Akruvia Indiv

A DIY soldering kit breadboard/protoboard adapter for hot swap Kailh Choc v1 switches.
You can also use this for handwiring a keyboard.
Bring your own Kailh Choc v1 switch and keycap.

Product inclusions:

1x Akruvia Indiv PCB
1x 1N4148 diode
1x SK6812 RGB LED
1x Kailh Choc(version 1) Hot Swap socket
1x 40pin male header

Akruvia Indiv PCB

Top and Bottom of the PCB

Akruvia Indiv Dimensions:

The 15.00mm x 15.00mm is the Kailh Choc v1 dimension


Solder the 1N4148 diode on D1.

Mind the orientation of the diode, the line on the PCB and diode indicates the correct orientation

Solder the SK6812Mini-E on D2.

(Mind the orientation of the SK6812, there’s a slant marker on the leg and the solder pad)
(If you’re using a 3.3v logic level microcontroller, it is recommended you have a logic level shifter)

Solder the Kailh Choc v1 hot swap socket.

Cut 2x 5pin male header from the 1x 40 pin male header.

Then solder the 2x 5pin male header.

Don’t forget to clean the residue from soldering

Pinout (Pins with the same label are connected internally):

The ones enclosed in black are the breadboard/protoboard compatible pins.
The ones enclosed in red are alternate wiring options.

V – Vcc of the SK6812Mini-E (Ideally 5v)
G – Gnd of the SK6812Mini-E
I – DIN of the SK6812Mini-E (Ideally 5v logic level, you can use a logic shifter)
O- DOUT of the SK6812Mini-E
A – the Kailh Choc v1 switch in series on the anode of the 1N4148 diode
C – the cathode of the 1N4148 diode

Switch-Diode internal connection:

Example Usage:

Direct input connection
Don’t forget to enable the input pullup resistor on your chosen microcontroller and invert the logic.
//Arduino example snippet for an Akruvia Indiv direct input connection
//switchPin is the MicrocontrollerPinInputPullup on the illustration
pinMode(switchPin, INPUT_PULLUP);

	//code here
Using the RGB LED (SK6812)
2×2 Example Matrix Configuration
MicrocontrollerPins1-4 are used for button matrix scanning.
MicrocontrollerPin5 is used for the SK6812 RGB LED.


  • You can use WS2812 libraries with SK6812
  • Don’t forget that the pins with the same label is internally connected so you can substitute any connection if they have the same label
