Receive sensitivity reaches -97 dBm, giving it a solid link budget for indoor IoT applications where walls and interference are present. Onboard memory is 4 MB Flash and 2 MB PSRAM, which supports running a TCP/IP stack, TLS, and application logic without external memory. The serial interface set — ADC, I2C, I2S, SPI, PWM, UART — covers sensor integration, audio, and display peripherals. ## Supply and temperature range for industrial deployment Current consumption in receive mode is 63 mA to 68 mA; transmit current ranges from 160 mA to 310 mA depending on output power level.","metaTitle":"ESP32-S2-WROVER-I-N4R2 RF Module, 802.11b/g/n, 150Mbps","metaDescription":"Espressif Systems ESP32-S2-WROVER-I-N4R2 Wi-Fi module, 4MB Flash + 2MB PSRAM, 19.5dBm output, -40°C~125°C.
