X708 V2.0 Update:

  • Added protection circuit and alarm function when the battery is reversely connected (RESERVED will be on)
  • Supports the control of two kind of fan speeds(You can control the fan running at high speed or low speed via modify the CPU temperature threshold in fan.py script file )
