Re: Need help to identify a component marked "SF"

Hugh! I couldn't find ANY of these sensors locally.
Had to order an HW-108A from China...
I will post a (hopefully success) report when it arrives!

Thanks a lot for your help!!! :)

Re: Need help to identify a component marked "SF"

João, you're right. I mixed up the wires.
Previous picture is updated with actual voltages.

Yes, the points marked GND on your picture seem to be correct.
Points marked "+V" are 5v.

Re: Need help to identify a component marked "SF"

Hmm... With the sensor taken off, there are about 10v on each pad.

None of them is GND - at least not the fan GND.

Re: Need help to identify a component marked "SF"

Gents, you're right! I just looked at the fan again, and this element is definitely installed in front of rotating magnet. That's why there's a hole in the PCB. CYSH12AF looks very similar to the one that was installed. In fact, there are lots of similar ones here: www.cy-sensors.com/CY-HallEffectIC...

My part looks similar to sot23-4. And that Ricoh looks quite different... I guess it's not that thing.

Re: Need help to identify a component marked "SF"

I also thought it's a kind of an RPM sensor. Maybe something like this ? Though, the fan doesn't even start without it. :( P.S. These are not burn marks, this is some flux and a permanent marker (probably a leftover from the factory). I cleaned it with some alcohol, and it all looks fine in that area.

Hi All, Unfortunately, I wasn't careful enough while taking a cooling fan apart (I just wanted to clean it and replace the bearings...). This is a 4-wires 12V cooling fan with quite a lot of electronics inside. Unfortunately, there are no stickers or markings on the fan itself, so I don't know what ...

Hi All, I'm seeing a minor issue with Telemetry Logging configuration. In the radio, I can browse through the logging rate options like this: 1.0s, 2.0s, 0.5s. I think it's better to sort this list, starting with 0.5s. In eepskye I can only see 1.0 and 2.0, but cannot see 0.5s at all. Also, in eepsk...

Re: FrSky M9 gimbals in a 9x - photos (traffic!)

Sorry, can't help much with the sensors as I didn't follow that market. I guess it may be difficult to find a suitable sensor operating at 5v. But I can be wrong.

Why do you want to downgrade back to the stock mainboard? In my opinion, AR9x is so much better!

Dear All, I got an ARUni board that 'almost' doesn't work. Previous owner tried to install it into his radio, and he couldn't get it to work - so he gave it to me.

Thanks a lot, Mike!

I can't seem to find any source for these (ebay / aliexpress are of no help, either). Do you know of any replacement that could fit? Or maybe a store that offers the AM5521C itself (preferably in quantities of less than a reel...)?

Re: RSSI and qx7 using xm plus

As Kilrah said, XM / XM+ do not have telemetry. Though, they do transmit RSSI on Channel 16 (or on Channel 8, if you install corresponding firmware). The RSSI value has to be processed by the flight controller and then can be shown on the OSD (if you have an FPV system). There's no way (that I know ...
