WINC1500 Overview
ATWINC1500.png

The ATWINC15x0-MR210xB is a low power consumption 802.11 b/g/n IoT (Internet of Things) module, specifically optimized for low power IoT applications. The module integrates Power Amplifier (PA), Low-Noise Amplifier (LNA), Switch, Power Management, and a printed antenna or a micro co-ax (U.FL) connector for an external antenna resulting in a small form factor (21.7 x 14.7 x 2.1 mm) design.

This module is an ideal add-on to existing microcontroller (MCU) solutions bringing Wi-Fi® and network capabilities through an SPI-to-Wi-Fi interface. The WINC1500 connects to any SAM, 24-bit and 32-bit PIC® MCUs with minimal resource requirements.
