Sofle RGB v2.1 SofleKeyboard Photo Build Log
You can get the hardware from one of the following links.

VIA Firmware
This is a firmware modified from the v1 VIA firmware with the following lines added to the
config.h#define RGBLED_NUM 72
#define RGBLED_SPLIT {36,36}
SPLIT_USB_DETECT is required for some of the pro micro boards.

This guide assumes you have some keyboard soldering experience. There are multiple ways to build the Sofle RGB Keyboard v2.1. Here is a build with 72 RGB LEDs, two rotary encoders, and two OLED display modules.
The Front side is for the pro micro controller boards, OLED display modules, TRRS jacks, reset buttons, rotary encoders.
The Back side is for the diodes and Kailh MX switch hotswap sockets.
There are RGB LEDs on both sides.
On the Front Side, bridge the 4 solder pads on left hand PCB and right hand PCB.
Flip to the Back side, solder all the diodes on both sides. Diodes are directional.
A common mistake is, we miss the diode near the rotary encoder.
do not bridge the solder pads on the back
The OLED solder pads should NOT be bridged on the Back side.
All the diodes are soldered.
Align the two controllers according to the silkscreen outline. The boards should be mounted with the components facing down.
The same applies to a generic pro micro controller board.
Back Side
The back side should look like this.
You now have a minimally working, single-sided keyboard.
If you connect the left side, or the right side to the computer, and short the hotswap solder pads (front or back), you should be able to enter some keys.
Solder the hotswap socket according to the silkscreen. A common mistake is to mount it 180 degree rotated.
Make sure the sockets stay flat.
Solder the rest of the sockets.
If you plan to add the RGB LEDs, you should skip this step and move this to the last.
Bridge "IND", "UND&BL", and "ENA" on the back side.
Set the soldering iron to a low temperature (around 280°C or 530°F). Extra flux is helpful. Start with the indicator LED. See RGB LED Orientation and the ordering at the Official Build Guide.
Droplight
Flip to the Back side and solder the second RGB LED.
Complete the 6 droplight RGB LED. And start with the per key lighting.
First per key lighting
Testing the first per key lighting
Bridge "IND", "UND&BL", and "ENA" on the back side.
