Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! This module contains an ESP8285, which is an ESP8266 processor with 1MB of FLASH memory already built in. You can use it just like an ESP8266, it's the same processor and WiFi capabilties as The ESP8266 processor from Espressif, which is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. Because the ESP8286 contains the FLASH memory inside the chip, the modules that use it are much smaller and a little less expensive too. These modules are very easy to hand solder, with big pads! Comes with that 1 MB internal flash, ESP8266 processor, and onboard antenna. These come pre-progammed with the NodeMCU Lua firmware, so you are ready to rock.
