Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

We confirmed today that the Planck Light PCB's were not flashed properly at the manufacturer and they are arriving without the bootloader. This means your keyboard will arrive functional and usable, but without reprogramability.
Right now we are working with Jack to restore the reprogramability that was designed to be there. At the moment we are looking to fix this by creating a module that will allow you to flash the PCB using the In-System Programming which should be the fastest and simplest method.
That said, we will need some time to create and test that module. We are evaluating timelines with our manufacturer now and will reach out to everyone with any updates and an expected ship date as soon as we have more information.
My apologies for this issue and we are working to get everything taken care of as quickly as possible.
We'll be making a device that we'll send to everyone so they can use it and load the bootloader onto the PCB. This will return the proper functionality to the Planck Light keyboard including the ability to reprogram it.
@jeffeb3 we are working with Jack on instructions and will post them for those that already can ISP flash.
If you have the QMK repo downloaded, you can find the at90usb1286's bootloader hex in the util directory. If not, you can find it on github.
As for the pin config, I'm not really sure.
What I did personally is use a header and a few of these jumpers: https://www.adafruit.com/product/266 connected to the appropriate pinouts on a teensy that I own with the teensyduino AVR ISP firmware flashed. I then hold the header to the board by hand to flash as the flashing process is over is <20 sec or so
