The main differences between the two versions are in the performance of the hardware used.
the version for the APM tab is expected to work with a cpu ATMEGA1280
to 16 MHz and supports both GPS, magnetometer, barometer and IMU.
In version Multiboard (the micro is AVR644P or 1283P ) are two boards connected together via a serial bus / SPI and a software library PRC.
first Board called Multipilot handles the Multicopter Stability , the
second Board called Multisensor handles the interconnection of sensors and
filter GPS, Magnetometer, barometer, sonar, IR sensor (obstacle
avoidance) and telemetry.
hardware solution proposed in this way is scalable and provides
programmers' double the computing resources compared to the first
approach 16 MIPS versus 40 MIPS.
the version of Arducopter Multipilot are supported brushless controllers i2c , the mixertable up to 12 engines for building configurations Quad,
Hexa, Okto, Deka and Dodeka cotter.HG3
is also supported in the the project, the first variable pitch opensource multicopter and Fox Hybrid, a Multicopter that can flight
as a biplane.
project coordination will be through the DEV international Conference
to be held on average once a week, the repositories will be supported
