Excellent product

For ESP8266 (ESP-07/12) Full I/O Breadboard Adapter

Well packed with extremely quick delivery from Singapore. Product looks well built with careful thought put into the design. Looking forward to testing it.

Thanks.
In fact I'm still fascinating why the delivery time for certain countries are so much shorter than others. UK and Netherlands are the Champion at the moment. Germany and USA have been varying between 3-20 days, while the South American and African countries are much slower.

Excellent dev board

For ESP8266 (ESP-07/12) Full I/O Breadboard Adapter

I had a stack of ESP-07s (don't recall where I got them, but there they were!). Anyway, due to the pin pitch of these boards, dev work is tedious. I was in the process of designing my own little pcb to make it easier when I stumbled across this, already designed, populated and proven!

It works perfectly - simple to solder on the 07, attach the FTDI cable and start development. In about 20 minutes after opening the (excellent) packaging, I was running a small webserver, 15 minutes after that it was reporting temp & humidity via a DHT22 - it really made things a lot easier.

Also, the programming switch function is a bit of genius, I definitely wouldn't have thought to add that to my plan. I'm not using the regulator, but it's nice to have that option.

my favorite

For ESP8266 (ESP-07/12) Full I/O Breadboard Adapter

By now I have a bunch of ESP8266 variations on the workbench - this one is my favorite.
I ordered mine with the ESP module included.
Mainly, it just works with no issues.
Some of my other breadboard projects with other ESP modules suffer from rf feedback getting into (maybe?) the USB comm lines or maybe the power. I don't have a scope so I'm not exactly sure.
Anyway - this little board doesn't have that problem.
Just be sure to ground the GPIO-15 line or else nothing will work right.

The supplied color printout of the pinout is very helpful.

I loaded the Lua firmware onto mine.

My initial experiment is a PIR sensor ticking an interrupt if someone's present.
Then it reads the temp/humidity with a DHT22, the light level with a photo-resistor /voltage-divider to the ADC pin, and logs it all to ThingSpeak. lt also sends out mqtt messages for my local mosquito/Node-Red setup.
Ton's of fun!

Its so good I just tried to order another one and I see they're out of stock.
My advice - put your email on the waiting list and get one as soon as you can!

Hi, Thanks for the kind review.
Would you please help me to measure GPIO15 voltage when it is floating? I have a 10K pull down resistor on that pin so by right, you do not need to ground GPIO15. But the resistor value IS sensitive (22K will not work). Perhaps I have to reduce the value further more.

Good idea, but arrived with broken switch and bent pins

For ESP8266 (ESP-07/12) Full I/O Breadboard Adapter

Update - replacements arrived and were carefully and securely packed. Thanks! Now onto development...

I ordered two, and they look like they will work and make things easy, except I will have to worry about the reset button on one and the bent pins on both. He wrapped them with a too small piece of foam and didn't put in any cardboard or box something else to prevent them from being crushed.
I just got them, so there was no "communication"

Thanks for the feedback. Seems padded envelope is not good enough for this purpose. Packaging is definately something I need to improve.
