CC3220SF-LAUNCHXL: interfacing RS-485

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC3220SF, BOOSTXL-RS232

is it possible to interface RS 485 with CC3220SF Launch pad ?

Is RS 232 is being documented, but RS 485 is not. Is it possible to interface RS 485 with some hardware changes ?



  • Hi Baskaran,

    At CC3220SF Launch pad is not integrated RS232 or RS485 driver. For both you need to connect external hardware to Launch pad. For RS232 you can choice BOOSTXL-RS232 which should be compatible with CC3220 LP. For RS485 is BoosterPack not available if I am not wrong. You need select RS485 driver chip which best suits for your application (isolated, non-isolated, etc.) and connect it to LP.

    As start you can read this reference design - (I am not sure if this design is fully compatible with CC3220 LP).
