It supports loads up to 5 kg and communicates with a compatible host at address 0x26, making it useful for ingredient scales, package checks, material dispensing, inventory bins, and force-measurement experiments. Accurate results require calibration with known weights, a rigid and level mounting platform, centered loading, overload protection, and temperature-aware measurement procedures.\u003c\/p\u003e\u003ch2\u003e5kg Load-Cell Measurement with the M5Stack Mini Scales Unit\u003c\/h2\u003e\u003ch3\u003eRead HX711 Weight Data over I2C\u003c\/h3\u003e\u003cp\u003eThe HX711 digitizes the load-cell signal while the onboard STM32F030F4P6 manages measurement and host communication through I2C address 0x26.\u003c\/p\u003e\u003ch3\u003eTare and Zero with the Onboard Button\u003c\/h3\u003e\u003cp\u003eThe local button can be used to establish a zero or tare reference, allowing the host to subtract a container or fixture before calculating the net load.\u003c\/p\u003e\u003ch3\u003eShow Stable, Tare and Overload States with RGB\u003c\/h3\u003e\u003cp\u003eThe SK6812 RGB LED can provide immediate feedback for startup, tare, stable reading, target range, overload, or communication errors.\u003c\/p\u003e\u003ch2\u003eM5Stack Mini Scales Unit Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIngredient and portion measurement prototypes\u003c\/li\u003e\n\u003cli\u003ePackage weight checking\u003c\/li\u003e\n\u003cli\u003eMaterial dispensing and filling systems\u003c\/li\u003e\n\u003cli\u003eSmart shelves and inventory bins\u003c\/li\u003e\n\u003cli\u003eForce and load-cell education\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to Integrate the M5Stack Mini Scales Unit\u003c\/h2\u003e\u003col\u003e\n\u003cli\u003eMount the unit securely using the M3 hardware and attach a rigid platform that does not contact the base or enclosure.\u003c\/li\u003e\n\u003cli\u003eConnect the Grove cable to a compatible I2C port and confirm that address 0x26 is available.\u003c\/li\u003e\n\u003cli\u003eRecord the unloaded zero value, then calibrate with one or more known reference weights.\u003c\/li\u003e\n\u003cli\u003eApply loads near the center of the platform and wait for the reading to stabilize before accepting the result.\u003c\/li\u003e\n\u003cli\u003eStore calibration data and define overload, drift, and sensor-disconnection handling in firmware.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch2\u003eM5Stack Mini Scales Unit Deployment Notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe stated 5 kg value is a maximum load reference, not a recommended continuous overload point.\u003c\/li\u003e\n\u003cli\u003eA weighing platform is not included and must be designed for centered, repeatable force transfer.\u003c\/li\u003e\n\u003cli\u003eMechanical preload, off-center loading, creep, vibration, temperature, and mounting stress affect accuracy.\u003c\/li\u003e\n\u003cli\u003eRecalibrate after changing the platform, enclosure, mounting hardware, or operating environment.\u003c\/li\u003e\n\u003cli\u003eThis development unit is not a certified trade scale or medical weighing instrument.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eM5Stack Mini Scales Unit Development Resources\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.m5stack.com\/en\/products\/sku\/U177\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eM5Stack Mini Scales Unit Official Documentation\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/uiflow2.m5stack.com\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eUiFlow2 Development Environment\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.arduino.cc\/software\/ide\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eArduino IDE\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LogicBoundless","offers":[{"title":"Default Title","offer_id":49240388042967,"sku":"LB-M5-U177","price":9.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/8952\/2135\/files\/1_68a2ffaf-75df-486f-a7ef-754881cce4b1.webp?v=1783243290","url":"https:\/\/logicboundless.com\/products\/m5stack-mini-scales-unit-hx711-5kg-i2c-u177","provider":"LogicBoundless","version":"1.0","type":"link"}
