Flash a D1 Mini V4 with ESP Home

To Flash a D1 MINI V4 with ESP Home, you have to

  1. Necessary equipment:
  • A D1 MINI V4
  • A good quality micro-USB cable (for data connection, not just power supply)
  • A computer with a USB port
  1. Software required:

Here I use the wifi which corresponds to the vlan which is not connected to the internet. The equipment will end up in 192.168.4.xxx
