Raspberry PI vending shield (RASPIVEND DIRECT)

(active product - samples available on stock)

This device manages all MDB critical tasks (9bit to 8 bit conversion and back and 5ms ACK/NACK answer). The entire logic is performed by the daemon, at the OS level. It has no limit and supports raw MDB messages exchange, so the user's application can implement any desired MDB functions.

We have started the development of this module folowing two objectives:

1. Building new vending machines, with a touchscreen, based on any Raspberry PI compatible SBC
2. Upgrading any old vending machine, with a touchscreen, based on any Raspberry PI compatible SBC.
Can be connected on any 40 pin Raspberry PI compatible SBC (ex. Banana PI, Orange, PI).
Additionally, this device can offer full telemetry and remote control over the Internet.

It offers the following functions:

  • MDB port, to connect any MDB payment system (bill validators, coin acceptors, coin changers, cashless devices, etc.);
  • ccTalk port, to connect any ccTalk payment system (hoppers, bill validators, coin acceptors, bill recyclers, etc.);
  • Two RS232 serial ports, to connect any RS232 peripheral (printers, ccNet payment systems, etc.);
  • 40 pin Raspberry PI compatible port. This port will also supply the 5VDC/2A power for Raspberry PI;

Using this module there will be very easy to build any touchscreen based vending machine, or upgrading any old machine.

We are suplying a binary daemon application with libraries for MDB, ccTalk and Raspberyy PI GPIO handling, which are based on Python 3 (required to work) and PySerial 3.0.1 (tested also with PySerial 3.2.1 and 3.3)
