Produktbeskrivning
RasPiComm är en liten expansionsmodul som utökar Raspberry Pi med en mängd seriella kommunikationsinterface, en realtidsklocka med batteribackup, 5V toleranta, digitala I/O-pins (Raspberry Pi's GPIO-pins är begränsade till 3.3V) samt en liten joystick!
Specifikationer:
RS-485 serial channel up to 230400 baud, pluggable screw terminal connector (A, B, Gnd)
RS-232 serial channel up to 115200 baud, pluggable screw terminal connector (Rx, Tx, Gnd)
RS-485 & RS-232 pins are fully ESD-protected by TVS diodes
Real Time Clock/Calendar, battery included powers the clock for approximately 10 years
5 x digital Inputs connected to onboard joystick (4 way + push), 5V tolerant, 2mm pitch external connector, not populated
2 x digital Outputs, 5V @ 100mA max each, 5V relays can be connected without additional circuitry, 2mm pitch connector, not populated
SPI serial channel connector, 2mm pitch connector, not populated
2 x I²C serial channel connectors
Power connector, pluggable screw terminal connector (+, -) either powers the Raspberry Pi and RasPiComm (5V @ 1.5A max) or is a power output when powered over USB
Power consumption: 10mA max (outputs off), 210mA max (outputs on and maximum rating drawn)
Storlek: 35.2 x 56mm
