Unihiker K10 not booting and black screen
TDrew 2026-02-12 09:49:14 134 Views3 Replies I have just unboxed my Unihiker K10 and ran a few of the example sketches from the Arduino, all was good. I loaded the next sketch and the LCD screen froze. I have tried many suggestions to reload the esp23 image, using Mind+ V1X now on Mind+ V2xxxx, flash tool, etc…., things have regressed now to just a black screen and a steady red led near the USB connector. I can hear/feel a few clicks when I press the reset button. The suggestions online usually end up being unable to follow as the screen and options don't line up with the instructions. Getting a bit frustrated now. Flashing Fire Beetles and pi micros are easy enough, but this has me stumped.
Hopefully there is an easy enough solution, looking forward to finding it.
You can try setting the K10 to forced burn mode, then use Mind+ to restore factory settings.
1. Press and hold the RST button on the back of the K10.
2. Connect the K10 to your PC via a USB-C cable.
3. Release the RST button.
Mind+ should now connect to the K10 normally, allowing you to restore it using Mind+.
Yeez_B As asked : I get this on the Arduino IDE when trying to upload an example sketch that previously worked, this was from power up start on the Unihiker. The screen remained black throughout. “Sketch uses 585073 bytes (11%) of program storage space. Maximum is 5242880 bytes.
Global variables use 22532 bytes (6%) of dynamic memory, leaving 305148 bytes for local variables. Maximum is 327680 bytes.
