ESP-WROOM-02

ESP-WROOM-02 Wifi Module

ESP WROOM-02 is a 32-bit MCU WiFi module with low power consumption featuring the ESP8266 MCU Wi-Fi, containing embedded TCP/IP network stacks, a 10 bit ADC and HSPI/UART/PWM/I2C/I2S interfaces. It contains the Tensilica L106 32 bit microcontroller and an ultra low power 16 bit RSIC. With its dimensions of 18mm x 20mm, the product can be easily integrated into PCBs and delivers high performance operation.

When the ESP8266EX operates in station mode, after connecting to the ap, the user can have an SRAM space of up to 50kb in the stack + data area.
