This product is no longer available for sale. The seller may be offering an improved version or it may be hanging out on the beach, enjoying the retired life.
I'm officially retiring this product, so to set aside more time into the new ESP32 development. For people interested in bare PCB you may find it on OSH Park https://oshpark.com/shared_projects/46d9l9Eg (thanks for whom put this up). You may contact me at firstname.lastname@example.org for more enquirers. Thanks for support.
LAST BUY. I decided to retire this product. Here is the last 15 units. For people who are still interested in the board, you may proceed to https://oshpark.com/shared_projects/46d9l9Eg order the bare board. If you cannot find the customized pin header, write to me at email@example.com. The last batch of 15 boards will contain a ESP-12Q module instead of the early ESP-12E.
New ESP-07 (1MB) in the house.
About v1.1 PCB. The new v1.1 PCB adds a pull-up resistor on GPIO0 pin, as recommended by Mr. Pete Scargill. The pull-up resistor improves power-on reset (POR) stability (hard reset on an already powered up chip is not affected).
New ESP-12E modules now available. The new module comes with 32Mbits (4MBytes) of flash, ideal for running ESP8266 Arduino with SPIFFS. ESP-07 (512KB) are now at discounted price.
ESP8266 is a powerful System-on-a-Chip (Soc). It has a 32-bit core running at 80MHz, 64KB of RAM and 512KB of external flash. This is many times of a standard Arduino (Leonardo/Micro, 8-bit, 16MHz, 2.5KB RAM and 32KB flash). WiFi stack on ESP8266 only takes 10% of system resource, left huge playground unexplored. ESP8266 also has every necessary interfaces sucn as GPIO, ADC, SPI, PWM and more. So why bottleneck all your application to the UART interface between ESP8266 and Arduino? You can do most of the things natively on a ESP8266.
This is a breadboard adapter for ESP-07 or ESP-12 ESP8266 WiFi module. It contains a 3.3V voltage regulator, a Reset/Program button and a UART connector with FTDI Basic compatible pinout. It is almost everything you need to develop on ESP8266.
The NodeMCU (https://github.com/nodemcu/nodemcu-firmware) project is a very handy Lua interpret on ESP8266. You can even use it to script standalone solutions. Advanced user may also consider Espressif SDK or RTOS SDK (https://github.com/espressif/esp_iot_rtos_sdk) for low level programming.
