SparkFun ESP32 S2 Thing Plus - Qwiic

The SparkFun ESP32-S2 WROOM Thing Plus is a highly-integrated, Feather form-factor development board equipped with a 2.4 GHz WiFi System-on-Chip (SoC), from Espressif. The ESP32-S2 WROOM module addresses the security flaws in the original ESP8266 and ESP32 by featuring transparent external flash and RAM encryption, secure boot features allowing only signed firmware, as well as included HMAC and Digital Signature modules that use software inaccessible keys to generate SHA-MAC and MAC signatures! With the ESP32-S2's IoT and connectivity based application focus, this board provides a robust option for connected projects and applications.

SparkFun's Thing Plus footprint only adds to the board's feature set with the LiPo charging & power circuit making it perfect for home automation or wearable tasks. Possibly the biggest change for the S2 is the ULP (RISC-V) Co-processor. This allows you even more options to balance performance with power consumption over the original ESP32.
