$50 ODROID-C4 Raspberry Pi 4 Competitor Combines Amlogic S905X3 SoC with 4GB RAM

Hardkernel has just launched an update to its ODROID-C2 board, with ODROID-C4 SBC equipped with a 2.0 GHz Amlogic S905X3 quad-core Cortex-A55 processor combined with up to 4GB RAM, four USB 3.0 ports, Gigabit Ethernet, HDMI 2.0 video output, and the usual 40-pin I/O header. That makes it a worthy competitor to Raspberry Pi 4 with 4GB RAM, especially since it supports Ubuntu 20.04, CoreELEC, Android 9, and LineageOS operating systems, and comes with a proper heatsink for cooling for just $50 plus shipping. ODROID-C4 specifications: SoC – Amlogic S905X3 quad-core Cortex-A55 processor @ 2.0GHz with Arm Mali-G31MP2 GPU supporting OpenGL ES 3.2, Vulkan 1.0 and OpenCL 2.0 System Memory – 4GB DDR4 Storage 1x eMMC connector (8/16/32/64GB modules available) 1x Micro SD slot with support for DS/HS mode up to UHS-I SDR104 Video & Output – HDMI 2.0 port up to 4K@60Hz with HDR, CEC, EDID Audio – Digital […]

Getting Started with Qoitech Otii Developer Tool using ESP8266 and Raspberry Pi 4 Boards

Last month, I received Qoitech Otii Arc power supply, power meter, and DAQ unit that aims at helping hardware and software engineers develop energy-efficient products. I’ve now had time to test the unit with an ESP8266 board and Raspberry Pi 4 SBC, so I’ll show how to get started and my overall experience with the hardware and program. Requirements and Initial Setup The unit takes a 9V power supply or micro USB adapter as power input, but power output is done through banana plugs. I did not have any cables with banana plugs so I bought one on eBay for about $5 shipped. This cable is really convenient with output to USB (female connector), crocodile clips, and hook clips. However, as we’ll see below it may not be suitable for all types of loads, and you may have to make your own with a higher rated cable. You’ll need to […]

YARC Case Can House a Raspberry Pi Board with one HAT Expansion Board and Up to 3 Hard Drives (Crowdfunding)

There are plenty of enclosures for Raspberry Pi board and other compact x86 or Arm Linux SBCs, but many projects require expansion boards and it’s not always possible to use an off-the-shelf case. That’s with that in mind that Stefano Zorzi and other enthusiasts have created YARC (Yes, Another Raspberry Case), a hexagonal case that supports the most popular single board computers, even when an add-on board – such as a Raspberry Pi HAT – is attached to the board. There’s enough space for up to three 2.5″ hard drives. Those are the boards officially supported (tested?) with the case: Raspberry Pi B +, 2B, 3B, 3B +, 4B, A +, 3A + Hardkernel ODROID C1, C2 AAEON Up Board Asus Tinker board and Tinker board S Radxa Rock Pi 4 Orange Pi PC, Pi PC2, Pi PC Plus Basically any board with compatible mounting holes can be installed in […]

Raspberry Pi powered Ventilators and 80+ Open Source Ventilators Listed & Ranked

With the (potential) shortage of ventilators due to COVID-19 pandemic, people have been working together to create cheaper and/or open-source ventilators, and we previously covered a smartphone-powered ventilator, as well as an open-source Arduino ventilator. It should come as no surprise some companies have started to make ventilators powered by Raspberry Pi boards. Raspberry Pi Zero Production Ramped up for Ventilators Tom’s Hardware reports the Raspberry Pi Foundation is specifically ramping up production of the $5 Raspberry Pi Zero because manufacturers are indeed integrating the tiny SBC into ventilators. Eben Upton, CEO and Founder of Raspberry Pi Foundation/Trading, explains: One of the main challenges with rapidly scaling manufacture of products like this is that you may be able to surge production of the air-handling elements, but you still need to provide the control element: often the components you need are on 20-week lead times and (hopefully) we’ll be out of […]

Know the Differences between Raspberry Pi, Arduino, and ESP8266/ESP32

CNXSoft: This is a guest post written in collaboration with SurfShark. When it comes to choosing a platform for STEM education or hobbyist projects, there are a number of low-cost, compact maker boards on the market. The most popular include the kid-friendly Raspberry Pi SBC that was designed with children in mind, Arduino boards for electronics projects, and more recently boards and modules based on EspressifESP8266 and ESP32 wireless SoC’s. In this post, we’ll look at the use cases and strong points for each of the boards whether you are just dabbling in the hobby of coding and DIY electronics, or you have a commercial project. Raspberry Pi The Raspberry Pi is a lineup of single-board computers (SBCs) that are from the UK and were first introduced in February 2012. These small computers were initially designed to teach students the basics of computer science, but they’ve found their way into […]

DFI GHF51 Ryzen Embedded R1000 SBC is about the Size of a Raspberry Pi

We’ve seen a fair amount of AMD Ryzen Embedded boards over the last few months including 3.5″ Ryzen Embedded SBC‘s such as Kontron SBC-VR1000 and IBASE Technology IB918, as well as larger boards such as SAPPHIRE FS-FP5R 5×5 motherboard. The most compact Ryzen Embedded board we covered so far must have been the upcoming Sapphire NP-FP5 based on Ryzen R1305G processor with a 4″x4″ (10.16 x 10.16 cm) form factor. But DFI GHF51 1.8″ SBC takes the crown of the smallest Ryzen Embedded SBC, with the business card / Raspberry Pi sized board measuring just 84 x 55 mm, and featuring an AMD Ryzen Embedded R1000-series processor combined with up to 8GB RAM. DFI GHF51 specifications: SoC – AMD Ryzen Embedded R1000 Series with Radeon Vega 3 GPU; 12W CPU System Memory – 2GB/4GB/8GB single-channel DDR4 3200MHz Storage 1x 16GB/32GB/64GB eMMC flash 64Mbit SPI Flash for BIOS (supports UEFI boot […]

Electrolama to Launch 802.15.4/Zigbee USB Dongle and Raspberry Pi “HAT”

Electrolama (@omerk and friends) has been working on two open-source hardware 802.15.4/Zigbee projects with “zig-a-zig-ah” (aka “zzh”) USB stick based on Texas Instruments CC2652R SimpleLink multi-standard wireless MCU and Zoe (Zigbee + Poe) development board based on Raspberry Pi HAT form factor and powered by TI CC2530 SimpleLink 2.4 GHz SoC alongside CC2592 range extender. Both boards are released under an Apache-based Solderpad Hardware License 2.0, and target users of the Zigbee2MQTT project.  The boards could soon also get native support in Home Assistant via the “zigpy-cc” library which adds support in ZHA (Zigbee Home Automation) integration component. Zig-a-zig-ah USB Stick Preliminary specifications: WiSoC – Texas Instruments CC2652R SimpleLink multi-standard wireless MCU with support for Thread, Zigbee, Bluetooth 5 Low Energy, IEEE 802.15.4g, 6LoWPAN, and proprietary systems. (Note: CC2652RB is also considered as it does not require an external crystal oscillator) Host Interface – USB via CH340 USB-UART bridge Misc […]
