The BS2 Homework board is a very handy development board for your Basic Stamp 2 experiments.
The Basic Stamp 2 is really the workhorse of hobbyist microcontrollers, and Parallax has these new "Homework" boards that use a surface-mount BS2 module on a 3" x 4" board that also features a 9V battery clip, serial port connector, 5V voltage regulator and a small breadboarding space!
It features a "running" LED that's connected to the BS2's EEPROM clock, which only lights up if the BS2 is running. Put the module to sleep, and the LED turns off, making this have a very long battery life, even from just a regular 9V battery. This board also adds goof-proofing in adding 220 ohm resistors in series with all the I/O lines, protecting the module from mis-wiring. Nifty, eh?
Usually only sold in 10-packs from Parallax, we think these are simply too cool to not offer as individual units.
