MDB Pi Hat

The Qibixx MDB PI Hat is a reliable, universal MDB Interface which can operate in MDB master as well as MDB peripheral roles. It directly plugs onto Raspberry Pi compatible embedded computers with 40pin ‘HAT’ connector. The device supports both serial as well as spi connections to the host. Firmware update from the host under full software control is possible. The interface can be used for Master, Peripheral, Sniffing and combined applications. Thanks to a message buffering concept, the integration with software on the connected computer is easy to achieve and critical timing of the MDB standard is resolved.

A built-in 15W power supply can be used to power the host (Pi) and peripherals from the MDB bus power. Of course, this function can be disabled.
