Product Details
The internet of things (IoT) is fast approaching and will affect every area of our lives. This will equally be true for the vending industry. That’s why we have created an MDB Raspberry Pi HAT.
While many vending machines these days are already conntected to the internet, in some cases this is still considered an “add-on”, or a telemetry unit. This means there is an old-school VMC (vending machine controller) that talks MDB. MDB is a 9-bit protocol (yes, you read correctly) designed around a bus where peripheral devices can be attached. It has strict and very short timing constraints. The internet add-on is then either attached to this bus or the VMC.
