ESP-WROOM-S2 WiFi Module
The Espressif ESP-WROOM-S2 is a low-power 32-bit MCU WiFi module. This small SMD module integrates the ESP8266EX WiFi chip and is designed for optimal RF performance. The ESP-WROOM-02 enables you to evaluate and further develop the device for you chosen application.
This module features a low-power mode. ESP-WROOM-02 operated with a frequency range of 2.4 GHz to 2.5 GHz.
With a footprint of just 16 x 23 mm, the ESP-WROOM-S2 is ideal for integration into compact devices, where space may be limited.
SPI Flash (2 MB connected to HSPI)
Internal SRAM and ROM
The on-board ESP8266EX device features the Tensilica L106 32-bit microcontroller and a 16-bit RSIC.
