This reference design for a 6A step-down LED driver is based on the MAX16821 device. This circuit drives a single LED. This design includes the circuit specifications, circuit schematic, and circuit description and performance.
Genesis One uses STM32F103RCT6 as the main control, integrating lithium battery charge and discharge management, voltage stabilization, Bluetooth serial port HID, USB-HID, LED light array driver, and button detection circuit. It can realize Bluetooth connection mode (supports IOS, Android and other platforms) and USB connection mode. The response time of Bluetooth connection is about 15ms, and the response time of the master control in USB connection mode is about 0.3Ms.

This article introduces the framework structure and component modules of the design as well as the principles of each module. It also introduces the hardware design of each part, the software design of each part, and the software flow chart. The design is an intelligent LED desk lamp integrating multiple functions with STC89C52 microcontroller as the control core. The desk lamp realizes the function of automatically detecting whether there is someone in the room and automatically turning on/off; the desk lamp brightness has an adjustment function; it has a time display function; it has a temperature display function; and it has an alarm function. The hardware design is divided into eight parts, including the microcontroller control module, button module, desk lamp module, temperature module, clock module, alarm module, display module, and infrared sensing module. The microcontroller control uses STC89C52, the display module uses LCD1602C liquid crystal to display temperature, time, date, etc., the button module is used to adjust time, date, LED brightness, etc., the clock uses DS12C887 clock chip, and the desk lamp module uses 16 LEDs and uses a buzzer. The device emits an alarm sound, the temperature sensor uses a DS18B20 chip, and the human detection device uses a BIS0001 infrared thermal sensor. The software design is written in microcontroller C language and realizes all control functions.
The add-on kit for the NTAG I²C+ Explorer Kit (Interconnected NFC Tag) contains Category 4, Category 5 and Category 6 Flex antennas.
