Note: An electronic module is a pre-assembled kit. It consists of an instruction pamphlet and a completely assembled circuit board. The instruction pamphlet contains information for using the module. The aim with the modules is to save the end user’s time since all the electronic components are already soldered onto the PCB. It supports the concept of modular electronic system design.
