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.

在這裡,在SparkFun,我們拒絕離開'足夠好'孤單。這就是為什麼我們要添加到的Arduino兼容微控制器一旦我們更多的陣容!臨微型類似於臨迷你除了在船上的ATmega32U4。在32U4內的USB收發器可以讓我們板載添加USB連接和廢除體積較大的外部USB接口。
這個小小的板做所有你熟悉的整齊鄰Arduino的招數:4通道10位ADC,5 PWM引腳,12的DIO以及硬件串行連接Rx和Tx。運行頻率為16MHz和5V,這個委員會將提醒你很多您喜愛的其他的Arduino兼容的電路板,但這個小傢伙可以去任何地方。機上有一個電壓調節器,因此它可以接受電壓高達12VDC。如果你提供不受管制的電源板,一定要連接到“RAW”引腳VCC沒有。
這個最新版本修正從董事會的最後一個版本,絲綢錯誤,使銷14正確標記。我們還增加了一個PTC保險絲和保護二極管電源電路和糾正RX和TX LED電路。
