Embedded systems

By SoM or CoM (system-on-module/computer-on-module) we mean ready to use computer solutions with embedded hardware (processor, memory, power supply, PCB and interfaces) and software (OS, drivers, libraries). These solutions provide complete, embedded devices for many applications. SoMs often work with Linux and Android operating systems which are great for building HMI panels which are widely used in medical devices, industrial or home automation, fiscal devices, vending machines or POSes.

How did the SoMs become so popular lately? Isn't the preparation of such projects with single processor cheaper and more simple? Unfortunatelly it is just a mirage. Using simple and cheap microcontrollers may be easy when it comes to hardware. Problem starts when it comes to software. Building a compatible software require much more time and limits the possibilities of developing sufficient user interface. Complete operating systems give much more flexibillity and are free from many problems right on the start. Choosing the SoM based on Android OS, gives us a fully working devide with advanced operating system. Most of the customers say that choosing a complete SoM is cheaper than building device from scratch on same components.

First advantage of SoMs is reduction of time needed to end the project and put completed product on the market. Deployment of standard solution lasts from 18 to 36 months. Deployment time can be reduced to 6-18 months only by using a SoM instead of standard solution. The manufacturer does most of the work with the implementation of software, processor and perypherials. Everything, including PCB, power supply and wireless communication is done by the manufacturer. Implementing high frequency paths, memory buses, wireless connection and a power supply requires additional equipment, documentation and a lot of knowledge. Obtaining these things during the realization of project carries a risk of many errors. Consequences of such approach could appear right after introducing of the product on the market. Comparing not only the costs of components but also development it appears that solutions based on SoMs are much cheaper. It is much easier even for big projects to use ready to use embedded computer rather than solution built from scratch.

Complete embedded solutions are also very easy to maintain. Service and configuration of modules with proper connectors is much easier with ready-to-use SoMs. Extending the functionality by adding advanced graphic interfaces is also very easy to implement. Another advantage of embedded solutions is simplified process of ordering and logistics. Client orders only one product.

Soyter Components offers solutions of four System-on-Module manufacturers (SoMLabs, Grinn, Variscite and Quectel). Our clients can choose from wide range of modules (soldered or with connector) that are compatible with Windows, Android or Linux. Every product comes with necessary documentaton, ready-to-use images of proper operating system and schemes of additional interfaces.
