SparkFun Pro Micro - 3.3V/8MHz Chip Adapter

SparkFun Pro Micro - 3.3V/8MHz Chip AdapterHere 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

compact transducer that can excite a surface or structure over a wide bandwidth

and is Arduino IDE compatible

tactile sensations from your music and movie sound tracks

Two of these ICs allow you to split a stereo audio input into 7-bands (per channel) and read the amplitude of each using the ADC on your Arduino

The module is kept small and simple

and not as a first dev board

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at about 3

all of the power rails are brought out to a binding post

If you'd like to back up the RTC for faster fix-recovery

starting multiple tracks in sample-sync and smooth cross-fading between tracks

32x32 or 32x64 RGB LED Matrices with HUB75 connections

(It's not big enough to be an official HAT
