Embedded Gold Ready-for-Use Industrial PCB Assembly

GC370 • Single Board Microcomputer • Marvell® ARMADA® 3700 SoC


As a member of their Embedded Gold™ ready-for-use industrial PCB assemblies, EKF presents the GC370 64-bit industrial single board microcomputer for universal control and networking applications, equipped with a low power Marvell® ARMADA® 3700 SoC (ARM® v8 Cortex™-A53). Networking is provided through an M.2 wireless module (WiFi 6, Bluetooth), and by cable (RJ45 GbE). External devices can be attached to the USB3 Type-A receptacle. As an option, an isolated UART interface is available, either RS-232 or RS-485. The GC370 SBC has a wide-range 9-57VDC power input, via either an M12-A circular connector or terminal block (option).

Customer programming is hardware supported by means of the USB Type-B receptacle and the MicroSD card slot, or remotely across the RJ45 Ethernet jack. Typical applications of the GC370 SBC are router, gateway, data conversion, device controller, edge and fog computing. The GC370 has an internal mezzanine interface (SerDes 2.5GbE, MDIO) which can be used for mounting an Ethernet switch PCB. This enables switch management and/or protocol stacks e.g AVB/TSN, by the ARMADA® CPU. Eligible switch boards are e.g. the GL100, GL200, GL220.
