MVFD Serial Backpack

With MVFD Panel requiring substantial amount of pins it becomes really first priority to minimise the number of GPIO and processor’s resources for some projects. That is where MVFD Serial Backpack comes to play. It takes responsibility of communication with VFD panel and conveniently provides either I2C or Serial interface to the main controller. Very useful when the number of available GPIOs or microprocessor resources is limited or when there is a need to build a working prototype with minimum effort. The circuit diagram of the module is given below.

The PCB layout is done on two layers with dimensions less than 50mm x 50mm which allows to be within limitations of ‘light’ Eagle license and take advantage of 50mm x 50mm PCB manufacturing service from ITead Studio. Component placement for top and bottom sides are given on the pictures below.
