ATWILC1000-SD Evaluation Kit

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.
