Included Atmel MCU @ 8MHz
The MCU includes a preprogramed Arduino compatible bootloader.
USB programming and charging
The MobileNode is programed via USB by default
Power buttonAcceleration and geomagnetic sensor
ADCs, GPIOs and SPI
Small circular shape (7cm)
The MobileNode PCB is designed to be as small as possible, following all the recomendations given by the parts manufacturers.
There are 4 holes for M1.2 or M1.4 screws. So it is possible to put the MobileNode inside a box or case.
The UART ports of the GPS and GSM/GPRS modules can be connected externally, in order to debug. If the 4 jumpers are removed, the UART ports can be attached to an external device.
MobileNode includes an electret microphone. You can hear all what is happening near to the MobileNode with a voice call.
The microSIM socket is small
Since the MobileNode PCB is exposed to touch with hand, there are several TVS diodes, which protects sensitive parts such as the modules.
The M66 is a very small quad-band GMS/GPRS module which is able to handle TCP/ UDP/ PPP/ FTP/ HTTP/ SMTP/ CMUX/ SSL protocols.
This module is connected direclty to the battery, thereby it can measure the percent of its charge.
The M66 also includes Bluetooth connectivity, specifically the SPP, OPP protocols.
The L86 has a multi-GNSS engine for GPS, GLONASS, and QZSS. The cold start is <15s.
On board antennas
There is no need of attach external antennas to MobileNode, all of them are included in the board itself.
External GPS antenna
It is possible to connect an external antenna to the GPS module, since some aplications have to use the MobileNode indoor.
Free cloud account
Every MobileNode comes with an attached tag, which contains two keys: public and private keys. You can push data to the cloud by using your private key and you can access such data by using the public key. The GPS coordinates are shown in a Google Map including the device orientation data given by the geomagnetic sensor.
Many code examplesThe main example sketch allows you to send data to your free cloud account.
