Microprocessor
The “heart” of MGBox is an Atmel ATmega644P microprocessor that interfaces with the Sensor
over the I
2
C protocol. It features 64KB of flash memory, 2KB of EEPROM, 4Kbytes of internal
SRAM and general-purpose I/O lines.
In order to reduce circuit complexity and part count, the ATmega644P is configured to use its
internal oscillator running at 8MHz.
GPS Module
MGBox 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.
