ESP-WROOM-02 is the famous WiFi module from Espressif System, the company that produce ESP8266 WiFi chip. This the SMD version with FCC/CE/TELEC certification.

This module is a highly integrated WiFi 802.11 b/g/n module that consumes extremely low power while providing a wireless internet connection for embedded devices. With a very small form factor (18mm by 20mm), this wireless module easily assimilates into resource limited devices. These features make it a great choice for OEMs to connect their IoT (Internet of Things) applications.

ESP-WROOM-02 is a 32-bit low power micro-controller (MCU) that integrates with TCP/IP network stacks; the included 10-bit ACD interfaces with HSPI, SDIO, UART, PWM, I2C and I2S. Programs and firmware can be stored in the integrated SPI flash with 16Mbits (2MB) capacity.

Note: This is SMD version, please consider take this ESP8266 module (ESP01), or NodeMCU if you are beginner.

What is the purpose of the bottom solder pad? I can't find the info about it in the datasheet. ( Adam Tan , 30/08/2019 )
Hi, it is for the cooling purposed. You can choose to solder it or not.
Hi, can this substitute for WiFi Serial Transceiver Module (ESP8266)? I very desperate to have wifi connection to my Maker Uno. But your wifi module out of stock too long~~ ( Finux Leong, 06/02/2018 )
Hi, yes you can. But this package is not suitable for beginner. You can consider to use our ESPresso Lite V2 and refer to ESPresso Lite V2 with AT Firmware tutorial. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
Where can I find the EAGLE library for this badboy? ( wroom02, 07/10/2017 )
Hi, sorry we do not have it. You may search online here is one of it, Eagle Library.
