EEI TECHNOLOGY ESP-TOOL

  • ESP burner based on CH343P.
  • Extremely low cost, BOM cost is only 1/4 of the CP210X solution
  • Has automatic download function.
  • It has the function of preventing power backflow.
  • USB interface ESD protection.
  • 3.3V and 5V outputs have been led out
  • IO0 EN can be controlled individually through buttons to prevent automatic download failure and burning failure.

Notice

  • When burning ESP32-S2, please reduce the baud rate to 460800, otherwise the burning will fail (ESP32 can be burned with a baud rate of 921600, the reason is unknown).
