How much do you pay for cellular data plans?

I’m mostly working from home using a broadband “Fiber-to-the-home” monthly subscription, with a router handling the connection to computers and devices through Ethernet or WiFi. So I’ve very seldom used cellular data plans since I don’t exactly need to be connected each time I get out. But recently, I’ve been to places for around one or two weeks at a time without WiFi, and my ISP has gotten into the habit of disconnecting for several hours once a month, so I’ve started to connect to 4G cellular networks more often. So far I had purchased daily or weekly plans from my bank app depending on my need for under two dollars a day or $10 per week for a 10 Mbps “unlimited” connection. Unlimited here means the company will not throttle the connection to lower speed after reaching a cap. I had some problems with excessive packet loss (> 70%) […]

Raspberry Pi CM4 boards offer dual Ethernet, 4G LTE

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 […]

SigmaStar SSD201/SSD202 powered 4G LTE industrial gateway made to run mainline Linux

SigmaStar SSD201 is a dual-core Cortex-A7 processor with 64MB RAM onchip that is designed for smart HD displays. We’ve previously seen it in Industio 7-inch smart display running Linux, but if you want to modify anything you’d need sign an NDA before getting the SDK. Luckily there’s an open-source community named linux-chenxing that aims to bring mainline support to those low-cost SigmaStar processor to mainline, the same way linux-sunxi is working on Allwinner processors. Daniel Palmer noticed MYZR recently launched GW300 4G LTE industrial gateway with specifications that looked familiar. GW300 specifications from manufacturer’s website: Processor – Arm Cortex-A7 dual-core processor @ 1.2GHz Memory – 64MB RAM Storage – 128MByte Flash Connectivity – Ethernet and 4G LTE with high-gain antenna Serial – RS485/ RS232 via 5-pin terminal block Misc – RTC Power Supply – 12V to 24V DC input Dimensions – 127.7 x 87.5 x 30 mm Temperature Range – […]
