With the ESP32-S2's IoT and connectivity based\r\napplication focus, this board provides a robust option for connected projects\r\nand applications. .All of that can sound a little daunting, but we assure you\r\nthat the ESP32-S2 Thing Plus is anything but! SparkFun's Thing Plus footprint\r\nonly adds to the board's feature set with the LiPo charging \u0026amp; power circuit\r\nmaking it perfect for home automation or wearable tasks. Possibly the biggest\r\nchange for the S2 is the ULP (RISC-V) Co-processor. This allows you even more\r\noptions to balance performance with power consumption over the original ESP32.\r\nAdditional new features of the ESP32-S2 include dedicated output pins for, DVP\r\nCamera Interface, LCD Interface, and integrated temp sensor. If your project\r\nneeds even more peripherals, we have included a Qwiic connector on board for\r\neasy integration into any of SparkFuns Qwiic ecosystem equipped sensors and\r\naccessories. You will also find that this Thing Plus utilizes a USB-C\r\nconnector instead of the microB USB found on its predecessor. Keep in mind\r\nthat while the ESP32-S2 does include an Integrated 802.11 b\/g\/n WiFi\r\nTransceiver allowing for speeds up to 150Mbps, it lacks the Bluetooth\r\ncapabilities of the original ESP32 module. Additionally, the SRAM \u0026amp; ROM have\r\nbeen reduced.
