What is it?

Instantly add ISP capability, reset and clock circuitry to your AVR/Attiny/8051/8052 circuit (see device list below). This board is perfect for use in a breadboard circuit. Each board includes an R/C reset circuit, a clock circuit, and an ISP circuit. Every MCU pin is brought out to a header pin row and easily plugs into your breadboard or existing circuit. You will receive 5 blank boards (no components included or installed). Free shipping is available if you are in North America.

Why did you make it?

Constantly changing configuration when prototyping circuits, I was looking for an easier way to just plug in an AVR/ATtiny/8051/8052 into my breadboard with all the necessary requirements to make the circuit run.

What makes it special?

ISP programming is made easy with a 10 pin ISP connector footprint on the board. When you are testing your code this is necessary so you do not have to unplug the chip every time to program it, risking breaking off the pins. Because every pin is brought out to a header strip, it is very easy to attach debugging devices, (oscilloscope, logic analyzer,etc.) Schematic diagram is available for download when purchasing this item.
