Raspberry Pi CM4 boards offer dual Ethernet, 4G LTE

Raspberry Pi CM4 Dual Ethernet

Since the launch of Raspberry Pi CM4 and CM4Lite systems-on-module last October, we’ve seen carrier boards bring their own set of features including industrial communication interfaces, a stereoscopic camera, four SATA ports to build a NAS, a DIN-rail based industrial controller, and more. But so far, I have not seen a Raspberry Pi CM4 carrier board with dual Ethernet ports. Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” was brought to our attention this morning, but there’s another one with 4G LTE connectivity, Fast+Gigabit Ethernet ports, and extra I/Os courtesy of MCUZone’s CM4-4G IO board. Let’s have a look at both of them. Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4 Specifications: Supported SoMs – Raspberry Pi CM4 and CM4Lite with up to 8GB RAM, 32GB eMMC flash, optional WiFi & Bluetooth Storage – MicroSD card slot to load OS on CM4Lite […]

Mcuzone MDK3308-EK Rockchip-RK3308 Development Board

Rockchip RK3308 is a quad-core Cortex-A35 processor that was announced in 2018 together with RK3326  specifically for Smart AI solutions. While the processor is equipped with an RGB LCD output interface, it does not come with a 2D or 3D graphics accelerator, so it’s better suited to smart speakers with an optional display using a basic user interface. I’ve not seen many hardware platforms or boards based on the processor, but today I noticed “Hangzhou Wild Chip Tech” had an RK3308 system-on-module, as well as development kits for sale on Aliexpress with the module price starting at $23. Mcuzone MDK3308 Coreboard Specifications: SoC – Rockchip RK3308 quad-core Cortex-A35 processor @ 1.3 GHz with NEON and VFPv4 FPU System memory / storage configurations: 256MB DDR3/3L + 256MB NAND flash 512MB DDR3/3L + 8GB eMMC flash 2x 100-pin dual row headers (1.27mm pitch) exposing: Display – LCD interface up to 1024×600 (RGB), […]
