EV24U22A

EV24U22A is a MTCH9010 evaluation kit designed to help users quickly familiarize themselves with the MTCH9010 capabilities. The kit includes capacitive and conductive sensor boards and uses an MCP2221A USB-to-UART bridge for sensor data streaming and device configuration through the MTCH9010 Enhanced Configuration Mode. The evaluation kit is designed to allow users to easily interface and test their own custom sensors with the MTCH9010, providing a versatile platform for rapid development and experimentation.

• Liquid detection and indication: includes capacitive and conductive sensor boards
• Detect LED indicates liquid detection, heartbeat LED provides system status updates
• Configure MTCH9010 using slide switches or UART: easy configuration using the slide switches
• Selectable capacitive or conductive sensing modes, enable sensor data streaming
• Enable enhanced configuration mode, adjustable liquid detection threshold via potentiometer
• Selectable sleep periods to optimize power consumption
• Configuration using UART interface: access enhanced settings for more precise control, customization
• MCP2221A USB to UART bridge for easy data logging and communication
• On-board status LED indicating successful enumeration with host computer
• Directly power the board via USB for easy use, on-board LDO ensures stable 3.3V operation
