Questions about TMP117 sensor

Hello. I have a few questions about the TMP117 qwiic connect board. First, are you able to remove the connectors from the board, to reduce bulky ness? Second, how would you wire this sensor to a Sparkfun Arduino Pro Micro, as it does not have qwiic connectors. Finally, is there any example code for this sensor that works with a pro micro board? Any help would be greatly appreciated! Thanks!

are you able to remove the connectors from the board, to reduce bulky ness?

You could desolder those connectors, but you're going to need a hot air station to do it. If you attempt, I'd heat the board from below and then tweezer the connectors off rather than heating from above. If you heat from above, the plastic connectors will likely melt or burn making a mess of the board.

Second, how would you wire this sensor to a Sparkfun Arduino Pro Micro, as it does not have qwiic connectors.

You'll want a 3.3 volt Pro Micro for this, the 5 volt one will fry your sensor. Just use the pads on the edge of the board for power, clock and data. On the Pro Micro, SDA is pin 2 and SCL is pin 3.

Finally, is there any example code for this sensor that works with a pro micro board?

The same code we use for the Uno should work no problem with a Pro Micro.

Would the board get fried with a 5v pro micro? The page for the TMP117 says that it can take up to 5.5v, so I thought it would be fine

Looking at the schematic, it should be fine running the board on 5V. Just make sure you don’t connect it at the same time to any qwiic or other 3.3v boards as most of those won’t like running at 5V.

Good catch, I missed that!

Yes, in this case you’re OK because this particular part is 5 volt tolerant but like Mike mentioned, most Qwiic boards are 3.3 volts only and 5 volts would be a no no. :slight_smile:
