ST STEVAL-ILL022V1 80W太阳能充电器和25W LED街灯照明解决方案
ST公司的STEVAL-ILL022V1是采用STM32F101Rx MCU的80W太阳能充电器和25W LED街灯照明解决方案.太阳能街灯控制器包括80W 电池充电器和25W LED驱动器.在白天有足够太阳光,充电器从太阳能电池板多电池充电,在晚上,电池为LED街灯提供能量.如果连续几天是雨天或多云天气,控制器采用AC火线给LED供电,直至电池有足够时间充满电.本文介绍了32位STM32F101x4 和STM32F101x6 MCU主要特性,方框图, 太阳能LED街灯控制器主要特性,系统方框图,电路图和材料清单.
The STM32F101x4 and STM32F101x6 Low-density access line family incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 36 MHz frequency, high-speed embedded memories (Flash memory of 16 to 32 Kbytes and SRAM of 4 to 6 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (one I2C, one SPI, and two USARTs), one 12-bit ADC and up to two general-purpose 16-bit timers.
The STM32F101xx Low-density access line family operates in the –40 to +85 ℃ temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
