Microchip's WINC1510 is a low-power consumption 802.11 b/g/n IoT 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 (21.7x14.7x2.1 mm) design. It is interoperable with various vendors’ 802.11 b/g/n access points. This module provides SPI ports to interface with a host controller.
WINC1510 provides internal Flash memory as well as multiple peripheral interfaces, including UART and SPI. The only external clock source needed for WINC1510 is the built-in, high-speed crystal or oscillator (26 MHz). WINC1510 is available in a QFN package or as a certified module.
The communication interface between the ATmega4808 and the WINC1510 Wi-Fi module is SPI, together with some enable signals and interrupt. The rest of the connections are left unconnected.
