SparkFun Thing Plus - ESP32-S3

The SparkFun ESP32-S3 Thing Plus is a powerful and versatile IoT development platform featuring the ESP32 WROOM-S3 MINI wireless module from espressif™. Built around an Xtensa® 32-bit LX7 processor, it operates up to 240 MHz and supports 2.4 GHz WiFi and Bluetooth® 5 (LE) with a built-in PCB antenna. It includes 4MB Flash memory, 2MB PSRAM, and a microSD card slot for additional storage.This module boasts numerous peripherals such as UART, I²C, SPI, LCD control, SDIO host, and a TWAI® controller (compatible with ISO 11898-1, CAN Specification 2). The ESP32-S3 can run two USB ports simultaneously and can act as a USB host device, providing extensive flexibility for various applications.The Thing Plus footprint breaks out 21 of the ESP32-S3's GPIO pins, including six analog-capable pins, along with Reset and Enable signals to a pair of 2.54mm-spaced plated through hole (PTH) headers. These GPIO pins are available for UART, I²C, and SPI interfaces, making it easy to connect to other devices and sensors.Equipped with a USB-C connector for power and programming, a 2-pin JST connector for a LiPo battery (not included), a microSD card slot for expanded storage, and a Qwiic connector, this board integrates seamlessly into SparkFun’s Qwiic ecosystem. It also features a charging circuit and fuel gauge for monitoring an attached LiPo battery.The SparkFun Qwiic Connect System simplifies prototyping by using a common 1mm pitch, 4-pin JST connector. This reduces PCB space requirements and ensures correct connections with polarized connectors.Features:
