'n'place itself isn't that expensive. The cost of components, especially for the prototypes, are a lot more.
