Introduction: The ESP8266 microcontroller integrates a Tensilica L106 32-bit RISC processor, which is extra-low power consumption and reaches a maximum clock speed of 160 MHz. 80% of the processing power is available for the developers using. And there's a lot of resources available for the ESP8266's development, and ESP-01S module is compatiable with Arduino. Specification: Package: DIP-8 Flash: 8Mbit Dimension: 24.7*14.4*11.0mm Serial/UART baud rate: 115200 Antenna: Onboard Update Version of the ESP-01, totally compatible with ESP-01, while have a better performance and recommoned to replace the ESP-01 with ESP-01S

Almost didn't order, but..
I almost didn't order these after reading reviews and seeing someone mention that these were 512k. The seller must be reusing old sales pages with new/updated items, because these ESP-01S's are definitely 1MB, as any ESP-01S should be.I've only used one, and tested one more. Both worked great. I'll update this review if I run into any issues with the remaining two.Prior to uploading your sketch/firmware, do yourself a favor and Erase the chip with Flash Download Tools. Aside from that, don't hesitate to grab a pack of these if you're on the fence! You definitely won't find a better price for a four pack this side of the Pacific Ocean.

Cheap wifi for arduino
Pretty cool devices. A little tricky to get started with as some of the info out there is dated, and you seem to need to hack off the baud rate a little to get robust communications.

Basic ESP8266, inexpensive
512K as expected, but it works fine - all 4 now have different firmware so I can experiment

Didn't work
Tried to download a program from my Arduino IDE. none of then seemed to power up

Works good price good
works like a charm.. have use them in a few alarm systems I have built for friends.. no problems

Slight pain, but does the job with work.
A little bit of a pain in the arse to set up. I had to flash it five times before it accepted my firmware. Once it was set up, it worked just as it should though. If flashing with ESP, as soon as the name changes to ESP3D you know its flashed. If it has ESP and a bunch of numbers after that when you connect to it via wifi still, it didn't accept. The default ip on mine using ESP3D before it changed to local was 192.168.0.1 and the password before it was changed was 12345678 there are othe ip's and passwords depending on the firmware flashed to it.
