Display connected to the microcontroller instead of the Linux SoC is an interesting choice

Actually, putting all of this powerful hardware into a custom aluminum enclosure with gorilla glass and then using a 6-bit low resolution grayscale display is a weird choice. I guess they were going for a certain grayscale low-fi vibe?

The "needs verification" and "needs clarification" lines are weird. Like they asked someone (or ChatGPT?) to review some docs and post something, but forgot to review it first.

There's a comment at the bottom about that. Quoting the response:

> From the Linux side, it's a standard framebuffer and keyboard that applications interact with as usual. However, our connection allows the MCU to intercept them and overlay additional content — for example, if the CPU hangs, we can still show a menu on the display and respond to button presses, say for a reboot. This also lets us have a low-power mode with the display still on.

Which sounds reasonable.

Re:choice of display, I'm betting it's for power saving. If you need a better display you can use the HDMI port or DisplayPort USB-C port and just hook it right up to a monitor/TV

I like a device with these kinds of specs and this size, but I'd want all of this and all the hardware on the flipper zero as well. Seems all the RF/radio stuff is gone :/ I'd want at least that and more.

Dual gigabit ethernet + even 6ghz wifi means this will likely work nicely as a travel router, which would mean I might actually carry it. There are a whole bunch of portable server use cases this opens up especially as it seems to have a bit of CPU grunt. My Zero was fun but has languished in drawers.

Most of the power in a display goes to the backlight. Going grayscale and low res wouldn't save much at the same level of backlight brightness.

RF design is very much an art, and the difference between works and works really well without harmonics and noise is a matter of design subtleties and often expensive parts. There are decent SDR setups around $500-700 that are known to be pretty good, but you have to go out of your way to buy them from the actual design houses, because despite being “identical”, the clones are not the same. In RF, the devil is in the…

Which SDRs would you recommend at the $100, $300, $600, and $1200+ price points?

I’m not an expert but I know of a few. Are you looking at recieve only, or transmit/ recieve? What frequency ranges?

Off the top of my head

HackRF one- relatively cheap, pretty good transceiver, lots of crappy clones

USRP B205mini, expensive, fast, closer to pro equipment

I had similar feelings but the comments below about adding an SDR to it with an M.2 slot got me looking a little closer. This has an 8-core Rockchip A72/A53 processor and 8GB of RAM. This is not an incremental improvement over the Flipper Zero, this is something else entirely. Hmmmmm...

It's more like a portable Raspberry Pi with better efficiency and more IO. And hopefully even better mainline Linux support out of the gate. The key question will be how much it costs. Beyond $250-300, it's a lot more of a niche product. Below $250 would be very interesting. I don't think it will be below $300. With current memory and storage pricing, probably $350-400 is more realistic :(

Its got 8gb of ddr5 in it. That's already a huge chunk of $300 - I'm not even sure they will get the BOM down to $300.

I'm guessing it'll be $1000 or so. (Which is good for me. Well above my impulse buy threshold. I don't regret buying my Flipper Zero, because it was within my impulse buy and not regret it threshold.)
