TM1652 是一款LED（发光二极管、数码管、点阵屏）驱动控制专用芯片，内部集成了数字通讯电路、 解码电路、数据锁存器、震荡器、LED驱动电路。通讯方式采用异步串口通信（UART）协议，因芯片只 接收单片机发来的数据，仅需要单片机的一个TX端口发送数据给芯片即可，实现单线通讯；在显示驱动 方面，芯片采用动态扫描方式，两种显示模式可选，8级段驱动电流可调，16级位占空比可调；TM1652 内置消隐处理优化电路。(TM1652 is an LED (light-emitting diode, LED, dot-matrix screen) driver control ASIC, integrated digital communications circuits, Decoding circuit, data latch, oscillator, LED driver circuit. Communication using asynchronous serial communication (UART) protocol, because the chip only MCU receives data sent only need a microcontroller TX port to send data to the chip can achieve single-wire communication the display driver Aspects, chip dynamic scan mode, two display modes, 8 segment drive current is adjustable, 16-bit adjustable duty cycle TM1652 Built-in blanking processing optimization circuit.)

说明：  智能台灯可以根据光照的亮度自动调节亮度，可以保护大人和孩子的视力。(Intelligent desk lamp can automatically adjust the brightness according to the brightness of light, which can protect the eyes of adults and children.)

智能追踪小车，并且可以用遥控手动控制转弯加前后左右(Intelligent tracking car, and can be controlled manually with the remote turn around Canada)

SGA芯片bootloader，可以驱动网口、内存、spiflash( SGA chip bootloader, can drive the network port, memory, spiflash)
