6. Rx and Tx Hardware Serial Connections
1.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.
2.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.
3.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.
