SparkFun WRL-17743 ESP32-S2 WROOM Thing Plus Board
SparkFun WRL-17743 ESP32-S2 WROOM Thing Plus Board is a highly integrated and feather form-factor development board equipped with a 2.4GHz WiFi System-on-Chip (SoC). This ESP32-S2 WROOM module features transparent external flash, RAM encryption, and secure boot that allows only signed firmware. The ESP32-S2 module includes HMAC and digital signature modules that use software inaccessible keys to generate SHA-MAC and MAC signatures. This 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. This thing plus board also includes a Qwiic connector, USB-C connector, and JTAG PTH pins.
