Additionally you can power the Pi's through their GPIO headers, which are easier to work with than USB-C when doing something custom.

BONESAWWWWWW posted:I hear that you can power the Pi (not just the 4) from two other pins but I heard somewhere else this is somehow less safe than going through the official charging port. Does anyone know what I'm talking about? I would love to be wrong. That's right, the Pi only has voltage regulation on the USB input so if you power it through other means you need to add your own regulator or be confident that your power supply is well regulated.

Dren posted:The faraday cage idea is one i hadn’t thought of, I like it. I wonder what would happen if I found the wifi chip’s spot on the board and just drilled a hole though it. How about killing the antenna? The 3+ and 4 use a PCB antenna, cutting the traces with a scalpel should make the WiFi inoperable without being too invasive. The antenna is this single trace coming out of the EMI shielding can:

Jeff Fatwood posted:They also forgot to add the 3.5mm jack on it which I only noticed yesterday so lol. Either have to use a TV, display with speakers/speaker out or bluetooth speakers. It's not the biggest deal but god drat it A basic USB DAC would also do the trick if you have a spare port Something like https://www.amazon.com/UGREEN-External-Adapter-Aluminum-Desktops/dp/B087T5H3MQ

brand engager posted:That microcontroller thing seems pretty nice, no broadcom bullshit and they've got docs for the chip available thats a nice change. Yeah I bet this is a trial run for rolling their own higher performance chip for the pi5 or pi6, to get away from Broadcom's NDA hell

Hopefully the Pi5 will just have an m.2 slot on the bottom, assuming the SoC they use has any spare PCIe lanes They've implemented NVMe boot already but it's of very limited use for now since PCIe is only exposed on compute modules

There's a seemingly common fault on those where some of the HDMI pins are erroneously shorted to ground, so you must have got unlucky with QC twice https://www.youtube.com/watch?v=gRNxv2CfLtI Should be easy enough to fix if you have basic soldering gear though

Klyith posted:Kinda annoying that you need an additional accessory hat to use it, rather than a m.2 slot on the back of the board like pretty much every pi-clone has done. Like, I don't know how they're possibly going to fit the heatsink plus a m.2 hat and a normal pi GPIO hat on there at once. the official m.2 hat passes through the GPIOs but yeah a heatsink/fan isn't going to do much with this in the way  also the m.2 hat has to replicate the SWD/UART/fan interfaces since it blocks them otherwise, very awkward

Klyith posted:Cripes it can't fit a 2280? third party case manufacturers can build something that accommodates a 2280 at least per jeff geerlings video the PCIe header is officially only rated for 2.0x1 but the hardware can do 3.0x1 and that can be enabled with a boot flag at your own risk

Klyith posted:Wonder if that's attached to the CPU via PCIe? Which brings up an interesting possibility: a raspberry pi GPIO accessory board for normal computers. https://www.cnx-software.com/2023/10/07/raspberry-pi-rp1-datasheet-block-diagram/ they're running 4 lanes of PCIe between the SOC and the RP1, so the SOC has at least 5 lanes (1x + 4x?) wonder if the inevitable compute module 5 will have the RP1 onboard, or just break out all of the PCIe lanes so the carrier can decide what to do with them

the official case is just a plastic heat trap so it's not great, especially if you aren't running active cooling there's some beefy passive heatsink cases which can soak a lot of watts https://www.tomshardware.com/raspberry-pi/raspberry-pi-cases/edatec-raspberry-pi-5-cases-review-passively-cool

Thanks Ants posted:The reason the Pi is so popular is the effort that they put into making software work properly on it rather than shipping a bag of parts and going "lol you figure it out". If someone else decides to care about distro support on their small tinkering SBC then the Pi has almost no value. pi isn't even the gold standard for ARM distro support, the server-class ARM systems from ampere or whoever have fully upstreamed drivers and UEFI firmware that lets them boot unmodified generic distros exactly like an x86 machine the only company trying to scale that down to cheap SBCs is librecomputer but they're stuck with relatively old chips since they don't have the resources to work on upstreaming newer stuff
