# Gboard Yunomi version with Pro Micro
|
|
|
|
This is an instruction to build the Gboard Yunomi version with Pro Micro.
|
|
For the general information about the Gboard Yunomi version, please refer to [the project README](./README.md).
|
|
|
|
|
|
### Parts
|
|
|
|
- Kailh choc key x60
|
|
- Diode (1N4148) x60
|
|
- Pro Micro x1
|
|
|
|
### PCBs
|
|
|
|
We need two types of PCBs to build this project.
|
|
|
|
|
|
|
|
#### Key-PCB
|
|
|
|
|
|
|
|
File location: board/key
|
|
|
|
Shape: Rectangular
|
|
|
|
Components to be soldered: Diodes and key switches
|
|
|
|
Number of PCBs required: 12
|
|
|
|
#### Base-PCB:
|
|
|
|
|
|
|
|
File location: board/base-promicro
|
|
|
|
Shape: Dodecagonal
|
|
|
|
Components to be soldered: Pro Micro
|
|
|
|
Number of PCBs required: 1
|
|
|
|
### Steps to build
|
|
|
|
#### Step 1
|
|
|
|
Solder diodes D1 to D5 onto the twelve Key-PCBs at the silk-screened locations.
|
|
|
|
*IMPORTANT:* Diodes on six of the Key-PCBs should be placed in the opposite
|
|
direction.
|
|
|
|
In other words, you can solder diodes as indicated by the silk-screen for six of them, and you need to solder diodes in the opposite direction for the rest six.
|
|
|
|
#### Step 2
|
|
|
|
Solder key-switches to each Key-PCB. Note that the diodes need to be placed on
|
|
the opposite side of the Key-PCB to the key-switches, as shown by the
|
|
silk-screen.
|
|
|
|
#### Step 3
|
|
|
|
Create a cylindrical shape by combining the 12 Key-PCBs.
|
|
|
|
There are six connection points between each pair of Key-PCBs. Connect adjacent
|
|
pairs of boards by soldering the tin-plated wires (see the picture).
|
|
|
|
However, only connect J11 and J12 between the first and last Key-PCB, instead of
|
|
all six locations.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
If you have a 3D printer, you may print and use jig.stl to help with this step.
|
|
|
|
#### Step 4
|
|
|
|
Solder a Pro Micro to the Base-PCB.
|
|
|
|
#### Step 5
|
|
|
|
Connect Base-PCB to the cylinder made in Step 3.
|
|
|
|
|
|
|
|
#### Step 6
|
|
|
|
Install [firmware](./firmware/firmware.ino) using the Arduino IDE. Note that you need to uncomment the line 2 (`#define PRO_MICRO`) to make it work with the Pro Micro version.
|
|
|
|
#### Step 7 (Optional)
|
|
|
|
Print and mount the platform (./platform_promicro.stl).
|
|
|
|
|
|
|
|
#### Step 8
|
|
|
|
Connect the keyboard to a PC or other device that has Google Japanese
|
|
Input/Gboard installed. Enjoy!
