SAMD21 Mini Breakout

如果您準備好從舊的8位/ 16MHz微控制器提高Arduino遊戲的性能,SparkFun SAMD21 Mini Breakout是一個不錯的選擇。SAMD21 Mini Breakout是適用於Atmel ATSAMD21G18、32位ARM Cortex-M0 +處理器,具有256KB閃存,32KB SRAM和最高48MHz的運行速度的Pro小型突破口。這個小型突破為您提供了一個Arduino硬件選項,該選項解決了困擾Arduino系列先前迭代的低存儲限制和動態內存堆棧溢出的問題。是的,甚至在Arduino IDE和Arduino Zero的庫中也完全支持SparkFun SAMD21 Mini Breakout!

SparkFun SAMD21 Mini Breakout配備了用於編程和供電的USB接口,並帶有RTC晶體和600mA 3.3V穩壓器。通過利用Pro R3的額外PCB面積,我們能夠為一些額外的GPIO引腳留出空間。我們已經將Mini Breakout固定為盡可能匹配我們忠實的Pro Mini和Pro Micro。I / O和電壓​​軌均分為一對兼容麵包板的接頭連接器。通過micro-B USB連接器可以供電,並且可以對電路板進行編程。

SAMD21的最獨特功能之一是SERCOM –一組六個可配置的串行接口,可以轉換為UART,I 2 C主設備,I 2 C從設備,SPI主設備或SPI從設備。每個SERCOM都提供了很大的靈活性:端口可以復用,您可以選擇分配每個引腳的任務。

SAMD21 Mini Breakout

If you’re ready to step your Arduino game up from older 8-bit/16MHz microcontrollers, the SparkFun SAMD21 Mini Breakout is a great landing spot. The SAMD21 Mini Breakout is a Pro Mini-sized breakout for the Atmel ATSAMD21G18, a 32-bit ARM Cortex-M0+ processor with 256KB flash, 32KB SRAM, and an operating speed of up to 48MHz. This mini breakout provides you with an Arduino hardware option that solves the problems of low storage limits and dynamic memory stack overflows that have plagued the previous iterations of the Arduino family. Yes, the SparkFun SAMD21 Mini Breakout is even fully supported in the Arduino IDE and libraries for the Arduino Zero!

The SparkFun SAMD21 Mini 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. We’ve pinned the Mini Breakout to match – as much as possible – our faithful Pro Mini and Pro Micro. The I/O and voltage rails are all broken out to a pair of breadboard-compatible headers. Power can be supplied, and the board can be programmed, through the micro-B USB connector.

One of the most unique features of the SAMD21 is SERCOM – a set of six configurable serial interfaces that can be turned into either a UART, I2C master, I2C slave, SPI master, or SPI slave. Each SERCOM provides for a lot of flexibility: the ports can be multiplexed, giving you a choice of which task each pin is assigned.

The on-line SAMD21 Mini/Dev Breakout Hookup Guide (in the Documents section below) contains step by step instructions of how to connect your SparkFun SAMD21 Mini Breakout as well as a few circuit examples to test out. Full example code is provided and explained and even includes troubleshooting tips to make make you have zero problems.

Note: The breakout does NOT have headers installed and will need to purchased and soldered on yourself. Check the Recommended Products section below for the type of headers we use in the Hookup Guide!
