Luos-io/luos_engine
Open-source and real-time orchestrator for cyber-physical-systems, to easily design, test and deploy embedded applications and digital twins.

The ST3485ECDR is a RS 485 , RS 422 IC made by STMicroelectronics in a SOIC-8 package with 8 pins. 0℃~+70℃ 1 1 12Mbps 3V~3.6V 64 Half-Duplex Transceiver SOIC-8 RS-485 / RS-422 ICs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SN75176ADR-MS, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 3,331 are in stock at JLCPCB (part C81185). 3 open-source boards in 1 repository on GitHub use it.
