Description
Description VAMeter is a professional, programmable, high-precision power meter designed for accurate voltage and current measurements. Powered by the Stamp-S3 module, it features Wi-Fi connectivity and two cascaded INA226 current/voltage sensing circuits, delivering current detection resolutions of 2.5 µA and 250 µA. The measurement range supports 0-5 A and 5-24 V (1-24 V in isolation mode). The device offers flexible power-supply options through the USB-C port or the Base terminal, with built-in power and signal isolation. A slide switch lets users choose between isolated measurements powered via USB and non-isolated measurements powered directly from the test source, meeting various application needs. The included expansion BASE provides relay on/off control and a Grove port for secondary development. Additional features include OTA firmware upgrades and USB MSC/OTG support, allowing users to view and edit data and configuration files stored in the main controller’s file system from a PC. M5Stack also supplies a free online data API for uploading test data to the EZData platform, enabling remote access and visualization and greatly simplifying IoT application development. VAMeter is a highly practical and developer-friendly instrument, ideal for projects requiring precise current and voltage measurements, as well as for industrial automation, equipment monitoring, smart grid, and related fields.
