Microprocessor

The "heart" of MGPBox is an Atmel ATmega2560V microprocessor that interfaces with the
2
Sensor over the I
C protocol. It features 256KB of flash memory, 4KB of EEPROM, 8Kbytes of
internal SRAM and 86 general-purpose I/O lines.
The ATmega2560 runs at 8Mhz using and external ceramic resonator.

GPS Module

MGPBox uses a GlobalTop PA6C GPS Module. The Module utilizes the MT3339 Chipset from
MediaTek. It features high sensitivity (-165dBm) and low power consumption. The patch
antenna is built in and the module can track up to 22 satellites.
The quick Time-to-First Fix of this module makes the use of a backup battery unnecessary,
which in turn removes the hassle of replacing batteries and at the same time not causing
additional pollution.
