The Vitamins included is a variant of the Let’s Split. It started out as a DIY kit for a version of the Let’s Split using kailh sockets, and then grew into the first revision. Lessons were learned and changes were made, and that got us to this version. The keyboard is named “Vitamins Included”, because no soldering is required. Everything is on the PCB.
The term vitamins is often used in reprap 3D printers to describe parts you can’t make yourself/have to buy, and as such was the inspiration for the name. Nothing super complicated :)
Like the Let’s split, it’s a split 40% board (4x6 on each half), that uses an ATMega32U4, and Serial or I2C to communicate between the halves. Revision 2 also has 6 WS2812B underglow leds on each half, and has spots for further WS2812 expansion, as well as a spot for a buzzer, if one wishes to add that.
The board ships with QMK-DFU and a default QWERTY keymap flashed.
The keymap used, is the vitamins_included/keymaps/default
The PCBs are available at Novelkeys
Rev2.0 is missing the pull-down resistors on the CCx pins. This means that it won’t work with USB-C <> USB-C cables, used in USB-C hosts. Using a USB-C <> USB-A adapter, and then a USB-A <> USB-C cable will however work.
The case was designed in Fusion 360. The right half is just a mirrored left-half
The PCB files are available on github
LED_Ojumpers on the right half. The labels are swapped, but are functionally identical to the previous revision.
|Side A||Side B|
|LED Mode||LED Out||LED Mode||LED Out|
Side A could be either side(left/right), and B would be the other. Also, the middle configuration functions as the first, but won’t allow for I2C. Any configuration using the Jack for RBG data, won’t allow I2C.
