Chain ToF is a laser ranging sensor node in the M5Stack Chain series. The device integrates a VL53L0C laser ranging module, supporting a ranging range of 3~200cm with a measurement accuracy of ±3%. It is suitable for short-distance air-to-air ranging or object proximity detection applications.Chain ToF integrates an STM32G031G8U6 core controller and uses a UART serial cascading communication protocol. Through two HY2.0-4P expansion interfaces, it can expand to include more Chain series devices, building richer interactive applications.FeaturesFor M5Stack Chain SeriesVL53L0C Laser Ranging Module3~200cm Ranging RangeSTM32G031G8U6 Core ControllerUses UART Serial Cascading Communication Protocol2x HY2.0-4P Expansion Interfaces, expandable to Chain series devicesParameters:MCU: STM32G031G8U6Laser Ranging Module: VL53L0CRanging Range: 3~200cmRanging Accuracy: ±3%Input Power: DC 5VCommunication Interface: UARTInterface Specifications: 2x HY2.0-4PRGB LED: 1x WS2812CPower Consumption:Stop Mode (White RGB On): DC 5V@21.27mADefault Mode Single Ranging: DC 5V@20.26mADefault Mode Continuous Ranging: DC 5V@24.75mAOperating Temperature: 0~40℃Color: GrayMaterial: plasticPackage Contents:1 * Chain ToFOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
