I am attempting to connect a Sensair co2 sensor, a Sen55, and a Mics 4514 to a wesp32, the later revision. I have multiples of all components here and have swapped all out, one at a time to no change. I have tried one sensor at a time. The I2C devices are “not found” on either bus or on multiple different suggested frequencies, and the uart sensair routinely throws the error about it “taking a long time” and none of the sensors report back any information. The components are powered off the 12v power supplied by the board through a step down voltage converter set at 4.9v to 5v under load.
The code I am using:

Any ideas on my problem?
Both the I2C scans doesn’t find any devices, so I would start checking the wiring. I don’t have a wESP32 myself, but if I look at the pinout scheme at Hardware - wESP32 — Wired ESP32 with PoE I get the feeling that you are mixing up pinnumbers and IO definitions. In that scheme pin15 is the SCL and pin17 the SCA. But pin15 is GPIO04 and pin17 GPIO15, so I would change that in your yaml.
Furthermore you are using GPIO17 twice, for I2C and ethernet, that can be correct.
Last remark: Why are you using 2 different I2C busses? The I2C bus is designed to connect 256 devices to one single bus as long as the I2C addresses from the connected devices are unique.

Changed code to, following the link you posted, which I hadn’t seen as all other things, and that page on the site, point to the product brief “for more details” which doesn’t include that table:

Otherwise the use of both busses was for assembly and troubleshooting ease as I was hoping to only use these 3 sensors in this use case. Solder/wire the three sets to their respective places and be done, but here we are.

The Mics is now functional and is reporting, but the sen55 and the sensair is still not
So one off the problems is solved, now the next one. If I look at your YAML, you are using GPI033 twice, (for I2C and UART) and you suppress the message that can help you to identify this problem by using by the “allow_other_uses: true” statement. You should only use that statement if you are really sure you need that same pin twice, and you can only do this if the pin has the same function in both cases. Personally I didn’t see a situation were this is really needed. Doing this for mixing I2C and UART won’t give you a working environment. The pinout scheme is referring to GPIO12 for UART TX and GPIO13 for UART-RX when you want to use the UART0 bus.
Where is the UART0 bus?
