The Pi Hut

UPS Module 3S

This Uninterruptable Power Supply (UPS) module takes three 18650 lithium-ion batteries (not included) and offers a regulated 5V supply with up to 5A continuous output alongside a 3.3V output and host of other useful features - perfect for the Raspberry Pi. The module supports simultaneous charging/discharging and can p

Amazing! appreciate if you share with us in the community how long RPi5 + AI Hat lasts on such portable batteries. I always powered them using a dedicated power supply or an adaptor.

@pallavaggarwal or @Umesh Lokhande would be good resources.

I was looking at Pallav's blog and there's some brief mention of it but nothing in depth. Do you have any specific questions or just looking for an overview?

Umesh Lokhande•11/27/24, 3:03 PM

There are generic steps you can follow to stay compliant with the latest RoHS directives that can be found online e.g these blogs
- https://tetrainspection.com/rohs-compliance/
- https://environment.ec.europa.eu/topics/waste-and-recycling/rohs-directive_en
Not-so-popular advice is to consult compliance experts or certification bodies in the target geo in the specific product segment like in ur case wireless technologies.

This will surely increase the risk for tech entrepreneurs. But the next question is what about service providers who uses AI to fulfill their EU clients All together will slow down innovation.

madness•11/28/24, 1:47 PM

there has never been a better time to get into rf. you can buy budget spectrum analyzers and vector network analyzers for like $100, where a used one used to cost $5,000 and up, meaning, the equipment you need to understand, measure, and work with RF is actually attainable now for anyone. also there is so much info online now, youtube and such, and so many cheap development kits. all you have to do is give it the time it takes to learn and understand and it will all come together. it will also open a whole new world because it applies to anything that is AC. even looking at reactive power on the grid at 60 hz, that's not rf but you would have a better understanding because the "magical" things happen when you go from dc to ac.

true, it is great time for it.
but there are still lack of open source resources in terms of models for designing these cicruit

for one instance, we were working on creating a half duplex RF circuit on ADS and genesys. where most of the time went on stalling due to many people not having the required models for few IC such as LPF and Amp with them. we had create custom one from there...
