$29 Inovato Quadra Arm mini PC runs Armbian on Allwinner H6 processor

Inovato Quadra is an Arm Linux mini PC based on Allwinner H6 quad-core Cortex-A53 processor with 2GB RAM, 16GB flash, and running Armbian-built Debian 11 Bullseye 64-bit. If the device looks like a repurposed Android TV box, it is because it is based on the T95 Mini model with one HDMI 2.0 port, USB 3.0 and 2.0 ports, a microSD card slot, a Fast Ethernet port and WiFi 4 wireless connectivity. Inovato Quadra specifications: SoC – Allwinner H6 quad-core Arm Cortex-A53 processor @ up to 1.7 GHz with Arm Mali-720 MP2 GPU System Memory – 2GB RAM Storage – 16GB eMMC flash, MicroSD card slot Video & Audio Output HDMI 2.0 port up to 4Kp60 3.5mm AV port with video composite and analog audio Networking 10/100M Ethernet port Wireless Quadra – 2.4 GHz 802.11n Wi-Fi 4, no Bluetooth (can be added with a USB dongle) Quadra Plus – Dual-band 802.11ac […]

Making a DIY 10.1-inch All-in-One PC out of AMR5 Ryzen 5 gaming mini PC

Hey Karl here. The first thing I need to do is thank the manufacturer of the brand Ace Magician for sending over a unit of their AMR5 gaming mini PC to more or less play with. I did a tiny bit of benchmarking along the way. This is the last time you will see the system in this state 😀 Story time. I have been really wanting a Steam Deck. But we purchased a Nintendo Switch about a year ago and it has barely been used. As soon as my son picked it up he asked why it was so laggy and has shown very little interest in it. So that got me worried about purchasing essentially a one-trick device. There have been a couple of good attempts at a DIY Steam Deck and I wanted to experiment with a small form factor. I went into this with a general […]

Getting Started with LoRaWAN on SenseCAP K1100 sensor prototype kit (Part 1)

CNXSoft: This getting started guide/review of the SenseCAP K1100 sensor prototype kit is a translation of the original post on CNX Software Thai. The first part of this tutorial describes the kit and shows how to program it with Arduino to get sensor data to a LoRAWAN gateway and display it on Wio Terminal, before processing the data in a private LoRaWAN network using open-source tools such as Grafana. The second part – to be published later – will demonstrate the AI capability of the kit. In the digital era where IoT and big data are more prevalent, a large amount of data is required to be collected through sensors. To enable the digital transformation, SeeedStudio’s SenseCAP K1100 comes with all necessary sensors and equipment including the Wio Terminal, AI Vision Sensor, and a LoRaWAN module. With this plug-and-play platform, makers can easily create DIY sensors for data collection and […]

Another consequence of supply shortage: mass production mishaps

Chips may suddenly disappear from the supply chain or get really expensive due to the recurring supply shortage, companies are now designing their PCBs to support multiple chips either selecting drop-in replacements or creating multiple footprints to cater to at least one alternative part. That means one PCB and multiple bill-of-materials are needed to be more resilient to any supply disruption. Radxa did that on the ROCK 3A board for the USB PD circuitry with the ability to use either Injoinic IP2315 or WCH CH224D IC. Those are not pin-to-pin compatible chips, and two circuitry were made for the board requiring two BoMs as it’s not just possible to only replace IP2315 by CH224D. But this information did not get to the inventory manager, and once IP2315 was out of stock, he/she believed it would be possible to simply replace IP2315 with CH224D. The unlucky part is that the factory […]

RAKwireless introduces WisBlock modular power supply, IP65 enclosures, and more sensor modules

RAKwireless Wisblock modular IoT prototyping system will get new modules about once every quarter and the latest Wisblock Summer 2022 event brings some RAK190xx base boards and power modules to support various power sources from solar panels to PoE, two IP65-rated “Unify” enclosures, as well as four new Wisblock sensor modules. Wisblock RAK190XX base boards and power modules The company has launched three base boards designed to take one of the five Wisblock power modules: RAK19009 – A small (47×30 mm) base board with only 2 sensor slots. RAK19010  – The “standard” base board with 4 sensor slots and 1 I/O slot RAK19011 – Version of the Dual IO base board with a power slot RAK19012 – WisBlock power module with USB, battery, and solar panel supply RAK19013 – WisBlock power module for rechargeable batteries and solar panel supply without the USB, for applications where you do not want to […]

Rock 5B RK3588 SBC preview – What works, what doesn’t in Debian 11

I’ve recently received an early sample of Radxa ROCK5 Model B (aka ROCK 5B) SBC part of the “Developer Edition” batch with 16GB RAM, and already showed the hardware and it booting successfully in Debian 11.

I’ve now spent more time with the board, and as part of the “debug party” tested performance and features in Debian 11. As one would expect, some things work fine, providing excellent performance, but others still need improvements.

Mekotronics R58 review – Part 2: Android 12 on Rockchip RK3588 CPU

I’ve written the first part of Mekotronics R58 review last month with an unboxing, teardown, and first boot with 3D graphics benchmarks. I’ve now had more time to play with Android 12 on the Rockchp RK3588 mini PC, so I’ll report my experience with the device. User interface and settings As already mentioned, the box ships with Android 12 for TV and the stock launcher. The Google Play store is working, and I had no troubles installing all apps I needed for the review. Most of the settings are pretty much standard. While the first time, I used Ethernet, and also tried WiFi 6 connecting the R58 to Xiaomi Mi AX6000 router. It worked but not without some effort, as initially, all I got were messages like “Couldn’t find SSID” both with 2.4GHz and 5GHz SSIDs. It turned out I had to disconnect the Ethernet to make WiFi work, and […]
