副廠 Arduino Pro Micro 採用 Atmega32U4 自身usb更新程序5V/16M 單片機開發板

Pro Micro – 5V/16MHz 是使用ATmega32U4控制器 5V / 16MHz，主要採取了低價位、周邊不焊接接腳，方便使用者自行連接不同種類pin腳。這個小巧的電路板完成了您熟悉的所有Arduino巧妙技巧：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。該板運行在16MHz和5V電壓下，將使您想起許多其他您最喜歡的Arduino兼容板，但是這個小傢伙幾乎可以在任何地方去。板上有一個穩壓器，因此可以接受高達12VDC的電壓。如果要為電路板供電，請確保連接到非VCC的“ RAW”引腳。

Pro Micro – 5V/16MHz

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.
