A tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost arduino-IDE programmable board!

Compact surface-mount production variant of the fixed-function, crystal-referenced low-power burst timer. Electrically equivalent to the through-hole version where practical, with selectable interval, duration, carrier frequency, AUTO/TEST mode, ENABLE output, and gated OSC_OUT; no MCU, firmware, PLL, VCO, or programmable logic.
