32 Bit ARM Cortex Processor
BigTreeTech SKR 1.4 Turbo 32 Bit Processor

 
This powerful 32 bit ARM Cortex M3 processor boasts a peak operating frequency of 120Mhz. The LPC1768 processor family also incorporates high speed embedded memories, with 512 kB Flash memory and 64 kB SRAM.

This architecture is vastly superior to older 8 bit chips commonly found on 3D Printers, and even more powerful than many existing 32 bit boards. It's capable of handling thousands of calculations per second without a hitch, which means faster, more reliable 3D printing without missing steps or losing acceleration on curves.

 

Open Driver Sockets
