March Update: Introducing the QuartzPro64
This month we’re announcing the QuartzPro64 - a new single-board computer based on Rockchip’s powerful RK3588 SoC. This is our first Pro-grade SBC since the introduction of the ROCKPRo64, and I believe it to be a worthy successor to the much revered Pro lineup.
Free Stuff - February 2022
The February recipient for the Great Scott Gadgets Free Stuff Program is Matthew Hilts! Matthew is a student at the University of Dayton who will be spending his Spring semester learning about and using GNU Radio. To help enhance his studies we have sent Matthew a HackRF One. We look forward to hearing about what he learns!
Ten Reasons to use SiliconCompiler – Including SPDX Provenance Support
Zero ASIC’s chief executive Andreas Olofsson has called for “all chip designers” to try out the open-source SiliconCompiler build system, showcasing his top ten reasons for giving it a go – including a provenance feature which supports the Software Package Data Exchange (SPDX) standard.
“We have been working hard on our open source SiliconCompiler build system for a year now and it’s coming together really nicely,” says Olofsson. “I have been doing chip design and CAD development since 1998 (Perl, TCL, make…) and this is light years ahead of anything in the industry. You owe it to yourself to at least...
OsmoDevCall: "Advanced SIM card topics: GlobalPlatform SCP02, OTA, ARA-M, ISIM"

February update: chat with the machine
As the Chinese New Year comes to an end and people return to work, production and shipping return to normal. More units of the PinePhone Explorer Edition, the PinePhone (Pro) keyboard case, the PinePhone Beta Edition and all the other popular products will be dispatching in the coming days.
HyperRAM controller for USB analysis
Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/hyperram-controller-for-usb-analysis.
One of LUNA’s core features is the ability to perform protcol analysis of USB 2.0 low-speed, full-speed, and high-speed. For most target devices, LUNA can endlessly stream the capture directly to a host PC over its own high-speed port. However, for high-bandwidth target devices that can’t be streamed in real-time, LUNA has 8 MiB of memory on board to buffer captured data before sending it upstream.
On LUNA we’re using HyperRAM, a type of pseudo-static RAM, which is capable of achieving relatively high speeds while being much simpler to...
Присматриваемся к одноплатникам на RISC-V, обзор модуля Sipeed Lichee RV на процессоре Allwinner D1
Одноплатные компьютеры на RISC-V процессоре сравнительно новое веяние. Поднебесная активно работает над снижением зависимости от западных информационных систем и технологий, именно поэтому новая открытая архитектура RISC-V одна из ключевых ставок Китая. Для продвижения в массы китайский чипмейкер Allwinner на базе ядра Alibaba/T-Head Xuantie C906 RISC-V разработал процессор Allwinner D1 и упрощенную модификацию Allwinner D1s. На сегодня разработано несколько одноплатников на RISC-V процессоре, и в первенство по массовости вырвалась компания Sipeed с модульным компьютером Система-на-Модуле Lichee RV с 512 Мб ОЗУ всего за $16.90, работающим на Linux. Разработчик может спроектировать несущую плату для данного модуля, добавив необходимые периферийные устройства и разъемы. В...
PinePhone community poll results
Throughout January we ran a poll asking people about how they use their PinePhones. Some poll results are quite predictable while others yielded unexpected results. Before we start, let me put on my academic hat for just one minute.
