The SparkFun ESP32-S2 WROOM Thing Plus module is a Feather-sized board featuring 2.4 GHz WiFi communication. Additionally, it is equipped with a cryptographic chip which, unlike the standard ESP32 and ESP8266 chips, allows encryption of wireless communication for secure network traffic. The board is additionally equipped with a Li-Pol battery charger chip through the JST 2.0 connector, through which the module can also be powered from the battery. ESP32-S2 supports a DVP camera interface, LCD interface and integrated temperature sensor. Additional Qwiic connector allows for connection of I2C devices. The Thing Plus module has 320 kB of SRAM and 128 kB of ROM, as well as 4 MB of SPI Flash embedded memory. There are 21 GPIO pins, a cryptographic chip, Qwiic connector, JST and USB C for programming and powering the board.
