## Customer Reviews

### ⭐⭐⭐⭐⭐ Huge timesaver...
*by N***B on December 22, 2021*

Great timesaver - easy to use - no reset switches to bother with, etc.I am new to all things Arduino and struggled to flash an ESP-01 boards I have with just the Arduino IDE based on wiring setups I saw on YouTube, etc. This device takes away all that extra work.Just a couple of notes if your run into issues getting setup:My first attempts on one Windows 10 PC weren't encouraging - Timeout packet errors, board not found errors, etc. when I attempted to upload a sketch. The setup doc link gives very basic instructions on setting up the device. I tried another Windows 10 machine I have and it worked right away - basically plug and play!I had inadvertently set the Reset Method for the Generic ESP8266 Module in the Arduino IDE to "no dtr" based on bad advice on the problem PC (should be dtr aka nodemcu). I also manually deleted the CH341 drivers and reinstalled them from the link provided in the vendor description. Problems corrected.

### ⭐⭐⭐⭐⭐ Better than the other 2 I tried - so much.  Worth the extra $1 (if that).  By far.
*by A***U on March 3, 2021*

This is better than 2 others I tried.Works with both ESP-01 & ESP-01s.Has as extra header, so you can connect to a breadboard while connected to the ESP-01(s) - soooo handy (though I wish they were on opposite sides...You don't need to unplug it & replug it in to program.I don't think you even have to press the reset button, it just works - programs, then resets & you can connect over serial.One I tried (Black one with yellow connector from MakerFocus) wouldn't program. You have to solder GPIO to GND to get into programming mode. I soldered in a button, but was janky & not ideal.Another I tried (Red one with yellow connector from WishIOT) has a switch, which helped, to switch from programming mode to serial mode that basically jumpered GPIO to GND.But this is just so much easier - none of that headache. Just works. (after you figure out all of the SW headache, but the HW just works...)

### ⭐⭐⭐⭐ Easier Programming ESP8266
*by J***R on October 5, 2021*

This device makes programming ESP8266 so much easier. No more manually resetting the ESP8266 and changing the selector switch every time you download a sketch (USB - Red version). Just Build and Upload and away you go. ESP8266 auto resets and starts running your code.
