PICOVEND EZ MASTER

What is this device?

It is a fast and reliable board, based on a performant microcontroller, ready to connect to any MDB payment system. You can use it for fast vending machine development. Using this device, you can easily move forward with your vending machine development, without spending time to solve the MDB payment systems management.

You only need to get familiar with a minimum set of information regarding the MDB cash and cashless transactions flow and you will not need to learn anything about MDB low level protocol, timings and CRC calculation.

This device can be used together with one or several PICOVEND EZ ESP 8X modules (8 relays module), to allow direct control of 8 to 64 external electrical circuits. For example, it can be used to control, using a single payment point and payment systems set, up to 64 washing machines, dryers and other equipment, for a self service laundry solution.

This device is ready for the market. Send us an e-mail if you need commercial details.

How it's working?

That is easy, you need to configure the device MDB master parameters and you are good to go. The device can handle MDB coin acceptor/changers, bill validators/recyclers and cashless devices It can emulate the MDB block of a vending machine with Level 2 or Level 3 options for cashless devices, including always idle function.

It can be used as an USB to MDB master (connecting MDB payment systems to USB) or MDB master to RS232 (connecting MDB payment systems to RS232). Can be used with a computer, an Android tablet or other device supporting USB host/USB OTG/RS232

We are also offering an USB to MQTT bridge (needs Java), that can be executed in background, in order to allow connecting the interface directly to an MQTT broker, either local or remote. You can simply configure an MQTT broker (for example mosquitto). Then, by executing the Java bridge we are providing, you no longer need to handle the serial communication. All you need is to subscribe and publish to the interface input and output topics and use MQTT libraries in your preferred programming language.

What you need to do?

Almost nothing. You need to only set the correct working parameters, connect it to the payment systems and start writing your vending machine application. You only need to take care about your vending machine business flow, user interface and other functions and forget about MDB payment systems handling.

After initialization, you will be able to use a simple ASCII protocol to handle cash and cashless transactions, receive money, recharge cashless devices, etc.

Can I go deeper on the MDB protocol?

Yes, we can develop some custom peripherals if your project requires that and we can even create a custom firmware, upon your needs.
