INDUSTRIAL MODULE FOR MIKCROCONTROLLERS AND SBC COMPUTERS

Abstract

In this paper the development of a PCB module which can be used as an industrial interface for microcontrollers and SBC computers like Raspberry Pi, Orange Pi etc. has been presented. The module consists of 7 relay outputs, 8 digital inputs, RS232 and RS485 interfaces, a mikroBUS expansion connector, an RTC / EEPROM module and a 24-bit AD convertor. The power supply, digital inputs and outputs are designed to work with standard industrial voltage of 24V. Also, all blocks except mikroBUS and RTC / EEPROM module are galvanically isolated which contributes to the module’s robustness.
