MCHPATWILC3000-MR110CA

Overview

The ATWILC3000-MR110CA is a combined IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.0 Low Energy (BLE) module designed for low-power IoT applications. It features an integrated chip antenna and a built-in power amplifier, making it a compact solution for adding wireless connectivity to an external host microcontroller via SPI or UART interfaces.

Why Choose This Part

This module offers superior sensitivity and range through advanced PHY signal processing and an integrated LNA. It simplifies system design by including the PA, LNA, and transmit/receive switch on-module while maintaining a very low shutdown current for power-sensitive applications.

Applications

Getting Started

To begin development, use the ATWILC3000-SHLD evaluation board which provides an Arduino-compatible header for easy connection to host MCUs like the SAM D21. Developers should use the Microchip Harmony 3 framework, which includes the necessary drivers and wireless stacks for both Wi-Fi and BLE operations.

Also Consider

ATWINC1500-MR210PB MCHPMicrochip Technology - If Bluetooth connectivity is not required, this Wi-Fi only module offers a smaller footprint and lower cost.

ESP32-WROOM-32E Espressif Systems - A more integrated alternative that includes a dual-core MCU, reducing the need for an external host processor.
