$55 ODROID-GO Advance Linux based Retro Game Console is Powered by Rockchip RK3326 Processor

Last year, Hardkernel took some time away from Arm and x86 Linux SBCs with the launch of ODROID-GO retro game console powered by Espressif Systems ESP32 processor. The console could be programmed with the Arduino IDE, and the $32 price tag made it a popular item despite the limited processing power fo the ESP32 dual-core processor. The good news is that the console got an upgrade with ODROID-Go Advance equipped with a Rockchip RK3326 quad-core Cortex-A35 processor coupled with 1GB RAM to run Linux, and featuring an upgraded 3.5″ wide-viewing angle color display. ODROID-GO Advance specifications: SoC – Rockchip RK3326 quad-core Arm Cortex-A35 processor @ 1.3GHz with Mali-G31 MP2 GPU System Memory – 1GB DDR3L @ 786Mhz, 32 Bits bus width Storage – 16MB SPI Flash for bootloader, Micro SD Card slot (UHS-1 Capable interface) Display – 3.5″ 320×480 TFT LCD (Wide-viewing angle display, MIPI-DSI interface) Audio – 3.5mm earphone […]

This Business Card is a $3 Linux Computer Powered by Allwinner F1C100s SoC

The smallest, thinnest Linux computer There are many business card-sized SBCs, like RPi 4. But George Hillard, an embedded systems engineer decided it would be interesting to build an actual business card that was a computer. His card runs Linux and houses an Allwinner F1C100s carrying an ARM9 processor with 32MB RAM and 8MB flash storage. The Basics It holds some of his photos, a copy of his resume and a couple of games, which is pretty good for something like a business card. There is a USB port off one corner, and the unit can connect to a computer and boot up in about 6 seconds and shows up under USB as a flash drive. But that piggybacked computer-attached display is really the only type of display the card can manage. The Shell and Linux Version The shell has the games, including a version of 2048, and a small […]

Some Interesting Talks from FOSDEM 2020 Schedule

We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]

Banana Pi BPI-F2S Industrial SBC Launched for $58 with Linux 4.19 based Debian or Fedora OS

Last month we covered Banana Pi BPI-F2S single board computer (SBC) for industrial, IoT, and smart audio application that was powered by the intriguing SunPlus SP7021 “Plus1” processor featuring four Cortex-A7 cores, one ARM9 ARM9 real-time core, and one 8051 I/O controller core, as well as up to 512MB built-in DDR3 RAM. At the time, the board was not available, and we had limited information about software support, except the company would provide a Yocto-based Linux distribution. The good news is that you can now buy Banana Pi BPI-F2S industrial SBC on Aliexpress for $58 and Taobao for 390 RMB, and the company released source code and OS images for the board. Here’s a reminder of Banana Pi BPI-F2S specifications: SoC – Sunplus SP7021 “Plus1” with a quad-core Cortex-A7 processor @ 1.0 GHz, one Arm A926 microprocessor, an 8051 core to handle I/Os, and 128MB or 512MB DDR3 DRAM. Storage […]

Beelink T45 Review with Windows and Linux, and Tweaking BIOS Power Limits

[Update December 23, 2019: We’ve been informed by Beelink that the T45 has been updated to the 6W Celeron N4200 processor instead, and the system is now cooled with a fan. The model reviewed in this post is the fanless version with a 10W Intel J4250 processor, which was never sold] [Update January 30, 2020: We’ve now posted a review of the new model at Beelink Gemini T45 Pentium N4200 Mini PC Review] Beelink have further extended their ‘Gemini’ range of mini PCs by adding the T45. This is a passively cooled mini PC that is effectively a companion to the J45 as it again uses the slightly older Apollo Lake Intel Pentium J4205 CPU which is a quad-core 4-thread 1.50 GHz processor boosting to 2.60 GHz with Intel’s HD Graphics 505. Although the T45 is a ‘NUC’ style mini PC physically consisting of a 119 x 119 x 17.7 […]

RAK7244 LoRaWAN Developer Gateway Combines Raspberry Pi 4 with LoRa HAT, Optional 4G LTE Connectivity

After launching RAK831 Lite LoRaWAN gateway based on Raspberry Pi 3 board in 2018, RAK Wireless introduced Pilot Gateway Pro RAK7243 gateway with the more recent Raspberry Pi 3B+ SBC earlier this year. But with the launch of Raspberry Pi 4 last June, the Raspberry Pi 3B+ has become much harder to procure, so RAK has now launched an updated LoRa gateway featuring Raspberry Pi 4 SBC together with the company’s RAK2245 Pi Hat Edition LoRaWAN gateway concentrator module. RAK7244 LoRaWAN Developer Gateway specifications: SBC – Raspberry Pi 4 Model B with 2GB RAM Connectivity LoRa RAK2245 Pi Hat LoRaWAN gateway concentrator module with 1x SX1301 baseband processor, 2x SX125x Tx/Rx front-ends LoRaWAN v1.0.2 support Support for 8 channels and spreading factors SF7 to SF12 Bands – 433MHz, 470MHz, 865MHz, 868MHz, 915MHz, 920MHz, 923MHz Tx Power: 27 dBm Max RX Sensitivity: -139dBm Cellular – Optional 4G LTE support via RAK2013 […]

OpenWiFi Open-Source Linux-compatible WiFi Stack Runs on FPGA Hardware

WiFi is omnipresent on most connected hardware, and when it works it’s great, but when there are issues oftentimes they can not be solved because the firmware is a closed-source binary. I understand companies do that either to protect their IP and/or make sure end-users do not break FCC compliance. OpenWiFi project aims to deliver a completely open-source SDR (Software Defined Radio) WiFi implementation compatible with Linux and running on FPGA hardware. OpenWiFi currently supported features: 802.11a/g; 802.11n MCS 0~7; 20MHz Mode tested: Ad-hoc; Station; AP DCF (CSMA/CA) low MAC layer in FPGA Configurable channel access priority parameters: duration of RTS/CTS, CTS-to-self SIFS/DIFS/xIFS/slot-time/CW/etc Time slicing based on MAC address Easy to change bandwidth and frequency: 2MHz for 802.11ah in sub-GHz 10MHz for 802.11p/vehicle in 5.9GHz The developers tested OpenWiFi on Xilinx ZC706 FPGA evaluation kit coupled Analog Devices fmcomms2/fmcomms4 RF board to form an access point, and connected it to […]
