    (verified owner):

    They Work great and leave one slot on breadboard on each side to facilitate connection.

    Reset Button and Firmware Upgrade button make it really easy to program – a must have for any ESP07 & ESP12

    Works great – breadboard friendly!

    Works as expected, another great product from electrodragon, awesome quality at cheap price.

    (verified owner):

    A must for any ESP07-12 user. Simple to get running and the firmware button makes it so easy to program the ESP.

    (verified owner):

    I REALLY like this board, the only reason I gave it 4 stars rather than 5 is because I would have liked a breakout pin for 3.3v regulated output so that I could connect external pullups

    All you need for your ESP07-12, perfect to build a minimal developer tool for a comfortable programming experience

    (verified owner):

    Perfect for ESP-12. No more fiddling with custom breakouts to get the pitch correct. Worth the buy

    (verified owner):

    Easy to soldier and works great on breadboard.

  9. 3 out of 5

    (verified owner):

    Decent board, but it is not compatible with the new(er) release of ESP-12E extra I/Os and SPI pin interfaces: MTDO, MTDI, SD_3, MTMS, MTCK, SD_2 (GPIO10, GPIO9, CLK, CS, DI, DO).

    Great product, works as stated.

  11. :

    These boards are very handy.

    Be aware, the pins for GIPO4 and GPIO5 seem to be swapped.

    (verified owner):

    I got tired of making custom breakout boards for ESP12’s, and I bought 26 of these puppies. Very well designed, and very well priced.This was my first purchase from here, and I think i’ll be trying out their other products.

  13. (verified owner):

    jimmus is right, please update the doc to show txd, rxd, gpio5, and then gpio4.

    :

    Good breakout board for the ESP8266. Unlike some of the others, it is narrow enough to leave room for jumpers on a standard breadboard. Several of the other breakout boards I’d tried were too wide. Having the reset and programming button makes prototyping a snap.

  15. 5 out of 5

    (verified owner):

    Works as expected, and so easy to install on a breadboard, Ordered a few more for the 12F boards that I ordered. These little breakout are indispensible. Use the ESP-Link library to achieve UART transparent bridge mode and do cool stuff like wifi-debug, OTA updates etc.

    (verified owner):

    Really nice breakout board.
    It is very usefull for flashing a program with Arduino Ide.
    You press the flash down, then the reset once and then release the flash.
    Afterward you upload.
    Very good.
    Try to include the 3.3 regulator to all boards.

  17. (verified owner):

    are this boards compatible with esp-14

    Looks good and easy.

    (verified owner):

    These boards are great! They are still small and fit on a breadboard, and make setup and programming much easier. As noted in other reviews, the labels for GPIO 4 and 5 are reversed.

    Better than other pcb without componenet but i like a version with usb connector Thanks

    Easy to solder the esp module and cheap option for test.

  23. 4 out of 5

    :

    Nice board. I got a new revision. Has 3.3V and one extra GND.
    But I have problems flashing my ESP8266. On RX line there is a 1kOhm Resistor. After removing the resistor it works like charm. What ist the reason for this resistor?

  24. 3 out of 5

    :

    Hi, yes it is the new version, image not yet update.
    The resistor is to limit the current pass through if people use 5V-3v3 uart communciation, can limit the current and protect the uart pins somehow. It is a cheap but efffective solution. We have tested should work fine, will test it again. Thanks.

  25. 3 out of 5

    :

    Yes, the 10K/103 resistor may cause issue the board not enter into flash mode properly, can replace it by 1K or 0R resistor. Thanks for pointing out this issue.

  26. 5 out of 5

    (verified owner):

    Much easier than making a custom board for ESP units.

  27. 4 out of 5

    (verified owner):

    Nice board, but mine arrived buggy: RST button not working

    Hi, the button has unstable quality, we found the issue and solving it with new one. I will contact you for replacment, thanks for telling this.
