DFRobot (DFR0010) DFRduino Nano Board, Atmega328-20AU, 8 bit, AVR

DFR0010 is a DFRduino Nano (Arduino Nano Compatible) board. The DFRduino NanoUSB microcontroller V3.1 (ATMega 328) is a breadboard-ready version of the "Arduino mini" with integrated USB. The "Arduino Nano" has everything that theDiecimila has (electronically), with more analogue input pins and an on-board+5V AREF jumper. The "Arduino Nano" automatically senses and switches to thehigher power supply, so there is no need for a power select jumper. The Nano'spin layout works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on onetop, power and ground on the other). The DFRobot DFRduino Nano USBmicrocontroller V3.1 (ATMega 328) can be powered via the mini-B USB connection,6-20V unregulated external power supply, or a 5V regulated external powersupply. The power source is automatically selected as the highest voltagesource.- Automatic reset during program download- Power OK blue LED on the bottom and Green (TX), red (RX), and orange (L) LED- 32 KB (of which 2KB is used by the bootloader) flash memory- 2KB SRAM, 1KB EEPROM, and 16MHz clock speed- Auto-sensing/switching power input- Small mini-B USB for programming and serial monitor (cable not included)- ICSP header for direct program downloads- Power OK blue LED on the bottom- Standard 0.1" spacing DIP (breadboard friendly)- Manual reset switch
