Base board of the SQM^®4 development platform, compatible with all our modules. Featuring the down-pins female socket, the down-pins variants of the modules can be easily attached/detached to/from the base board, allowing for effective development on different SQM^®4 modules.

The board expands a high number of peripherals available on SQM^®4 microcontroller/microprocessor module, whichever you choose. It provides the right way to start an immediate development of your own devices based on the SQM^®4 modules. EasyBoard demonstrates in practise how use of SQM^®4 modules rapidly simplifies and cheapens the whole development and production process because the base board can be so easy. YES, EasyBoard really is a two-layer only board! And since the number of peripherals in embedded applications is not usually so high, your device can be even simpler, fast to develop and cheap to produce. It can be so easy!
