At home with 4 nodes and roughly 15m CAT5 cable, first node had 5.1V, while the last one had 5.0V only, i.e. 0.1V drop across 15m. So over 90m I would get down to 4.5 only, which is absolute minimum."},"comment":{"url":"https://api.github.com/repos/PoJD/can-pcb/issues/comments/417860933","html_url":"https://github.com/PoJD/can-pcb/issues/7#issuecomment-417860933","issue_url":"https://api.github.com/repos/PoJD/can-pcb/issues/7","id":417860933,"node_id":"MDEyOklzc3VlQ29tbWVudDQxNzg2MDkzMw==","user":{"login":"PoJD","id":4594087,"node_id":"MDQ6VXNlcjQ1OTQwODc=","avatar_url":"https://avatars1.githubusercontent.com/u/4594087?v=4","gravatar_id":"","url":"https://api.github.com/users/PoJD","html_url":"https://github.com/PoJD","followers_url":"https://api.github.com/users/PoJD/followers","following_url":"https://api.github.com/users/PoJD/following{/other_user}","gists_url":"https://api.github.com/users/PoJD/gists{/gist_id}","starred_url":"https://api.github.com/users/PoJD/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/PoJD/subscriptions","organizations_url":"https://api.github.com/users/PoJD/orgs","repos_url":"https://api.github.com/users/PoJD/repos","events_url":"https://api.github.com/users/PoJD/events{/privacy}","received_events_url":"https://api.github.com/users/PoJD/received_events","type":"User","site_admin":false},"created_at":"2018-09-01T13:47:46Z","updated_at":"2018-09-01T13:47:46Z","author_association":"OWNER","body":"So for voltages drop we have 0.188Ohm/m for CAT5. That is 37.6Ohm for 200m anticipated max length of the bus. For 1 wire only. If we run 3 wires PWR and GND, that would be just 12.53Ohm for that length. If we have power source at 5.1V and want to avoid going under 4.6, that gives max voltage drop of 0.5V. That means max current drawn from the line has to be 40mA"}}
