| Mar 13, 2022 at 19:25 | comment | added | kevin | I should have specified, the noise is observed when this breadboard is plugged in to the car (there is a 12V + & ground in the trunk for a CD changer that I am using for this). I will try connecting directly to the battery terminals today as well. | |
| Mar 13, 2022 at 15:43 | comment | added | Miron | I agree, but the battery voltage is still pretty noisy. An LC power filter would help placed between the MCP chip 5V and M18's Vin, and the arduino connected directly to MCP's 5V (it doesnt need clean power). A similar issue is found in RC quadcopters, which have a noisy battery voltage from powering motors that needs to be clean for analog video transmission to look good. oscarliang.com/power-filter-video-transmitter-fpv-camera Also, try the M18 on its own, with 3 AA batteries to check its noise floor, it might just be a low quality part | |
