MDB Pi Hat USB

Overview:

The MDB Pi Hat is the first generation of Qibixx MDB to Serial Adapter with a Raspberry Pi Form Factor, and is now also connectable through USB, to free up the 40 pin header for other applications, if necessary. It can be used as a Master/Vending Machine Controller (VMC) or a Slave/Peripheral in the Multi Drop Bus (MDB). These features allow to implement a custom VMC, simulate cashless devices and virtually any application that needs to communicate with the MDB bus. 

Features:

• High level functional interface for cashless device implementations;
• Independent VMC and Peripheral interfaces;
• Easy jumper configuration to select power supply to the host (Raspberry Pi or other) and MDB operating mode;
• Firmware update capable;
• Universal MDB Interface in Pi Hat form factor;
• USB Optional connection, configured with a Jumper;
• USB compatible with most common Operating Systems (macOS, Linux, Windows);
  
• Precise, time-stamped sniffing from MDB bus;
• High-level, easy to implement serial interface protocol;
• 2 years warranty;

Power Requirements:

• 3.3V DC if supplied by the Host (Raspberry Pi or other);
• 20 .. 42,5 V dc from the MDB Bus as defined in the MDB Protocol Specification;
