INTRODUCTION:
MOD-PULSE is an instrument for monitoring the blood oxygenation of a
human. By measuring the oxygen level and heart rate, MOD-PULSE can display the
levels of blood oxygenation and heart rate on it's LCD display. To perform it's func-
tionality, MOD-PULSE requires external sensor connected to it via PROBE connect-
or. MOD-PULSE can be connected to variety of OLIMEX's development boards via
it's UEXT connector.

ELECTROSTATIC WARNING:
The
MOD-PULSE
board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS:
Cables:
The cable you will need depends on the programmer/debugger
you use. If you use MSP430-JTAG-TINY, MSP430-JTAG-TINY-V2, or MSP430-
JTAG-ISO, you will need USB A-B cable. If you use MSP430-JTAG, you will need
LPT cable.
