## Description

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). 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..All of that can sound a little daunting, but we assure you that the ESP32-S2 Thing Plus is anything but! 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.Additional new features of the ESP32-S2 include dedicated output pins for, DVP Camera Interface, LCD Interface, and integrated temp sensor. If your project needs even more peripherals, we have included a Qwiic connector on board for easy integration into any of SparkFuns Qwiic ecosystem equipped sensors and accessories. You will also find that this Thing Plus utilizes a USB-C connector instead of the microB USB found on its predecessor.Keep in mind that while the ESP32-S2 does include an Integrated 802.11 b/g/n WiFi Transceiver allowing for speeds up to 150Mbps, it lacks the Bluetooth capabilities of the original ESP32 module. Additionally, the SRAM & ROM have been reduced. However, the support for larger external storage should easily be able to compensate for this.

### ⭐⭐⭐⭐⭐ School
*by J***N on June 19, 2023*

I had to get this for a class in college. And if did the job!

### ⭐⭐⭐⭐ The ESP32-S2 doe NOT have Bluetooth
*by C***R on May 10, 2022*

I like the Sparkfun "thing" boards but the ESP32-S2 does not have bluetooth. Amazon needs to change this product description.

### ⭐ Does not work. No support at Sparkfun or Arduino.
*by T***F on November 30, 2022*

I've bought 3 ESP-32 from SparkFun via Amazon and directly from SparkFun. The ESP-32-S2 absolutely will not work on either Mac or Windows. Windows will not recognize it and on Mac OS using the Arduino IDE, The error message "This chip is ESP-S2 not ESP32. Wrong -- chip argument". I have pulled my hair out, installed drivers, tried to find support on forums but all I can find is that this is a huge problem. The ESP32 Thing Plus (also from SparkFun) required a lot of contortions to get it to work. I finally got it working by holding down the boot button (not the reset button) on the board while uploading the sketch and then unplugging the board and plugging it back in. Again, no support or info on this at SparkFun. The third SparkFun ESP32 Thing Plus can't be found by Arduino when using Mac or Windows. My recommendation is to stay away from SparkFunESP32 unless you love frustration, no support and an extremely high failure rate of products. I might try Adafruit or another ESP32 but I am done purchasing SparkFun boards and sensors.
