Furthermore I just wanted to add that while the RRF WiFi v1.0 board says it is for the SKR 1.4 and Turbo it is because of them shorty ribbons it comes with. This board can be applied to other boards just connected to the same exp1 and exp2 headers with maybe different ribbons. I point this out because the SKR processor on the 1.4 runs at 100mhz, the Turbo is running at 120mhz, and the SKR PRO runs at 168mhz: BIGTREETECH SKR PRO V1.2 32 Bit Control Board – Biqu Equipment . Also the BTT 002 runs the same cortex m4 microcontroller running @ 168mhz: BIGTREETECH BTT002 V1.0 32 Bit Motherboard with TMC2209 Driver 3D Prin – Biqu Equipment . The BTT 002 is a little cheaper and a smaller footprint so it might fit in your control box better than the SKR PRO. But the PRO is definitely the better board.
