Overview Core CPU (called "A9") is Qualcomm based SDM 450 running Google AndroidTM platform that use to be embedded into several products to allow basic operation system. Based on the A9 module that combined with more peripherals system, can build full final range of products for any purpose in fleet management environment. A9 platform support the following features: WiFi, Blue tooth, Cellular capability, NFC, GPS, variant communications and variant sensors. Rev.

Operation 1. Connect power source to the A9 module (power supply or battery according the rating defined above). 2. Connect the peripherals items according the application. (Speakers, Antennas, Screen, etc.). 3. Burn the relevant operation system image (by USB device port) using Google "fast boot" tool via ADB interface. 4. Push the power key, after system loads, the basic AndroidTM screen will appear on the screen if connected to the module. (See fig 1 as sample basic screen).
Compliance Information FCC Compliance: FCC Compliance Statement: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. This device must accept any interference received, including interference that may cause undesired operation. Product that is a radio transmitter is labeled with FCC ID.
Antenna Installation A9 has 4 antenna port：PRX antenna、DRX antenna、GPS antenna、wifi&BT antenna，as below picture , all antenna ports have 50Ω impedance. 1.PRX antenna reference design A9 kept πkind circuit in board for antenna , it can adjust impedance automatically according to actual antenna tune status , so that it could get best output performance.
