SAMD21 BREAKOUT开发板

enly

SparkFun SAMD21 Breakout开发板已经配备了一个用于编程和电源的USB接口，、RTC液晶，一个600毫安3.3V稳压器环绕其中。SMART SAMD21是基于32位ARM®Cortex®-M0+的低功耗微控制器，具有32~64个引脚并且Flash多达256KB、SRAM提升到32KB。SAMD21最大工作频率高达48MHz并且达到2.46Coremark/MHz。他们设计有高灵活性的相同外围模块，程序代码兼容，相同的线性地址映射和管脚匹配在产品系列的所有型号。The SparkFun SAMD21 Dev Breakout has been equipped with a USB interface for programming and power, surrounded with an RTC crystal, and a 600mA 3.3V regulator. By utilizing the Pro R3’s extra PCB real-estate we’ve been able to leave room for a few extra GPIO pins and an integrated LiPo charger. To power the SAMD21 Breakout board, just plug it into a USB port on your computer via the micro-B port on the breakout. Not near a USB port? No problem, the SparkFun SAMD21 Dev Breakout is also equipped with a LiPo Battery connector (for a single-cell 3.7-4.2V litium-polymer battery) and unpopluated supply input to solder on your own PTH Barrel Jack. If you’ve used any Arduino before, this pinout shouldn’t surprise you – the layout meets the Arduino 1.0 footprint standard, including a separate SPI header and additional I2C header.Features:
