Three extra digital I/O lines are accessible through the ISP header.
These values are rough approximations for comparison purposes. Available current depends on input voltage,
current consumed by the board, ambient conditions, and regulator topology. See product documentation and
performance graphs for details.
Without included optional headers.
1.1. Supported operating systems
The A-Star 32U4 boards can be programmed using any operating system that supports the Arduino environment. We
have tested the A-Stars, our Arduino software add-on, and the Arduino IDE on Microsoft Windows 8.1, 8, 7, Vista,
XP (with Service Pack 3), Linux, and Mac OS X.
