Recommended Essentials:
Take your next compact IoT build further with TinyS3[D] - an ESP32-S3 development board that pairs flexible radio options with maker-friendly power and I/O.
Switch between the onboard 3D high-gain antenna and a u.FL external antenna in firmware, then prototype fast with native USB, battery charging and plenty of GPIO on a board smaller than your thumb. From low-power sensor nodes to USB projects and wireless prototypes, TinyS3[D] gives you WiFi and Bluetooth LE 5 connectivity, CircuitPython out of the box, and a clean path to ESP-IDF, Arduino, MicroPython or PlatformIO when your project requires.
