Product Overview

The SparkFun ESP32 Thing Plus (U.FL) is the perfect foundation for your Internet of Things projects that require specific or unique antennas. Powered by the ESP32-WROOM-32UE module from Espressif™, this board provides a scalable environment for your wireless applications. The module features an Xtensa® Dual-Core 32-bit LX6 microprocessor running at up to 240MHz, along with 16MB of embedded Flash storage and 520KB of internal SRAM.

This board provides reliable wireless communication tailored for custom installations and challenging environments:

WiFi (802.11b/g/n): Dependable 2.4GHz transceiver for local network and cloud connectivity.
Dual-Mode Bluetooth®: Support for both Classic Bluetooth and Bluetooth Low Energy (BLE).
Hardware Encryption: Built-in acceleration for AES, SHA2, ECC, and RSA-4096 to keep your data secure.

While this board is nearly identical to our micro-B version, the inclusion of a U.FL connector on the ESP32 module lets you attach your own external antenna rather than relying on the fixed PCB trace typically found on Espressif's SoCs. This is particularly beneficial when your project is housed inside a metal enclosure or requires an extended wireless range that only a specialized external antenna can provide.
