So, you want to build your own Arduino? Learn how! This kit is perfect for someone who wants a simple, barebones Arduino compatible device. It can be built on a breadboard for demonstration purposes, then soldered to the included board. The included AVR is pre-programmed with an Arduino bootloader. Simply solder the included parts together, apply power, and the LED begins to blink indicating proper operation. Kit contains: 1 - ATMEGA328P-PU microcontroller 1 - PCB 2 - 14 pin male header 1 - 6 pin ISP header 1 - LED 1 - 16Mhz crystal 1 - 10k Ohm resistor 1 - 330 or 470 Ohm resistor (for LED current limiting) 3 - 22pF capacitors 1 - schematic Note: After it is built, this device requires either an ISP programmer to upload custom code, or another arduino-compatible device to program it (see http://arduino.cc/en/Tutorial/ArduinoISP). We recommend investing in a cheap 'USBASP' device to be used for all of your AVRs. |
