Review on πŸ”Œ Stemedu USB to ESP8266 ESP-01 Serial Wireless Transceiver, 4MB SPI Flash WiFi Module, ESP-01S Prog WiFi Programmer and Downloader with Reset Button, CH340C Chip by Dave Rasic

Revainrating 5 out of 5

Works perfectly! Best-in-Network Transceiver

Installed the CH340 drivers, plugged in the device, selected it in the Arduino ports and was able to flash the ESP-01/ESP8266 with no problems. Draws about 4.5mA with no device connected, but I think it's a USB serial chip. Surprised this isn't a standard device sold with these things. Definitely a tool worth having!

Pros
  • 🚩 No connection required, no button press required, the ESP01S WiFi Programmer Downloader Module will automatically switch to download mode.
Cons
  • Too long to wait
