Evil Mad Scientist Laboratories has released Peggy 2LE:

Peggy 2LE (“little edition”) is a diminutive version of our popular Peggy 2 LED “pegboard” an open-source LED matrix display. Peggy 2 is big, designed to fit a 25×25 grid of 10 mm LEDs. Peggy 2LE is mostly the same, just smaller: it’s designed to fit 5 mm LEDs.

What’s New in Peggy 2LE?

Peggy 2LE supports the same basic functionality as the larger Peggy 2: it drives up to 625 LEDs of up to 5 mm size. Still open-source and hackable. Arduino compatible. Code-compatible with Peggy 2– every Peggy 2 program can run on the Peggy 2LE.

The four main differences between the two are:

   1. Peggy 2LE is smaller– about 1/4 the size.

   2. Peggy 2LE does not have a battery box. You can still use batteries if you want to (3xD cell) but a holder is no longer on board. Instead, it’s designed to run off of an ac power adapter.

   3. Peggy 2LE does not have the breadboard-style prototyping area on board. (Did we mention that it’s smaller?)

   4. Peggy 2LE can be built with a hardware serial port.
