VA Meter is a professional programmable high-precision power meter designed for accurate voltage and current measurement. This product is based on the M5StampS3 main control module, supporting WiFi functionality. It features two serially connected INA226 current and voltage measurement circuits, providing current detection resolutions of 2.5uA and 250uA, and supports a measurement range of 0-5A and 5-24V (1-24V in isolation mode). The product can be powered through a USB-C interface or Base terminal input and includes built-in power and signal isolation. Users can select between isolated measurement via USB power or non-isolated measurement using direct power through a toggle switch, catering to different application needs. The accompanying expansion BASE includes relay on/off control and a Grove port for secondary development.
