Linux powered automotive computer is loaded with wireless

Eurotech’s rugged “DynaGate 20-30” is an automotive-certified IoT edge gateway that runs Linux on an Apollo Lake SoC with LTE Cat 4, WiFi, BLE, GPS, 2x GbE, and isolated DIO, serial, and CAN.

A week after announcing a BoltGate 20-31 transportation computer aimed at rolling stock applications, Eurotech has unveiled an “automotive-certified Multi-service IoT Edge Gateway.” The fanless DynaGate 20-30 runs the same Yocto-derived Eurotech Everyware Linux distribution with Eclipse tooling and Azul Java support on the same Intel Apollo Lake platform used by the BoltGate 20-31.

Like the BoltGate 20-31 and other Eurotech computers such as its AM335x-powered DynaGate 10-12 and i.MX6 UL based DynaGate 10-06 automotive computers, the new DynaGate 20-30 supports Eurotech’s Everyware Software Framework (ESF), a cloud-connected, Java/OSGi based IoT middleware stack with remote management and fieldbus support. ESF’s web-based UI allows non-developers to visually compose “powerful

of the information about car aerodynamics seems to be centered around generating
downforce. While this may be needed for race cars, the average 3000+
pound car driving at speeds below 90 MPH does not need to be concerned
with downforce. If you are trying to improve the efficiency of your
vehicle, reducing the
coefficient of drag (Cd) should be the main
concern. 



Rationale 




In this day and age of expensive fuel and inefficient vehicles, it makes sense
both economically and ecologically to conserve as much fuel as possible. To
accomplish this, you could go out and buy another car with better
mileage, but there are other options. This article focuses on how to optimize your current vehicle. 


The example vehicle is a 1998 Nissan Maxima. This is a rather boxy
4 door sedan with quite a lot of ground
