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 – -20°C to +75°C The gateway runs Linux and supports ModBus […]

If your WiFi router range does not cover some of your rooms what do you do? You install a WiFi repeater or some of the more recent WiFi mesh networking solutions. What I did not know is that you can do something similar for cellular connectivity if you don’t quite get a reliable signal from your telco’s base station. Specifically, I’ve just come across a 900 MHz GSM repeater & signal booster that claims to be able to extend the 2G, 3G, and 4G cellular signal in a 100 to 300 m2 area, and sold for $59 on Banggood. Here are the specifications listed for the GSM repeater: Operating Frequency Band – GSM Uplink: 890-915Mhz Downlink: 935-960Mhz Gain: 70dbm Outdoor Directional Antenna Gain – 8dB Compatible with 2G / 3G / 4G cell phone signal Power Supply – 12V DC via 110-240V DC adapter Dimensions – 135 x 105 x 23 mm (Aluminum Alloy) Temperature Range – -10 to 60°C […]
