MDB Pi Hat VMC

The Qibixx MDB Pi Hat VMC is a reliable and universal MDB solution that, when combined with a Raspberry Pi can serve as a Vending Machine Controller.

This device combines the MDB Controller, which can be used to control several peripherals as defined in the MDB Specification, with the I/O Capability that can be used to control the vending Machine Mechanics and read Inputs from sensors or similar devices.

It is an all-in-one solution for the handling of both MDB Peripherals and the VMC of the operation, making it a cost-effective product to design a fully customized vending machine.
