This is the second updates of grid600 group buy.
The eletronic design for both PCB for Module Type 4 “FLASH” and Module Type 5 “PRESS” are complete. Hooray! We managed to set up an in-house electronics team in charge of PCBs and firmware.
Type 4 and Type 5 utilize very similar hardware, and both use Atmega 32U4 as a brain. Type 4 has two micro switches (Cherry DG2 1.47N) while Type 4 has 4 Kailh MX switches socket. As we said before, Type 5 is fully compatible with QMK firmware. We didn’t use QMK firmware for Module Type 4 “FLASH.” mostly due to the limitation of either the light effects and the size of ROM. Type 4 “FLASH” will ship with our firmware which uses Caterina bootloader and 2812FX library. There are a bunch of light effects and color you can choose right out of the box! (You can use QMK firmware on Module Type 4 if you insist.)
There is a 3D printed button holder in each Module Type 4 for greater haptic feeling.
Tap to change light effect. There are about 14 effects.
Press and hold to change color. There are 13 colors.
Module Type 5 working prototype.
Next update will be about manufacturing.
