Arduino that runs an 8 MHz bootloader on a super small, super thin board.

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!

8-channel 16-bit simultaneous-sampling USB-C data acquisition board using ESP32-S3-WROOM-1U-N8 and ADS8588S, with ±10 V single-ended analog inputs and separate filtered analog 5 V supply.
