Raspberry Pi CM4 based 7-inch industrial Panel PC takes IO board with RS232, 12V-24V inputs and outputs

The ComfilePi CPi-C070WR4C is a 7-inch industrial Panel PC powered by a Raspberry Pi CM4 module with GPIO, RS-232, RS-485, and I2C interfaces as well as the ability to add two more RS232 interfaces and several 12V-24V DC inputs and outputs through an I/O board connected to the GPIO port of the panel PC. The new panel PC is an update to the ComfilePi Industrial Touch Panel PC introduced with a Raspberry Pi CM3 module in 2017. Besides upgrading to a more powerful Raspberry Pi Compute Module 4, COMFILE also makes use of an RS-485 port that utilizes a full UART interface that does not exhibit the limitations of the mini-UART interface, and also added the CP-IO13-4C I/O board for even more expansion capabilities. ComfilePi CPi-C070WR4C specifications: SoM – Raspberry Pi Compute Module 4 with SoC – Broadcom BCM2711 quad-core Arm Cortex-A72 processor @ 1.5GHz with VideoCore Vi GPU supporting […]

Green Metrics Tool helps developers measuring & optimizing software power consumption

The Green Metrics Tool (GMT) is an open-source framework that allows the measurement, comparison, and optimization of the energy consumption of software with the goal of empowering both software engineers and users to make educated decisions about libraries, code snippets, and software in order to save energy along with carbon emissions. While the firmware of battery-powered embedded devices and the OS running on your smartphone are typically optimized for low power consumption in order to extend the battery life, the same can not be said of most software running on SBCs, desktop computers, and servers. But there are still benefits of having power-optimized programs on this type of hardware including lower electricity bills, a lower carbon footprint, and potentially quieter devices since the cooling fan may not have to be turned on as often. The Green Metrics Tool aims to help in that regard. The developers explain how that works: […]

GL.iNet Beryl AX OpenWrt router review – WiFi 6 performance, repeater, NAS, and 4G hotspot modes

Power bank GL.iNet GL-MT3000 Beryl AX router

In the first part of the review of GL.iNet GL-MT3000 “Beryl AX” pocket-size WiFi 6 OpenWrt router we had a look at the specifications, the package content, and the hardware design with a teardown of the little router. I’ve now had more time to play with the router focusing the review on WiFi 6 performance, and some of its functions such as repeater, NAS, and 4G hotspot. The router also supports VPN client and server modes, the Tor network, and Adguard Home, but I’ll invite readers to check out the GL.iNet Brume 2 security gateway review since I went through all these, and the hardware is very similar minus wireless connectivity. Initial setup of the Beryl AX router If you connect an Ethernet cable to the router you can switch to step two. If you only rely on WiFi for the setup that works too as the Beryl AX router […]
