Embedded motherboards and products undergo high and low temperature tests

As an embedded open-source motherboard solution provider, we design and develop products based on chips from Rockchip and Allwinner, including Rockchip's RK3308, RK3506, RK3562, RK3566, RK3568, RK3576, RK3588S, RK3588, RV1126B, RV1106, and Allwinner's A33, A40I, T113, T153, T527, H313, H618, among others.  

We design, manufacture, and sell a wide range of PCBA motherboards with various performance levels and configurations, which are applied across numerous product categories and industry scenarios, such as:  

Card computers: for office use, programming development, home entertainment, and educational coding;  

Linux servers: private cloud, software routers, NAS, personal web servers, etc.;  

Home smart hubs: TV boxes, smart home control, sensor data analysis, security surveillance, etc.;  

Industrial applications: digital signage, vending machines, robots, drones, etc.;  

Embedded development boards: accelerating validation and development of embedded projects.

The PCBA motherboards developed and manufactured must not only deliver excellent performance but also operate reliably; to ensure this, it is essential to conduct necessary and thorough testing of both the motherboard and the product.

Below is an experimental record of high and low temperature testing for a product, which incorporates our company's RK3568 SOM.
