Overview

The ATWINC1500-MR210UB1954 is a low-power IoT network controller module optimized for adding 802.11b/g/n Wi-Fi connectivity to embedded systems. It features an integrated 32-bit Cortus APS3 processor, a full TCP/IP protocol stack, and 512KB of flash memory to offload networking tasks from a host microcontroller. This specific variant includes a U.FL connector for an external antenna and a chip antenna, providing flexible RF design options.

Why Choose This Part

It significantly reduces host MCU overhead by handling the entire network stack including DHCP, ARP, and TCP/UDP sockets on-module. The module offers superior sensitivity of -95dBm and high output power of 18.5dBm, ensuring a robust wireless link in challenging environments.

Applications

Battery-Powered IoT Sensors
Utilizes a 4uA Deep Sleep mode and an integrated power amplifier to maintain long battery life while providing reliable data transmission.
Smart Home Appliances
Enables remote control and monitoring via integrated SSL, DNS, and HTTP support for secure cloud connectivity.
Industrial Gateway Bridges
Acts as a Wi-Fi bridge for legacy industrial equipment using SPI or UART interfaces to transmit sensor data to the local network.
