Description
The KAmodRPi UART RS485 ISO is an RS485 bus transceiver controlled from a UART interface, compatible with the Raspberry Pi SBC family. On the RS485 bus side, the MAX13487 chip is used, which features automatic transmission direction control. This solution requires only 2 signals - RXD and TXD for proper, two-way communication using the standard UART interface. The control signals are connected through circuits providing galvanic separation. Additionally, the module is equipped with surge protection on the RS485 bus lines and allows the connection of a 120 Ω resistance serving as a terminator for the RS485 bus.
Features
