I am looking to connect two pressure transducers to the device via the RS485 ports. The pressure transducers need voltage between 9-36V. Is this possible? I’ve found that the nominal operating voltage of the device is 24V, but not much else. Hope someone can help, thanks!

Hello @jaszylu,

I would recommend taking a look at the [key specifications](https://bristlemouth.notion.site/Development-Kit-User-Guides-e9ca1b3c5a1c41c890d0105f2eb7c4b8?pvs=97#02fc5b8c21ec407aa13131f2ad2886c7) under the Development Kit User Guides page.  
Also check out the [Technical Specifications](https://file.notion.so/f/f/ecca0679-b04e-423c-a8e8-21cb7e08d702/021b2da3-61a4-4bd7-aa52-a98daba1a1ca/Bristlemouth_developer_kit.pdf?table=block&id=4ff803e2-7ec8-4907-b70c-8e5ab335f504&spaceId=ecca0679-b04e-423c-a8e8-21cb7e08d702&expirationTimestamp=1737532800000&signature=pbhbnhtZBJ1NrXEM5mvrkqe2Pzvr6OV45cNQFTOL7Vw&downloadName=Bristlemouth_developer_kit.pdf).
