ESP32 WROOM Module v1.1 w/ PCB Antenna

Description

The ESP32 WROOM Module v1.1 is a highly integrated wireless microcontroller unit based on Espressif’s ESP32 chipset. It combines a dual-core processor with Wi-Fi 802.11 b/g/n and Bluetooth 4.2 BR/EDR & BLE connectivity, targeting a wide spectrum of IoT applications from simple sensor nodes to complex tasks like music streaming. The module’s RF front-end integrates the antenna switch, balun, power amplifier, and filters, minimizing external component count and PCB area.

Engineered for power efficiency, the ESP32 features fine-resolution clock gating, multiple power modes, and dynamic power scaling, enabling sleep currents below 5 microamps. This makes it ideal for perpetually powered devices. The module supports a broad 2.3V to 3.6V supply range and operates reliably across an industrial temperature span from -40°C to 90°C, ensuring stability in challenging conditions.
