The KAmodRPi UART RS485 ISO is an advanced RS485 bus transceiver for the Raspberry Pi, featuring automatic transmission direction control, galvanic isolation, surge protection, and support for up to 128 modules at a transmission speed of up to 500 kbps, powered by 5V with low power consumption
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.

The KAmod RPI 485&CAN Hat module extends the functionality of Raspberry Pi 5 boards (and others with a 3.3 V SPI interface) with two galvanically isolated RS485 interfaces and one CAN 2.0B interface. The RS485 interfaces are based on the SC16IS752 controller, and the CAN interface on the MCP2515 system. The isolated transceivers used (ADM2483 and TJA1052) increase resistance to interference. Communication takes place via two SPI interfaces, and additional power supply options (from RPi or external 8-32 V) and a stabilized 5 V output allow for flexibility in power supply. The module can be mounted on RPi 5, also with an Active Cooler radiator, and can work with other microcontrollers. The maximum transmission speeds are 500 kbps for RS485 and 1 Mbps for CAN
