描述
正廠 Arduino Pro Micro – 5V/16MHz 美國 SparkFun 原裝進口
Pro Micro與 Pro Mini相似,除了板載ATmega32U4外。32U4內部的USB收發器使我們能夠在板上添加USB連接,並消除笨重的外部USB接口。
這個微小的電路板可以完成熟悉的所有Arduino技巧:9個10位ADC通道,5個PWM引腳,12個DIO以及硬件串行連接Rx和Tx。在16MHz和5V下運行,這個主板會提醒你很多你最喜歡的Arduino兼容主板,但是這個小傢伙可以在任何地方。有一個電壓調節器,所以它可以接受高達12VDC的電壓。如果您向電路板提供未經調節的電源,請確保連接到VCC上的“RAW”引腳。
這個最新的版本修正了最新版本的電路板上的絲線錯誤,因此引腳14被正確標記。我們還為電源電路增加了一個PTC保險絲和二極管保護,並對RX和TX LED電路進行了校正。

Pro Micro – 5V/16MHz
Here at SparkFun, we refuse to leave ‘good enough’ alone. That’s why we’re adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface. This tiny little board does all of the neat-o Arduino tricks that you’re familiar with: 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC. This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. We’ve also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit. Not sure which Arduino or Arduino-compatible board is right for you?
