At the heart of Scroll pHAT is ISSI's IS31FL3730 matrix LED driver chip. It can drive multiple LED matrix and segment display formats and also supports controllable display brightness.
Scroll pHAT has a matrix of 5x11 (55 total) bright white LEDs that is ideal for scrolling messages, showing graphs, and drawing pictures. Use it to output your IP address, show CPU usage, make a scrolling name badge, or play pong or snake!
