OpenHarmony development board borrows BBC Micro:bit edge connector

OpenHarmony development board BBC micro bit

HopeRun’s HiHope development board features a HiSilicon Hi3861V100 32-bit RISC-V microcontroller compatible with OpenHarmony OS and looks very much like the BBC Micro:bit educational board notably with its edge connector. The board is also designed for youth education (in China) and comes with similar sensors, but there are some differences such as a 0.96-inch OLED instead of an LED matrix and support for offline voice recognition. There’s no wireless connectivity apart from NFC support. HiHope board specifications: MCU – HiSilicon Hi3861 32-bit microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory Display – 0.96-inch OLED display with 128×64 resolution (SSD1306) Connectivity – NFC with R/W mode, card emulation,  and bidirectional mode USB – 1x USB Type-C port for power and programming Sensors – Temperature & humidity sensor, light sensor, microphone, 6-axis motion sensor Expansion – Edge connector with 5x rings (3x […]

Ubuntu Kylin 20.04 OS works on RISC-V hardware

Ubuntu 22.04 Kylin OS RISC-V

China-developed Ubuntu Kylin 20.04 is now supporting RISC-V architecture with an image for HiFive Unmatched mini-ITX motherboard, and work will be done on an unnamed Starfive SBC that should be the VisionFive board with a GPUless JH7100 dual-core RISC-V SoC or an upgraded version with JH7110 SoC featuring an Imagination IMG BXE-4-32 GPU. You may have read recent reports about China asking government entities, including state-owned enterprises (SOE), to replace foreign hardware and software within a two-year period. So that means avoiding systems based on Intel and AMD processors, so working on RISC-V open architecture makes perfect sense, since over time, Chinese manufacturers should be able to make RISC-V SoCs and PCs based on those processors, albeit probably not within the next two years at any significant scale. Ubuntu Kylin 20.04 RISC-V, as well as the newly released Ubuntu Kylin 22.04 x86, can be found on the English download page […]

COVID-19 outbreaks and lockdowns in Shenzhen and Hong Kong delay some projects

Coronavirus manufacturing china

This may read like January or February 2020 headlines with disruption to shipping and manufacturing in China due to a “new coronavirus”, but it’s happening again, particularly in Hong Kong and Shenzhen where COVID-19 case numbers have jumped and the governments have implemented strict measures to attempt to contain it. Since Shenzhen is a hub of electronics manufacturing and Hong Kong is often the gateway to those goods, we’ve received several reports of disruption and delayed projects. First, from Source Parts saying the Popcorn Computer will be further delayed in parts due to the COVID situation in Shenzhen: …Within a short period of time after cases suddenly began to rise, we noticed that more apartment complexes were undergoing mandatory lockdown. We started to stock up early on essentials including food and water. One day, the two nearby food markets we frequent were fully stocked in the morning and empty in […]
