Title: stand alone arduino chip?
Post by: blackbeard on August 11, 2009, 06:47:02 AM

i was wondering if it was possible to remove the microcontroler from an arduino and stick it on a standalone board made specificity for a robot i'm making i want it to be as low as possible and i'd like to avoid permanently sticking my arduino board onto it. i imagine all i would really need to do is add a resonator. what would be the circuit for that?

It is just the AVR and a 16mhz crystal as you said. Checkout the Arduino schematics and see how the crystal is hooked up.

oh ok perfect! just one other thing though. i seem to recall that the chip is flashed with a special firmwear or something meaning i can't just go on digikey and order the same chip. is this true or did i miss something somewhere?

You can order the same chip (atmega168 or atmega328), but you will need an ISP programmer such as the AVR ISP MKII to flash the programs (and then you don't need the USB bootloader)

you can also buy the arduino chips pre-flashed with the boot loader from various sites

http://www.moderndevice.com/ offers 2 different versions of the chip with the bootloader programmed onto them
