Walfront MKS TinyBee V1.0 3D Printer Control Board with WiFi Connection and Flash Storage Chip Compatible DC 12‑24V

Update: Powered via 24VDC option and at least it works that way. Serial port is dead though. Hopefully OTA updates always work. Board was working fine then one day did not power up. I was finished bench testing temporary hook up wire, steppers/drivers. I disassembled got all mounted on a backplane for enclosure. Plastic standoff for the board (it did not short to the metal backplane) Then just did not power up. Just through the USB port as I had in bench testing. USB power jumper still in place. None of the surface mounted fuses blown. USB power is good. IDK what happened. Only thing I can think is the board flexed a little when screwed tot he back plane and broke a weak trace. Ordered another. We shall see.

Used this for my 3018 CNC so I was not able to check out the 3D printer portion of the board like the hot bed, etc. Easily installed FluidNC and calibrated the X, Y and Z axis as well as added limit switches. Wifi control through the FluidNC web page worked fine. SD card worked just fine. I was also able to connect up a probe and a spindle relay. Very satisfied with the product.
