New XBee Board, MIDI Interface, 32ch LED Driver

I recently introduced three new Arduino compatible boards and peripherals --
an '328+XBee board, MIDI interface and 32ch LED driver. The details are below.

Low-cost ($20) ATmega328 design with
RTC (DS1337) and XBee

NB1A-LED (­)
32 channel LED driver for the NB1A, NB1
and ZB1 based on the TLC5940. Works
with the Arduino Tlc5490 library.

* LEDs are powered by a separate adjustable
linear regulator. Power dissipation in
the '5940's can be minimized by adjusting
the anode voltage just above the LED

* Number of channels can be increased
by using multiple cards and the
NB1A backplane

* Current per channel can be increased
by paralleling cards.

* Can be used with low-cost IDE cables.
See Knight-Rider demo at­

MIDI interface + four LP filters for the
NB1A, NB1 and ZB1. Works with the MIDI 3.0
library for the Arduino. MIDI input is
disabled during bootup

I live in Somerville too ... MIDI board looks very clean.!

I'll be using the MIDI library pretty soon, will keep your board in mind!
