This build guide features the choc (low profile) variant of the Sofle V2, but the build guide will be the same for the MX variant too!
First things first, let’s check we've got everything included in the kit. If there’s anything missing, send us a message so we can get you back to the build ASAP! (Spares are included in the contents below)
1 x PCB
2 x Reset switch
2 x nRF52840 BLE Controller
2 x Switch plate
2 x Rotary encoder + knob
4 x Controller socket
2 x Frosted acrylic backplate
5 x 12mm Standoff
50 x Mill-max pins
2 x Acrylic OLED cover
12 x 6/8mm Standoff (choc/MX)
2 x E-Ink screen + socket
60 x SMD diode
16 x 4mm Screws
2 x 110mAh LiPo battery
60 x Hotswap socket
16 x 6mm Screws
10 x Rubber feet
There are a couple of parts that are required for the build that aren't included in the kit, hopefully you've already got these:
60 x Switches of your choice
1 x Set of keycaps
Here's a list of the tools you need to build the keyboard:
Soldering iron
Phillips head screwdriver (M2)
Tweezers
Solder
Snippers/Cutters
The first components to add to the PCB are the SMD diodes. We can get started by applying a small amount of solder to one of the pads we're attaching the diodes to, as shown below:
Once the pads all tinned (soldered), we can add the diodes by melting the already placed solder with our iron and gently placing a diode leg into the solder and then leaving it to harden in place. The line on the diode should be facing the same side as the line on the PCB, as pictured below:
Now we just have to solder the remaining diode legs to their pads:
Now for the hotswap sockets, I tend to find it easiest to place all of the sockets in their outlined positions and then solder them into place one side at a time.
Next is getting our controllers onto the board. The new Sofle V2 kits include machine pin sockets and pins, we recommend using them to make replacing/upgrading your controllers easy. First off, insert the sockets into the top side of the PCB (opposite to the side with the hotswap sockets), soldering the top and bottom pins to secure them.
Be careful to only adjust using the middle of the sockets, heating the solder can cause the end pins to become very hot
From here we can heat the solder on these pins and readjust them until they're flat and straight:
Now that we've got the sockets in position, we can solder the rest of them. Once we've secured the sockets, we can insert our socket pins. I'd recommend placing the pins into the sockets with tweezers, and then using something flat to push the pins in completely, being careful not to bend them. Here I'm using the other end of the tweezers:
Once we've got the pins into position we can place the controllers component side down onto the pins/sockets, from here we can solder the controller to the pins (being careful not to heat them for too long, as this can cause the solder to travel down the pin and flood the socket):
When using our controllers, make sure the pins start at the bottom of the controller, leaving the top ones empty!
The E-Ink sockets are a similar process to the controller sockets, soldering one pin, heating/adjusting, and soldering the remaining pins:
Once the OLED sockets are installed, we can insert the OLED screen. To make it a flush fit, we'll need to trim the pins with some flush cutters:
Now is a good time to give your build a test, so you can troubleshoot any issues before screwing the case together. Feel free to get in contact if you run into any issues.
Now we've got a few different components to add on, the process for all of these will be similar to the previous steps!
Next are the reset switches, these tend to stay in place with the friction from the pins once inserted:
Finally, we can solder the rotary encoders, using the same method as above. It's worth noting the bigger pins are purely for support, so they don't have to be soldered perfectly:
Once they're soldered, we can push on the rotary encoder cap!
Almost there now, just a couple more steps to go! We're going to start by screwing our 6mm (choc) or 8mm (MX) standoffs onto the frosted acrylic bottom plate, using the 6mm screws.
Now we can grab our switch plates and pop a few switches into the plate, and then insert these switches into the PCB, being sure to check the pins are straight and aligned with the hotswap sockets:
Once we've got our plate in place, we can begin to insert the rest of the switches. Sometimes the plate can drop in this process (mainly choc builds), but that's no worry, the plate tends to come back up when installing the keycaps, or we can use something thin to pop the plate back up into position:
Next up, we're putting the 12mm standoffs with 4mm screws onto the PCB, these will be what we're attaching our acrylic OLED covers with at the end of this step.
We can now finish assembling the case by placing the PCB and switch plates onto our pre-prepared bottom plates, and screw them together from the top, with 4mm screws.
Finally, we can screw on our acrylic OLED covers with the remaining 6mm screws:
Be careful not to screw these too tightly, acrylic is fragile!
And that's it, you should now have a complete Sofle V2 to get typing on!
We recommend flashing your controller before beginning this step, just to check it's in a working condition. If you're unsure how to do this, check out our wired pre-build page, this has instructions on how to flash your controller:
Our final step here is a nice and easy one, we can now install our preferred set of keycaps! This is as simple as matching the keycaps to our layout of choice, and pushing them onto our switches. If you're using (or any that's via compatible), you can view/alter the layout here:
