Meggy Jr RGB
is a handheld platform for developing your own pixel-scale video
games. Meggy Jr has an 8x8 LED matrix display, six comfy buttons, a noise making
device, and even 8
extra
LEDs for whatever you like. Meggy Jr can run on batteries
or external power. Meggy Jr is fast, programmable, open source and hackable.

(Also: 16 MHz Crystal oscillator, ISP programming
interface, AAA battery box, a place to put a power
jack, power selector jumper, extra holes to access
ADC inputs of microcontroller and more.)
Mounting holes:
While these are normally used for mounting
Meggy Jr in a set of cool handles, you can
actually attach Meggy Jr to almost anything.
(Robo-Meggy Jr, anyone?)
CPU
:
An ATmega168, which is a type
of AVR microcontroller.
(You can also use an ’88 or ‘328.)
8x8 RGB LED Matrix Display:
That’s 192 LEDs all together. The LED matrix is
socketed so that you can pull it out if necessary.
Lo-Fi speaker:
Bzzt! Bleep! Bloop!
Printed circuit board:
White with black printing.
Outline: 5.300” x 2.800”
(About 13.5 x 7.1 cm)
Buttons:
Six big, comfy 12 mm
pushbutton switches with
molded key caps.
USB-TTL interface
If you have a USB-TTL cable, you
can use this port to program or
communicate with Meggy Jr, much
like you would with an Arduino.
Auxiliary LEDs:
Eight
extra
LEDs-- not in the matrix-- that can be used
(for example) to indicate lives, score, ammo, or level.
LED driver chips & transistors:
These components manage the current needed to
drive all those LEDs. Hidden underneath the LED
matrix display.
Reset Button
:
Optional
but
included with
the kit. Push to reboot.
Meggy Jr is here to play.
