SparkFun Thing Plus ESP32-S2 WROOM Development Board - WiFi Feather Board With USB-C

About This Product

Hey makers and IoT enthusiasts! This SparkFun Thing Plus ESP32-S2 board is seriously impressive for your connected projects. It's built around the ESP32-S2 WROOM module with a single-core 32-bit LX7 processor that can crank up to 240MHz, plus there's a RISC-V ULP coprocessor for those power-sensitive applications. You get 4MB of embedded flash storage and 320KB SRAM to work with. The security features are way better than older ESP boards - we're talking transparent flash/RAM encryption, secure boot that only runs signed firmware, and hardware crypto acceleration for AES, SHA, RSA, and ECC. The 2.4GHz WiFi is solid with speeds up to 150Mbps, though fair warning - there's no Bluetooth on this one. What's really handy is the Feather form factor with USB-C connector, LiPo charging circuit, and Qwiic connector for easily adding sensors. You've got 21 GPIO pins to play with including 16 ADC channels, touch sensors, camera interface, and all the standard peripherals. Perfect for home automation, wearables, or any project where you need reliable WiFi connectivity with enterprise-level security. The power consumption is pretty efficient too - from 310mA peak down to just 20-235??A in deep sleep mode. If you're stepping up from ESP8266 or want better security than the original ESP32, this board is absolutely worth checking out for your next connected project!
