Adafruit TinyS3[D] ESP32-S3 by Unexpected Maker

The TinyS3[D] offers the compact power of the ESP32-S3 in a TinyPICO format, featuring dual antenna options—built-in and u.FL—for flexible connectivity. Easily swap antennas via RF switch within your code without risking ESP32-S3 damage.

Loaded with dual 32bit Xtensa LX7 cores at up to 240MHz, the TinyS3 supports CircuitPython, Arduino 2.0.3+, and ESP-IDF, providing various coding options. The onboard USB-C connector, LiPo charging pads, and deep sleep mode make it ideal for efficient development.

With 8MB QSPI Flash, 8MB extra QSPI PSRAM, Bluetooth® LE 5, and mesh network capabilities, it delivers advanced performance in a tiny package. Effortless updates and coding ease are achieved with the UF2 bootloader and USB Serial JTAG connection.

Benefiting from features like low power RGB LED, 17 GPIO, and the NEW I2C Battery Fuel Gauge, TinyS3[D] ensures versatile utility akin to its esteemed TinyPICO and TinyS2 siblings, making it an adept choice for the innovative developer.
