Shipping to CANADA: Sorry to say this but we had very long delay on delivery in Canada these days and it takes even two months occasionally when you suffer from bad luck. In the case of trouble you have to wait two months(plus a few week) before having me issue fully refund. If you are in Canada consider using EMS for shipping method, which is traceable and very fast(3 days or so) but it costs 20USD instead of 6 Let me know if you want to use EMS.




How to install
You need only screw driver to install this controller. No soldering is required.

And take a look this video. Thank you, stoic-lemon!

Open case
You have to void warranty from manufacturer to do this mod, of course.

More

Step 1: Void your warranty with getting rid of sticker and unscrew.


Step 2:  Crack it open using tool like phone openner or plastic card with care.


Step3: Done!

Mate/unmate connector
Check image below to know how to mate/unmate connector.

More

I recommend you follow method proposed by manufacturer and this works certainly for me.
You don't need any tool to remove/unmate the connector use just your fingers. Plier and screwdriver likely slip off and make scratch and give cables damage.
To remove/unmate hold many cables as possible with thumb and index finger and wiggle the connector laterally each side within 15deg range.
To insert/mate just push both side edge of the connector parallel with fingers or nails.

Install controller board
Just screw down controller PCB on case.




How to remap
Keymap Editor
You can use online keymap editor to get prebuilt firmware with your own keymap.

More

There are two kind of prebuilt firmware. Plain one has very simple keymap and  would be useful as start point if you want to define you own keymap from scratch. Emu one emulates FC660C stock behaviour, it would be nice if you like the stock keymap basically and need only small change.

- Plain: http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?fc660c
- Emu: http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?fc660c_emu

LED control
CapsLock LED indicates CapsLock state naturally in both Plain and Emu firmware.
Insert LED never light up with Plain firmware, which suits for people who have no plan on the LED or regard it distractive. Emu firmware turns Insert LED on when Layer 1 is activated, you can you can place your keymap there and make it indicator for your keymap state.
Not a fan of these behaviour? You can do anything with the LEDs if you willing to write small code, of course.

Keymap Examples:
- hasu's: spacefn and mousekey(Emu) https://goo.gl/HfpRFd
Share your keymap! Use 'URL shortener' button on keymap editor to get URL of your keymap and post it here.

You can grasp how this works by watching stoic-lemon's video.

Build from source codes
You can also tweak sources if keymap editor is not enough.

See this for detail.

NOTE
- No plan for USB-C C is a bit too large to plug in USB-mini hole.

More

- No Bluetooth This controller doesn't support Bluetooth, USB only. https://geekhack.org/index.php?topic=88720.msg2397757#msg2397757
- Not for FC980C I guess desinging controller for FC980C is not so difficult but problem is its costs and availability here. I cannot justify the cost to get it so far, I may need to run interest check on geekhack to know how many demand exists.
- Actuation point adjustment Not officially supported. See this post. https://geekhack.org/index.php?topic=88439.msg2403275#msg2403275
