EV74A47A

EV74A47A is a WILCS02 Wi-Fi Link controller SD board. This is a Secure Digital (SD) card interface board that supports the 2.4GHz IEEE® 802.11 b/g/n standard. It is designed to demonstrate the features and functionalities of Microchip’s low-power Wi-Fi WILCS02PE module. The WILCS02-SD board is a plug-in board containing the low-power WILCS02PE module. This board can be plugged in to any host Microprocessor (MPU) board with SD/MMCplus card connector support. This is targeted for an MPU host running a Linux OS and can be interfaced through the SDIO interface. The WILCS02-SD board has an on-board PTA interface header for the co-existence of the external Bluetooth® device. It supports a wide range of IoT applications such as home and industrial automation, remote equipment monitoring, health and fitness monitoring.

• SD/MMCplus card CONN for controlling the WILCS02PE module by host MPU board using SDIO interface
• On-board USB-to-UART converter using Microchip MCP2221A for debug UART
• Manual reset button to reset the WILCS02PE module
• Separate current measurement headers for VDD and VDDIO supply rails
• Power supply from a host MPU board through an SD/MMCplus CONN or test the PC using USB Type-C® cable
• 802.15.2 compliant 3-Wire PTA interface to support Wi-Fi®/Bluetooth® co-existence via shared antenna
• A good solution for adding Wi-Fi to an existing MPU through a SDIO interface
• A small, low-cost form factor that connects to host boards with via a SD/MMC
• An easy-to-use platform to speed up design concepts to market
