SparkFun Pro Micro - 5V/16MHz Boards, Sparkfun OriginalsHere at SparkFun, we refuse to leave good enough alone. Thats why were 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 youre familiar with: 4 channels of 10 bit

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: 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 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 stiff or tight…
Size: 13.5 Little Kid, Color: Turquoise/Multi
My niece loved them. So many of the slips in shoes are too stiff and tight, this one was easy on, not stiff or tight, just perfect!

Narrow
Size: 11.5 Little Kid, Color: Lavender
These were so cute, but run narrow. My daughter tried wearing them but she kept complaining they were too tight. Wish we could love them because I love how easy this brand is for my daughter to get on her feet
