Microchip Technology ATWILC3000 SD Card Evaluation Kit

Microchip ATWILC3000 SD Card Evaluation Kit includes a WILC3000 SD card interface board that supports IEEE^® 802.11 b/g/n standard and Bluetooth^® Low Energy (BLE) 5.0. This Microchip extension board is designed to demonstrate the features of the low-power consumption ATWILC3000-MR110CA IoT module. The WILC3000 board can be connected to any host microcontroller board with Secure Digital Input/Output (SDIO) or Multimedia Card plus (MMCplus). This connection is established via an onboard MMCplus card connector using either SDIO/SPI for controlling Wi-Fi. The BLUETOOTH® UART is connected to the host microcontroller using the Bluetooth header for controlling the Bluetooth of the ATWILC3000 module.
