Do I need to assemble this myself?
Yes, but no soldering required to get a basic keyboard with switches.

what is the limit of the number of writes to the on-board ROM? i.e. how many times you can flash the firmware before the device turns into a brick?

From what I could find out the Preonic uses the STM32F303 microcontroller. According to the datasheet, the flash has minimum endurance of 10k write cycles (page 82).

we used similar technology in a testing system, we had some boards that started failing, they had been running for around 5 years with writing to them 10s of times a day.

hi there, new bee here. Sorry if my question sounds stupid. The life cycle you mentioned here is counted 1 time everytime you change the setting and write to the board's ROM, is this correct? So can i assume that, for a normal user like me, we won't reach that 10K limit before finding our best comfortable combination, then hopefully no more writing to ROM? Thanks in advance for the answers. Cheers

That's basically correct. If you changed your mind and flashed your board 5 times a day, every single day, the internal flash might start failing after about 5.5 years :) I've had my Preonic for about 3 years now and I bet I haven't flashed it more than 30 times.

LED ready--meaning LEDs need to be soldered to the board (yes/no)?

The board comes with presoldered addressable LEDs around the edge of the board, other than that there is a cutout under each switch where you could put LEDs but there is nothing else other than the hole. If you wanted per switch LEDs you'd have to wire them separately.

Is this compatible with low profile MX switches like cherry low profiles or kailh choc?
