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 data flows such as the ones to acquire data from the vehicle through the built-in support for the SAE J1939 and J1708 standards,” says Eurotech.

The DynaGate 20-30 carries certifications for E-Mark and SAE J1455, and offers EN62368 and UL60950 safety certifications, among others. The IP54 protected system supports -40 to 85°C operation. The aluminum-clad, 1.6 kg computer measures 224 x 150 x 62mm and offers optional conformal coating among other hardware and software customization services.

Two major SKUs are available, both with quad-core Apollo Lake SoCs. The model with a 1.6GHz/1.8GHz Atom x5-E3940 ships with 4GB of 1600MHz DDR3L and 16GB eMMC. The 1.6GHz/2GHz Atom x7-E3950 SKU has 8GB RAM and 64GB eMMC. Both integrate a microSD slot with a factory optional M.2 slot with a 128GB SATA III SSD.

The DynaGate 20-30 is equipped with 2x GbE ports with M12 X-coded connectors. There are also single USB 3.0 and 2.0 ports with noise and surge protection. A second USB 2.0 port hides under the service panel where you’ll also find a TTL Console port, audio in and out jacks, and reset and user buttons.

Isolated interfaces include RS-485, RS-232/RS-485/RS-422, 3x DI, 3x DO, and 2x CANBus, which supply 5V/100mA outputs. You also get a mini-DisplayPort, 2x analog inputs, a watchdog, TPM 2.0, a temperature sensor, and a 6-axis accelerometer and gyro. An odometer input is available as a factory option.

Wireless features include 802.11ac, Bluetooth 5.0 BLE, and optional, global LTE Cat 4 with 2G/3G fallback. There’s also a location device with GPS/QZSS/GLONASS/BeiDou/Galileo and Untethered Dead Reckoning and a factory option for real-time kinematic (RTK) satellite positioning. Dual nano-SIM Push Push slots are under the service panel.

The wireless features appear to be delivered via 2x mini-PCIe and a single M.2 slot, the status of which are expressed via three of the 6x LEDs. Two external SMA cellular antennas are available along with 2x RP-SMA antennas for WiFi/BT and a single SMA for GPS. The product shot shows 7x antenna mounts overall — the two extra mounts may be linked to the
