This adapter board enables the creation of a stand-alone, network-compatible device using any Raspberry Pi compatible UART daughterboard. The adapter board is used to connect the daughterboard of the Raspberry Pi and WIZ750SR-TTL. The adapter board connects the daughterboard of the Raspberry Pi to the WIZ750SR-TTL. It also provides a 5V and 3.3V power supply where necessary.

The adapter board was initially designed to connect the RaZberry 7 Pro to Home Assistant via TCP, without using a Raspberry Pi as a server. It can also be used with any Raspberry Pi daughterboard that only needs the TTL-UART interface. However, the following README refers to the use of the RaZberry 7 Pro with Home Assistant. It is possible to map three GPIOs to the header, although this has not been tested yet.
