Recore A8 – An Allwinner A64-powered 3D printer control board with TMC2209 stepper drivers

Recore A8 all in one desktop 3D printers control board

The Recore A8 is an all-in-one 3D printer control board built around the Allwinner A64 SoC. The board includes six soldered TMC2209 stepper motor drivers, cooled by an 8-layer PCB for durability. To make the connection better the board features industry-standard JST PH connectors for secure cable connections. Most of the connectors are flexible and support end-stops, Neopixels, servos, inductive probes, and BLTouch. Two Expansion headers on the board allow for two additional stepper motor drivers. Additionally, the board supports various temperature sensors, including regular thermistors, thermocouples, and PT100/PT1000 sensors (PT100 requires an extra board). Elias Bakken has been working on this board since 2019 and in our post about the earlier Recore A5, we have seen how Elias leverages Allwinner A64’s 300 MHz AR100 core to control real-time I/Os.
