timed switching + screen display + boost output\". It features an embedded STM32 microcontroller for implementing RTC (Real-Time Clock) and overall control, allowing users to set automatic power-on and power-off times according to their needs.\u003c\/p\u003e\n\u003cp\u003eThe unit is \u003cstrong\u003epowered\u003c\/strong\u003e via a \u003cstrong\u003eType-C\u003c\/strong\u003e interface and can be connected to a rechargeable battery through a 1.25-2P interface. It includes a built-in battery charging circuit that supports a charging current of 330mA. Additionally, it features a built-in DC-DC \u003cstrong\u003eboost\u003c\/strong\u003e circuit, which can provide a 5V\/800mA (1400mA@1C battery-powered) power output to external devices through the Grove port. Moreover, it includes an INA3221 sensor for real-time monitoring of input and output current and voltage.\u003c\/p\u003e\n\u003cp\u003eThis unit is equipped with a 0.66-inch \u003cstrong\u003eOLED\u003c\/strong\u003e display and two side buttons for user interaction, enabling users to easily view the system's real-time status and modify settings. Users can configure settings using the side buttons or via I2C commands through the Grove interface. This product is suitable for applications such as smart homes, industrial automation, and timed control devices.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRTC cyclic timing control\u003c\/li\u003e\n\u003cli\u003eBattery-powered\u003c\/li\u003e\n\u003cli\u003eBuilt-in DC-DC boost circuit\u003c\/li\u003e\n\u003cli\u003eCurrent\/voltage monitoring\u003c\/li\u003e\n\u003cli\u003eOLED display\u003c\/li\u003e\n\u003cli\u003eGrove interface\u003c\/li\u003e\n\u003cli\u003eButton-controlled power on\/off mode\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit TimerPWR\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTimed control devices\u003c\/li\u003e\n\u003cli\u003ePortable electronic devices\u003c\/li\u003e\n\u003cli\u003eSensor node power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameters\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTM32G031G8U6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003eSupports 5V DC input (via Type-C interface)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003eBuilt-in DC-DC boost circuit, outputs 5V for external devices\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Power\u003c\/td\u003e\n\u003ctd\u003e3.7V polymer lithium battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e0.66-inch OLED display, 64x48 resolution, SPI communication\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterfaces\u003c\/td\u003e\n\u003ctd\u003eType-C interface: for battery charging (cannot directly power the Grove port) \u003cbr\u003eGrove interface: for external sensors and module expansion, supports communication and external power supply\u003cbr\u003eBattery interface: 1.25mm@2P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI2C Communication Address\u003c\/td\u003e\n\u003ctd\u003e0x56\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Sensor\u003c\/td\u003e\n\u003ctd\u003eINA3221\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharging Current\u003c\/td\u003e\n\u003ctd\u003eDC 5V@330mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharging Chip\u003c\/td\u003e\n\u003ctd\u003eLGS4056H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharging Temperature\u003c\/td\u003e\n\u003ctd\u003e55°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrove Port Max Output Current\u003c\/td\u003e\n\u003ctd\u003eRelated to battery capacity and discharge capability, e.g.:\u003cbr\u003e1400mAh@1C 3.7V:DC4.96V@800mA\u003cbr\u003e500mAh@1C 3.7V: DC4.97V@700mAh\u003cbr\u003e110mAh@1C 3.7V: DC5.03V@400mAh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003eDC4.2V@36.67uA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 ~ 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e40.0 x 24.0 x 11.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e7.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e138.0 x 93.0 x 12.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e13.2g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background: #fff8e1; border: 1px solid #ffe0a3; border-left: 4px solid #f9a825; border-radius: 8px; padding: 14px 16px; margin: 24px 0;\"\u003e\n\u003cstrong style=\"display: block; color: #8d6e00; font-size: 15px; margin-bottom: 6px;\"\u003e Power Supply Requirements: \u003c\/strong\u003e \u003cspan style=\"color: #2c2c2c; font-size: 14.5px; line-height: 1.6;\"\u003e When using the Unit TimerPWR, it must be connected to a lithium battery.
