Microchip’s ATWILC1000-SD evaluation kit is a hardware platform to evaluate the ATWILC1000-MR110PB module. The ATWILC1000-SD is based on the SmartConnect WILC1000, an IEEE 802.11 b/g/n IoT (Internet of Things) link controller module. It is the ideal add-on to existing MCU solutions bringing Wi-Fi through UART or SPI/SDIO-to-Wi-Fi interface. The WILC1000 connects to any AVR or SMART MCU with minimal resource requirements. The WILC1000 most advanced mode is a single stream 1x1 802.11n mode providing up to 72 Mbps PHY throughput. WILC1000 features a fully integrated power amplifier, LNA, switch, and power management. The WILC1000 provides multiple peripheral interfaces, including UART, SPI, SDIO, and I²C. The only external clock source needed for the WILC1000 is a high-speed crystal or oscillator with a wide variety of reference clock frequencies supported (between 12 MHz and 32 MHz).

The ATWILC1000-MR110xB module is a low-power consumption IEEE 802.11 b/g/n IoT module, which is specifically optimized for low-power IoT applications. The ATWILC1000-MR110xB modules feature small form factor (21.7 mm x 14.7 mm x 2.1 mm) while fully integrating power amplifier (PA), low noise amplifier (LNA), transmit/receive (T/R), switch, and power management. The ATWILC1000-MR110PB includes a PCB antenna while the ATWILC1000-MR110UB module includes a u.FL connector to use with an external antenna. With advanced security, it is interoperable with various vendors using IEEE 802.11b/g/n access points in wireless LAN. The rich feature set of the ATWILC1000-MR110xB Wi-Fi module makes it suitable for any low-power IoT application.
