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: * ESP32-S3 Mini Module: * Dual-Core Xtensa® 32-bit LX7 Processor * 45 Programmable GPIO (21 pins broken out on Thing Plus, 17 analog input capable) * Up to 3 UART Channels * 1 Full-Speed USB OTG * 1 USB Serial/JTAG Controller * Up to 4 SPI * Up to 2 I²C * Up to 2 I²S * 1 LCD Interface * Up to 8 LED PWM Controller Channels * 1 TWAI® Controller (Compatible with ISO 11898-1 CAN Spec. 2.0) * 4 MB Flash * 2 MB PSRAM * 2.4 GHz WiFi 6 * Bluetooth® 5 LE * PCB Antenna * Thing Plus Form-Factor: * Dimensions: 6.48 cm x 2.29 cm * Two Mounting Holes * 28 PTH pins * USB-C Connector * 2-pin JST Connector for LiPo Battery (not included) * 4-pin Qwiic Connector * microSD Card Slot * MCP73831 Battery Charger * Charge Rate: 213mA@3.3V * MAX17048 Fuel Gauge * I²C Address: 0x36 * LEDs: * PWR - Red Power LED * CHG - Yellow Battery Charging Indicator * STAT - Blue LED * WS2812 - RGB LED (Data In tied to ESP46) * Buttons: * BOOT * RESET Documents: * Schematic * KiCad Files * Board Dimensions * Hookup Guide * Datasheet (ESP32-S3 MINI-1) * Thing Plus Info Page * Qwiic Info Page * GitHub Hardware Repo https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-01-24 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-09-28 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-10-10 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-10-19 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-10-21 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-10-31 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-11-02 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-11-12 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-11-22 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-11-30 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-12-03 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-12-05 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-12-13 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-12-19 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2025-12-27 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-01 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-12 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-23 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-25 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-28 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-01-31 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-02-03 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-02-05 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-02-11 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-02-19 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-03 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-05 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-10 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-15 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-19 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-03-22 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-04-13 https://elecena.pl/product/27751495/sparkfun-thing-plus-esp32-s3 2026-04-15
