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.

Vibrant, Rich Colors
This is my absolute FAVORITE sublimation ink. For the price, it's the best you'll find the canisters are easy to use, don't leak, and lasting for months. The bottles fit perfectly onto the eco tank. The colors are vibrant, rich, transferring to piece exactly as it should. These work like a dream and I'm a loyal customer, for sure.
