Leonardo pro Micro pro mini USB控制板 开发板

特点：

使用进口ATMEGA32U4 AU原装芯片

尺寸：23mm*40mm

• ATMEGA32U4在5V/16MHz运行

• 支持下的 IDE V1.0.1

• 开发板微型USB接口编程

• 4个10位ADC引脚

• 12个数字I / O（5 PWM能力）

• Rx和Tx硬件串行连接

说明：

这个小小的板做所有的整齐邻的技巧：4通道10位ADC，5个PWM引脚，12的DIO以及硬件串行连接Rx和Tx你熟悉。运行在16MHz和5V，这个委员会将提醒你很多其它您喜欢的兼容的电路板，但这个小家伙可以去任何地方。在船上有一个电压调节器，所以它可以接受电压高达12VDC。如果你是供应不稳定的电源板，一定要连接到的“RAW”不VCC引脚。这个最新版本修正丝绸错误，使引脚14是正确的标记。我们还增加了一个的PTC保险丝和二极管保护电源电路和纠正RX和TX LED电路

Pro Micro - 5V/16MHz
DEV-11098RoHS CompliantOpen Source Hardware

Description:Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of 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 tricks that you're familiar with: 4 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 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.
