Olimex PIC MOD Modules
- Olimex MOD-RS485, The Olimex MOD-RS485 is a half-duplex RS232 to RS485 converter with a UEXT interface for microcontrollers which is based around the Analog Devices ADM3483ARZ. This module is an excellent choice for communications over long distances & in electrically noisy environments with multiple devices in a multi-drop configuration typically over twisted pair. The data rates achievable are inversely proportional to the transmission distance. Uses SPI to communicate to the MCU Olimex MOD-RS485 RS485 UEXT Adaptor Module
