您是工程师，制造者还是学生？
无论你在电子发烧友频谱上的哪个位置，优秀的均衡器都是成本。
每个人都希望获得最好的“爆炸”。
Digi-Key为您提供三个开发板，不会破坏银行。
16美元，以Micro：bit让他们早点开始
微：MBIT0004位
来自Pimoroni的micro：bit是一个令人难以置信的用户友好型开发平台。
这款袖珍型电路板尺寸为4厘米×5厘米，包含运动检测功能，内置指南针，内置蓝牙和LED显示屏。
入门级制作人员和小学生将从拖放式编程界面中获益。
除了直观的界面之外，micro：bit还有一个功能齐全的支持网站，其中包含项目，想法和课程（奖励：它们是免费的）。
micro：bit可以连接到其他设备，传感器，套件和对象。
它是Arduino，Galileo，Kano，littleBits和Raspberry Pi的伴侣，为其他更复杂的平台的未来发展提供了一个跳跃点。
用Arduino Uno板以24美元的价格磨练你的技能
Arduino Uno A000066
Arduino Uno是我们网站上最畅销的Arduino板，是制造商社区的最爱。
基于ATmega328，Arduino Uno具有14个数字I / O引脚（可选6个PWM输出），6个模拟输入，16 MHz晶振，USB连接和电源插孔以及其他功能。
Uno包含支持ATmega328开发所需的一切;
只需将它连接到计算机，启动它，然后就可以了。
Uno使用Arduino IDE（可用的在线或桌面版本）和Arduino编程语言（基于连线）。
由于Arduino Uno在线广泛支持开源项目和示例代码，因此入门应该是轻而易举的。
25美元，使用PocketBeagle最大化您的设计
口袋比格犬POCKETBEAGLE-SC-569
最新的Beagle Board被称为PocketBeagle，这是有充分理由的。
这款超小而又完整的开源USB钥匙扣式计算机适合......放在口袋里。
PocketBeagle以专业工程师和初级制造商为目标，是一款低成本，易于使用的Linux计算机，具有无限的可扩展性。
PocketBeagle的大脑是Octavo Systems OSD3358-SM系统级封装，包括512MB DDR3内存，1 GHz ARM Cortex-A8 CPU，2x 200 MHz PRU，ARM Cortex-M3，3D加速器，电源/电池管理，
和EEPROM。
最重要的是，该板本身包含72个带电源和电池I / O的扩展引脚接头，高速USB，8个模拟输入，44个数字I / O和大量数字接口外设。
板上的标准连接器包括microUSB（主机/客户端）和microSD。
与Arduino支持社区类似，Beagleboard.org以开源项目和在线编程教育支持的形式提供支持。
适合所有人的董事会
尽早向孩子们介绍编程可以让他们获得批判性思维技能，从而转移到生活中的任何事情。
如此低的初始投资，这三个开发平台中的任何一个都是开始使用电子产品的好地方。
或者您可能对项目有所了解，但您现有的电路板已经使用 - 只需几杯咖啡，您就可以在工具箱中添加另一杯咖啡。

Are you an Engineer, Maker, or Student? Regardless of where you fall on the electronic enthusiast spectrum, the great equalizer is cost. Everyone is looking to get the best “bang” for their buck. Digi-Key has you covered with three development boards that won’t break the bank.
Get them started early with the Micro:bit for $16
![]() micro:bit MBIT0004
![]()
The micro:bit from Pimoroni is an incredibly user friendly development platform. Measuring 4 cm by 5 cm, this pocket-sized board contains motion detection features, a built-in compass, built-in Bluetooth, and an LED display. Entry-level makers and elementary school students will get a kick out of the drag-and-drop programming interface. On top of its intuitive interface, micro:bit has a full featured support website with projects, ideas, and lessons (Bonus: they’re free).
The micro:bit can connect to other devices, sensors, kits and objects. It is a companion to Arduino, Galileo, Kano, littleBits, and Raspberry Pi, providing a jump off point for future development with other more complex platforms.
Hone your skills with the Arduino Uno board for $24
![]() Arduino Uno A000066

The best-selling Arduino board on our site, the Arduino Uno is a favorite in the maker community. Based on the ATmega328, the Arduino Uno has 14 digital I/O pins (with an option for six PWM outputs), six analog inputs, a 16 MHz crystal oscillator, USB connection and power jack in addition to other features. The Uno contains everything needed to support development with the ATmega328; just connect it to a computer, power it up, and you’re off.
The Uno uses the Arduino IDE (online or desktop versions available) and the Arduino programming language (based on Wiring). Since the Arduino Uno is widely supported online with open source projects and example code, getting started should be a breeze.
Maximize your design with the PocketBeagle for $25

The latest Beagle Board has been dubbed the PocketBeagle and for good reason. This ultra-tiny yet complete open-source USB-key-fob computer fits…well…in your pocket. Targeting professional engineers and beginning makers alike, the PocketBeagle is a low-cost and easy-to-use Linux computer with endless expansibility.
The brain of the PocketBeagle is the Octavo Systems OSD3358-SM system-in-package which includes 512MB of DDR3 RAM, 1 GHz ARM Cortex-A8 CPU, 2x 200 MHz PRUs, ARM Cortex-M3, 3D accelerator, power/battery management, and EEPROM. On top of that the board itself contains 72 expansion pin headers with power and battery I/Os, high-speed USB, eight analog inputs, 44 digital I/Os, and a plethora of digital interface peripherals. Standard connectors on the board include a microUSB (host/client) and microSD.
Similar to the Arduino support community, Beagleboard.org offers support in the form of open source projects and online programming education support.
Boards for Everyone
Introducing children to programming early gives them critical thinking skills that transfer to anything they do in life. With such a low initial investment, any of these three development platforms is a great place to start with electronics. Or perhaps you have ideas for projects, but your current boards are being used already—for the cost of a few cups of coffee you can add another one to your toolbox.
