### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Hands-off programming of ESP-01 - works great!
  

*by K***R on Reviewed in the United States on September 22, 2024*

I wish I had bought this years ago.  This has to be the easiest way to program an ESP-01.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great.
  

*by M***Y on Reviewed in the United States on April 23, 2024*

I thought I would have to wire an external jumper to get the upload to work, but after reading one other review where they had the settings necessary to auto-upload, I found out it works without having to have a switch or jumper. In the Arduino IDE, the flash mode must be "Dout" and reset method "dtr nodemcu".It is nice having the reset switch, restart the code while watching the serial monitor. It is also very convenient having the extra pin header for wiring jumpers to a breadboard while being powered by the USB port.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    One and only for Tasmota
