TMC2209's will fit. The extra pins at the end just dangle. A number of people are telling me that they have them working on the MKS Gen 1.4 board but I personally can't get by the ''Unable to read tmc uart 'stepper_x' register IFCNT" alarm.

I am not sure how those will fair with an 8-bit mainboard running at 16hz but it would be worth checking out. For comparison the 32 bit mainboards run at 72mhz and go up from there. My BTT Octopus mainboards are running at 168mhz, literally a 10x bump in brain power from the 8-bit boards. While all of the 8-bit mainboards are the same exact thing (ramps+ATmega2560) the 32-bit boards all have different processors and run at varying frequencies and some have more memory than others. Your board has 256k flash size, most of the 32-bit mainboards double this and have 512k and some of them like the BTT Octopus Pro 429 mainboard have 1m of flash and will fit all of Rep Rap Firmware(RRF) making these the most versatile boards on the market as they will empower you to use any firmware you get the hair up your a$$ to try.

These days the Bigtreetech Manta is the board to have. Have you seen this mainboard, yet?
