Recently, 2 new development chipboards were launched for the open-source Huawei HarmonyOS operating system –OpenHarmony. This launch will further improve the community backbone, and the OpenHarmony chip/development board platform has been further enriched.
So far there are 20 chips/development boards have been integrated into the OpenHarmony backbone, and the OpenHarmony ecosystem continues to grow.
The integration into the backbone means that more community developers and partners can build, improve and enrich various functions around the chip, and build more development versions covering different solution scenarios and categories.
For developers, it can greatly reduce the development threshold of OpenHarmony, which is convenient to develop at a lower cost and experience more of the latest features of OpenHarmony.
For enterprises in the industry, it greatly reduces the OpenHarmony development cost of chip adaptation. Hence, developers can quickly and cost-effectively create their own products, and more flexibly adapt to various terminals, jointly promoting the digital and intelligent transformation of the industry. 
It is reported that the 2 development chipboards of OpenHarmony are the KHDVK-3566B development board launched by Shenzhen Kaihong Digital Industry Development Co., Ltd. Digital Industry Development Co., Ltd. (referred to as “Kaihong Zhigu Company”) is a Niobe U4 development board based on ESP32 series chips.

Youbo Technology cooperation has launched a new OpenHarmony-based UB-RK3566 processor. The chipset is mainly developed for IoT (Internet of Things) applications and smart devices.
According to the latest information, the OpenHarmony-based UB-RK3566 processor supports powerful functioning and brilliant performance on the surface. Besides, it is also eligible for high-end display engines and other technologies.
Further, the latest Youbo chipset is uprooted on an A55 process structure. It holds an ARM G52 2EE GPU and also supports a dual-screen display. Alongside tech-pack elements, the chip also uses a self-developed JPEG decoding microprocessor.
In terms of functions, the UB-RK3566 processor is capable of showcasing 1080 at 60 fps resolution, H0264, and H.265 format encoding, supports dynamic rate, frame rate, resolution adjustment, and many other display-related features.
On the other hand, the processor can efficiently work in dual-camera scenarios. Ultimately, operators can have a crystal clear image with effective lighting due to the UB-RK3566 chipset.
You can check the major functions, below:
- High computing power with less consumption: The processor installs a Rockchip RK3566 quad-core 64-bit Cortex-A55 unit and can easily support up to 0.8T computing power. Besides, it improves the battery life of devices
- Seld-developed display chips: The processor already holds finer display chips to reduce the excessive cost of display components. These chips can bear 2200 x 1650 resolution
- High-definition display: Since the processor has high-quality display chips, it offers an immersive virtual experience. It also supports HDMI 4K resolution at 60Hz, 1080P resolution at 60Hz, and more
- Complete display interface: the latest processor supports HDMI2.0 interface, supports dual-channel MIPI DSI, and can drive a 2.5K LCD screen. It also holds Eink, and can directly drive the ink screen.
- Rick Interface expansion facilities and Strong network wireless connection.
These functions make the processor compatible with high-end IoT applications and work conveniently without creating any hindrances in performance or functioning.

Runhe Software HiHopeOS (based on OpenHarmony) has received a new China UnionPay financial and digital service certificate. Eventually, this certification will make the respective OS compatible with the China UnionPay technical specifications.
To begin with, the China UnionPay cooperation is releasing new configurations for digital service devices. Accordingly, these devices require an operating system that can be eligible with the latest technologies and specifications.
Consequently, to obtain a suitable operating system, China UnionPay carried out a qualification program. A variety of operating systems entered into this scenario. However, the OpenHarmony-based HiHopeOS financial release version is the first product to get the China UnionPay certificate.
To be mentioned, HiHopeOS distribution consists of multiple variants for different scenarios and operations. For instance, the IoT Edition for operating lightweight devices and gadgets.
As of now, the HiHopeOS financial version has gained digital service certification. This development will help the Runhe Software cooperation to indulge with more ecological partners and expand the HiHopeOS ecosystem in more sectors.
Digital Service Certification
It’s worth mentioning that the latest digital service certification was based on the following major aspects:
- Basic requirements of the operating system
- Interface layer requirements
- System service layer
- Security functions and technology
- third-party library components
According to the outcomes, the HiHopeOS effectively meets all the points and is reliable with digital services and other high-end devices.
New developments with HiHopeOS
So far, Runhe Software has integrated with various industrial groups and partners to stretch the manufacturing of new products. Besides, the company has associated with several tech makers for smart inventions.
Up to this point, the company has developed smart POS, MPOS, code-scanning machines, cloud speakers, recorders, and many other useful products. Notably, these techs involve the HiHopeOS in their internal structures.
Alternatively, the new achievement of HiHopeOS will help Runhe Software to build a firm partnership with China UnionPay cooperation and develop more new products and services for consumers.
