MAVRIC-II
BOARD
The
MAVRIC-II board we used includes an ATmega128 microcontroller.
All the I/O ports are brought out to standard pins.
It has power regulation, and RS-232 level shifters,
and it’s on a solder-masked PCB.
Soldering
the kit together required a lot of surface-mount
soldering. Sometimes we had to use a magnifying
glass. One kit was soldered with a low-temperature
Radio Shack soldering iron. The other was done in
our senior project lab with a Weller solder station.
We successfully assembled and tested both kits.
The
MAVRIC-II allowed us to go straight to breadboarding
while our sensor board PCB was created and sent
out for fabrication. We had pin-compatible DIP package
parts to breadboard the ADC and accelerometer. Next,
we set up serial communication and prototyped the
Visual Basic software. Using serial communication
allowed us to debug and test the code’s function
with HyperTerminal.
