BLITZWOLF BW SHP2: Revision 12
infohttps://github.com/xoseperez/espurna/wiki/Hardware-BLITZWOLF-BW-SHP2 board markingsDifferent to board on this page, mine has following markings:
HYS-01-008_V3.4 boot loader modeShort GPIO0 and GND during boot to enter flash mode before connecting to the serial programmer. The power indicator LED will be strong red to confirm the device has entered this mode. As soon as the short is removed, the red color will be dimmed. The device will then be ready for flashing.

I can't recommend it at all, but I'm leaving my attempts below.... download pre-compiled binary and flash ithttps://github.com/xoseperez/espurna/releases/tag/1.13.5 root@x200:/mnt/nuc/esptool# wget https://github.com/xoseperez/espurna/releases/download/1.13.5/espurna-1.13.5-blitzwolf-bwshpx.bin root@x200:/mnt/nuc/esptool# ./esptool.py --chip esp8266 --port /dev/ttyUSB0 erase_flash esptool.py v2.7-dev Serial port /dev/ttyUSB0 Connecting....
