Elias Bakken has been working on Recore 3D printer control board based on Allwinner A64 processor since 2019 and with revision “A5” of the PCB, Recore is now considered stable and will ship to customers.īut wait? Isn’t Allwinner A64 just a quad-core Cortex-A53 processor meant to run Linux? But 3D printer control boards require real-time I/O and that’s why many are designed with STM32, Arduino compatible Microchip MCU or other microcontrollers.
