Can Model 100 extend limit of 8 layers?

Hi!
I heard that model 100 hardware is much better then in atreus and model 01. And memory limit for a firmware is not a thing anymore.
It would be great if it’s firmware 8 layers limit extended a bit. Need one more layer, please.

Yes it supports more than 8 layers. You’ll need to build a custom firmware with various places 8 is used to increase it. The GD32 MCU in the Model 100 is currently allocating 16k of flash to virtual EEPROM. The AVR in the Model 100 only has 1k, so you can see there’s a lot more space to work with.

This post has a lot of relevant info too:

So what does the GD32F303 controller bring us, in real-world applications?

Compared to the ATmega32U4 in the Model01, the GD32F303 brings us: More RAM (2k → 98k) More Flash space (32k → 1mb) More “EEPROM” space (1k → 16k) More powerful MCU (16Mhz → 120Mhz) Hardware availability The last part is crucial, you can’t build a keyboard if you can’t source its MCU. As far as I remember - but @jesse will correct me if I’m wrong - the former ATmega32U4 chips just weren’t available. (See here and the “Production status” part of the campaign.) But availability aside, the most…
