a. The issue is fixed as per: https://www.raspberrypi.org/blog/poe-hat-revision/
I should have checked that first, right up at he top it says in bold they are the new ones with the new filter hah, thanksmartinrowan wrote: ↑Mon Nov 26, 2018 2:44 pma. The i1ssue is fixed as per: https://www.raspberrypi.org/blog/poe-hat-revision/
b. The new boards are in the channel, I can't say if Amazon sellers are selling the new or old boards, in theory they should have returned all the old boards, but there's no guarantee. You might need to contact the seller. The PiHut (UK) are clear on their page that it's the modified version: https://thepihut.com/products/raspberry ... et-poe-hat
I'd expect other major distributors such as RS and Pimoroni to be selling the updated fixed version.
I don't believe so. Best to return the original board for a replacement.
First thing I would try is a 100 ohm resistor between 5 vols and TSOP and a 10uF capacitor from junction of resistor and TSOP to ground.DaPeace wrote: ↑Mon Dec 03, 2018 6:44 amIve ordered the new revision of this board after i had problems with the ir-tsop with the old revision.
I want to use a rpi3b+ with poe-hat and ir-tsop as a sat-ip-receiver.
Unfortunately this is not working with the new revision as well.
Every time when the fan starts, it seems to induct some spikes into the 5v-line and the remote/ir-diode stops working.
It seems that the ir-tsop is a little sensitive to those spikes. When the fan stops, the remote starts working again.
Another problem is, that the poe-hat seems to heat up the rpi so the fan is really necessary. Ive tried without the fan an the rpi heated up and showed the thermometer-icon in the top right corner.
The tsop is connected to 5V, Ground and GPIO18.
Any hint how to solve that?

So presumably USB cameras. If you power via a normally attached PS, does the flickering still happen, or is it specifically down to the PoE power arrangement? Multiple USB camera have been reported as sometimes being erratic (a consequence of the HW USB implementation on the SoC itself), so would be interesting to show if it is the PoE or not.
