A professional RS422/RS485 HAT for Raspberry Pi with galvanic isolation and an extensive range of features making this ideal for both industrial and home use.
Some RS485 shields are already available for the Raspberry Pi on the market, but these extensions are not suitable for professional use, because they come without a galvanic isolation between the RS485 bus and the Raspberry Pi.
Without such isolation, damage to the Raspberry Pi or malfunction of the device is possible, because of the large distances of an RS485 bus. Furthermore, a full-duplex mode (RS422) is also not integrated.
Compatible with all 40-pin models of Raspberry Pi, including Raspberry Pi 5, 4, 3B+, 3B, 2B and B+.
Raspberry Pi not included.
