SparkFun BlackBoard 開發版 相容 Arduino Uno R3 更勝一籌 支援 Qwiic 接頭 串聯更多感測器
來自 SparkFun BlackBoard 開發版 就是Arduino Uno中所需的一切,並帶來許多額外的特權。BlackBoard擁有您所熟悉和喜愛的所有硬件外設:14個帶6個PWM引腳的數字I / O引腳,4個模擬輸入,UART和SPI以及少量外部中斷引腳。BlackBoard甚至還有一個SMD ISP接頭,用於連接SPI引腳和屏蔽層。
我們已經應用了我們學到的有關製作更好Uno的每一課,並創建了黑板。USB轉串口現在用無處不在的CH340G完成,需要更少的驅動程序安裝和具有通孔錨定的堅固的microB連接器。我們對黑板的電源部分進行了重新設計:我們對3.3V穩壓器進行了升級,以提供高達600mA的電流,並提供全面的熱和反向電路保護,並增加了額外的去耦電容,以提高ADC讀數的靈敏度。我們已經將功率LED,引腳13 LED和TX / RX LED的亮度從盲化降至最佳。我們在電路板的邊緣添加了3.3V電壓轉換和Qwiic連接器,以便與我們不斷增長的基於I 2 C的Qwiic系列產品快速無縫連接 產品。
對於更高級的用戶,我們添加了I / O跳線。將跡線切割為5V並將跳線焊接至3.3V端,電路板將以3.3V運行。如果您需要屏蔽或3.3V敏感設備(如SPI接口)需要保護,這非常方便。
SparkFun BlackBoard 開發版 經過 ptiboot 引導程序的全面測試,可以使用Arduino中的’Arduino / Genuino Uno’選項輕鬆編程。您可以通過USB或通過桶形插孔給黑板供電。板載電源調節器可以處理7至15VDC的任何情況。請查看下面的相關項目以獲取兼容的壁式電源。

SparkFun BlackBoard
The BlackBoard from SparkFun is everything you need in an Arduino Uno with many extra perks. BlackBoard has all of the hardware peripherals you know and love: 14 Digital I/O pins with 6 PWM pins, 4 Analog Inputs, UART, and SPI with a handful of external interrupt pins. BlackBoard even has an SMD ISP header to connect SPI pins to shields.
SparkFun BlackBoard
We’ve applied every lesson we’ve learned about making a better Uno and created the BlackBoard. The USB to serial is now done with the ubiquitous CH340G requiring fewer driver installs and a rock solid microB connector with through hole anchoring. The power portion of the BlackBoard has been reworked: we upgraded the 3.3V regulator to provide up to 600mA, with full thermal and reverse circuit protection, and added extra decoupling capacitance to increase the sensitivity of the ADC readings. We’ve decreased the brightness of the power LED, pin 13 LED, and the TX/RX LEDs from blinding to just perfect. We’ve added 3.3V voltage translation and a Qwiic connector to the edge of the board to allow for quick and seamless connection to our ever-growing line of I2C based Qwiicproducts.
SparkFun BlackBoard
And for more advanced users we’ve added an I/O jumper. Cut the trace to 5V and solder a jumper to the 3.3V side and the board will run at 3.3V. This is extremely handy if you have a shield or 3.3V sensitive devices, such as an SPI interface, that needs protecting.
The SparkFun BlackBoard comes fully tested with the Optiboot bootloader and can be easily programmed with the ‘Arduino/Genuino Uno’ option from within Arduino. You can power the BlackBoard over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15VDC.
