8$ iCE40 developer board..

(1/30) > >>

aventuri:
i've just found this Upduino board, a Lattice iCE40 based design for less then 8$ shipping included!! tell me about cheapness..
BTW it looks like an Ultra Plus version of Lattice FPGA with ~5K LUT  and boasting 8 MAC/DSP cores, 1Mbit of added RAM, I2C HW cores. it's a beefy IC (with respect to Lattice lineup, of course..)
 
it's also promoted by Lattice Semi itself..  that's a kind of an endorsement!
 
two one downside:
* you need to stick with Icecube2 for design, as it's still one of the few iCE40 devices still not supported by the free toolchain arachne-pnr/icestorm..
* there's no programmer on board and so need a Raspi or similar SBC with SPI port.. not a big deal..

there's schematic and all, so pretty documented project

finally this board CAN be programmed with the free toolchain Yosys/Arachne-pnr/icestorm!!

looking at the Linked-in page of the owner of the site, i would say he's a Lattice "insider" and these boards are heavily subsidzed, but it's just my speculation..

me, i'm curious so i've committed for a couple and see how they fares.. eventually put up a post at the right time
 
bests

EDIT: updated with the fact that the free toolchain based in Icestorm is able to program these parts too!!

Nice!

What's wrong with Icecube2?
