STK200 compatible 10 Pin programming port.
All I/O pins of micro are silkscreened labeled and brought out to .1" space headers for easy external connections.
Professional quality board with silkscreen.

Power requirements:
Requires external 8-12 volt DC supply.

The AVR8515FB was designed to take advantage of the many free AVR assemblers and compilers available on the web as well as any commercial versions.
We recommend and use Imagecraft ICCAVR C compiler.
There is also a "free for personal use" BASIC compiler available. RVK-Basic was featured in a series of "howto" articles in Nuts & Volts magazine.
WinAVR is the free windows Gnu GCC compiler. This a very good C compiler.
There is also SmallC for AVR available for free. We haven't tested this yet.
For info about other compilers available for the AVR, check out AVRfreaks.
Any STK200 compatible programming software can be used to program the AVR. The freely available PonyProg programmer works well.

Bare PC Board: $15.00 (order 10 or more at $11 each) (Click here for image)

No assembled units or parts kit are available. Bare PC boards are in stock.

Please include $5 shipping and handling for destinations within the continental United States. All other areas, please us for shipping charges.

For those only interested in purchasing a single bare pcb board, shipping and handling can be avoided by sending us the cost of the pcb and include a self addressed stamped envelope with your order. Please attach three first class stamps to the envelope with your legible return address. We suggest using cardboard floppy disks envelopes that can be purchased at office supply stores. US only.
