Testing Micro USB to Type-C OTG adapters for thermal modules

[frenky]

So I bought a new phone with usb Type-C connector and wanted to use it with i3System Thermal Expert Q1 module.

Xiaomi adapter that I had at home did not work so a bought a few others to see if any of them will work.

TL; DR; Some do.

So far this are the adapters that I have received. Some are still on their way:

TL; DR; Some do.

As annoying as it may be, it's worth trying these adapters in both directions, some may only have USB2 pins on one side pinned.

Very interesting research - thank you.

I guess I must just have got lucky. I bought a random USB-C adapter from eBay (USB Type C 3.1 Male to Micro USB 2.0 5 Pin Female Data Adapter Converter Sync (eBay 322858609571).

I tried it this weekend with a Therm-App camera and it worked fine.

Prior to this I'd only used it as a charger adapter, which is hardly the most demanding of roles.

Good point.

I did it on some bit not all. I'll redo test on all to see if it makes any change.

I bought this CHOETECH adapter and it works with my FLIR One G2.

I forgot to mention that I tested the adapter with a 'Maze' brand phone that I got via Amazon. It's a nondescript mongrel of a phone and, super-irritatingly, I managed to lose the SIM tray slide within hours of receiving the darn thing, so it is absolutely no use as a phone. I've been using it via Wi-Fi as a monitor for my home CCTV system but will probably end up dedicating it to thermal camera use.

Unfortunately it doesn't have wireless charging, or I could run it continuously. I am a great fan of wireless charging, if only because it means I won't wear out the USB socket. I have finally persuaded my partner of the benefits of wireless charging after she destroyed yet another phone by being too hard on the connector. The Maze phone was actually bought as a spare so that when, inevitably, the last one got broken I'd have something to swap her onto. I ended up having to get yet another new phone for her, due this time to my ineptitude with the SIM tray, so I made sure it was a wireless job. Six months on, it's still working

Thanks for this post! I'm looking for a Micro USB to USB Type-C adapter, currently just for charging purposes. I wonder what determines whether an adapter works, and if there are quality concerns?

Some mention a pull-up resistor. What is the importance or necessity of this? I thought an adapter is just making a "dumb" electrical connection between different physical connectors.

Also, there is a fairly big range of prices, from well under a dollar to several dollars per unit. Is there a valid reason for this?
