# ESP32-WROOM-32UE-N16 (Component) ## Description 2.4GHz -98dBm SMD,19.2x18mm RF Transceiver Modules and Modems RoHS The ESP32-WROOM-32UE-N16 is a 2.4 GHz wireless MCU module built around the ESP32 SoC. It combines a dual-core processor, integrated Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 (Classic + BLE), along with rich peripherals. The “UE” variant specifically uses a U.FL / IPEX connector for an external antenna, making it ideal for applications that require better RF performance or flexible antenna placement (e.g., enclosed products or long-range communication). The “N16” indicates 16 MB external flash memory, suitable for large firmware, OTA updates, and data-heavy applications. Processing Dual-core Xtensa LX6 32-bit CPU Clock speed up to 240 MHz Memory 16 MB Flash (N16 variant) ~520 KB SRAM + 448 KB ROM Connectivity Wi-Fi: 802.11 b/g/n (up to 150 Mbps) Bluetooth: v4.2 (BR/EDR + BLE) Frequency: 2.4 GHz band Antenna External antenna via U.FL connector Better range and flexibility vs PCB antenna Interfaces / Peripherals GPIO (≈26 usable pins) UART, SPI, I2C, I2S, SDIO ADC, DAC PWM (LED & motor control) Capacitive touch sensing Security Hardware encryption: AES, SHA, RSA Secure boot & flash encryption support Power Operating voltage: 3.0V – 3.6V (typ. 3.3V) Multiple low-power modes for battery applications Environmental Operating temperature: -40°C to +85°C Physical Surface-mount module (~38 pins / 52 pads depending on reference) Compact and RF-shielded design Typical Applications Smart home devices (IoT) Industrial automation Wireless sensors and data loggers Wearables and consumer electronics Remote monitoring systems #Module #ESP32 ## Component Details - **Owner:** lcsc - **Created:** 10/31/2024 - **Last Updated:** 5/4/2026 - **Visibility:** Public - **Manufacturer Part Number:** ESP32-WROOM-32UE-N16 - **Part Type:** Module - **Manufacturer Name:** ESPRESSIF(乐鑫) - **JLCPCB Part Class:** Extended Part - **Datasheet URL:** https://www.lcsc.com/datasheet/C701346.pdf?spm=wm.sxq.inf.ggs___wm.ssy.bg.0.xh&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNRQFheUFNRR1hXUTsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Symbol Style:** parametric-v1 - **LCSC Part Number:** C701346 - **Package or Case Code:** WIFI-SMD_ESP32-WROOM-32UE - **Used in:** 28 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
