1) ARM Cortex-M3 Series STM32F103RCT6 Master Controller with 32-bit Main Frequency of 72MHz Chip;

2) Carries highly modular open-source firmware Marlin 2.0, which facilitates user DIY and secondary development;

3) PCB board wiring is rigorous and beautiful, and has been specially optimized for heat dissipation.

4) Special power chip is used to support 12-24V power input.

5) Acceptable 24V input, the same power can reduce the hotbed current to 1/4, effectively solve the hotbed.MOS tube heating problem;

6) Supporting display :2.8 inch, 3.5 inch color touch screen and Ender3 printer LCD12864 screen;

7) Upgrading firmware by SD card makes operation simple and convenient.

8) Firmware is used to set the driving current so as to avoid burning out the driving caused by manual regulation of the current.Convenient, safe and reliable;

9) Support BLtouch, RGB color lamp, block detection, shutdown and other functions;

10) Integrate UART mode of TMC2209 to simplify debugging of motherboard and driver.

11) Reserve expansion ports for TMC2209 pins to facilitate users to use DIAG instead of Endstop.



Warning!!! this product is in the testing phase. The product description is a work in progress.

when I have tested the product myself and finished untangling the product description from the supplier the product testing price drop will end and the regular price will apply.

due to shortage of 2209 drivers, the ender mini board with integrated drivers has not been listed here. this is a listing for the ender 3 skr board with dip plugs so you can use whatever drivers you like. It comes with 2208 drivers installed. and should be correctly preconfigured out of the box. The description below may contain errors and information on other unrelated products as is typical with Chinese wholesale websites. When my sample package arrives I will confirm everything in the listing is correct and in working order and the introductory sale will end. I am only covering costs with this introductory price so jump in now if you want to be a beta tester, or wait for the price rise if you want to know it will just work out of the box.
