ESP32-S2FN4R2

ESP32-S2F Low-Power 2.4GHz Wi-Fi Solution

Espressif Systems ESP32-S2F Low-Power 2.4GHz Wi-Fi Solution is a highly-integrated, low-power, 2.4GHz Wi-Fi System-on-Chip (SoC) solution. The ESP32-S2F features state-of-the-art power and RF performance. The SoC is ideal for Internet of Things (IoT), wearable electronics, and smart home applications. The ESP32-S2 family includes a Wi-Fi subsystem that integrates a Wi-Fi MAC, Wi-Fi radio and baseband, RF switch, RF balun, power amplifier, low noise amplifier (LNA), etc. The chip is fully compliant with the IEEE 802.11b/g/n protocol and offers a complete Wi-Fi solution. It features the Xtensa® 32-bit LX7 CPU that operates at up to 240MHz. The chip supports application development, without the need for a host MCU. The on-chip memory includes 320KB SRAM and 128KB ROM. It also supports multiple external SPI/QSPI/OSPI flash and external RAM chips for more memory space.
