I²C Bus
I²C (Inter-Integrated Circuit) is a synchronous, multi-controller/multi-target bus used for communication between sensors, chips, etc.
SPI Interface
The SPI bus on TOWER: the SCK, MOSI, MISO and NSS signals and their Core Module pins P12 to P15, with the LCD Module as an example of an SPI peripheral.
UART Interface
UART on TOWER: the three channels UART0 to UART2, baud rate, data, parity and stop bit settings such as 8N1, and logging on UART2 at 115200 baud.
USB Interface
USB connectivity options for the HARDWARIO TOWER Core Module, Radio Dongle, and Bridge Module.
1-Wire Bus
1-Wire is a serial bus that uses only two wires for half-duplex bidirectional communication with multiple 1-Wire slave devices.
