Not sure where i heard about precursor but that thing seems pretty nifty but damn expensive.
Cheers I also have a satslink coming my way.
open hardware devices
precursor
https://www.crowdsupply.com/sutajio-kosagi/precursor
FPGA soft core processor RISC-V
$590, no camera. very hackable
coinkite satslink
seems like the same kind of thing but cheaper $189 and not RISC-V. Includes a QR scanner. hackability unknown.
precursor keyboard looks like a blackberry. Its designed as a fully hackable device. Its almost what I want. Being more open is great but I think its expensive and misses QR scanner. I might add an authentication IC although I don't trust them.
I'm assuming satslink will be actual open source and not pretend open like their other stuff. I have one on order.
leaning towards designing a new device.
Discussion
I'm biased that I like to design my own stuff. But, the precursor got my attention because the keyboard is available separately and sold on mouser. I don't really want to design and manufacture the plastic keys for a keyboard.
The current plan is to build a similar device using the precursor keyboard, a more powerful MCU, but less total chips, limit I/O, and make a software that is small enough to be auditable.
I'm sort of lazy so who knows, but I just ordered some eval boards to play with.
