LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Gotta luv the folks at GOWIN SEMI, straight out of the manufacturer's jewelry box. Top silicon guys, highly recommend.
Official, we have our FPGAs secured, what will eventually power this LinuxCNC-RIO awesomeness!! We have 3 parts (for now). And I want one

Cool visuals ritual;

Hi,
i can not download the board-images (TOP-View), can you upload it directly in the forum ? i will start adding it to the rio-setup

EDIT: I managed to download the image

Great stuff, on the 5AX outputs, how many mA do you get at the outputs connector?

Not much I would guess, granted you only use the GND, Step and Dir pins (common drive set-up). Fwiw the 5V supply of the board is 2A. Using a MPS part (MP4560). Side note; strangely enough my datasheet rev claims MAX 60V where the MPS' revised/latest one claims 55V. Guess we can assume it's good enough up to 48Vdc psus. (Board's 5V switcher schematic attached).

My set-up, powered straight out of the board itself: 

4 relays = 120mA each
1 spindle rotary encoder = 90mA
1 MPG = 65mA
1 PROBE = 45mA
Total = 680mA

If other sensors are required (eg. several linear scales, anything power hungry) then I'd recommend them to be powered externally via 5V and common ground. 

Thanks, on a STEP pin, I assume it can it push enough mA to drive an opto-coupler inside the "generic" stepper driver that you get for say a NEMA34 size?

initial config's for your new board:
 

but only image and pin-locations, need to add the real FPGA-Pin names and the board needs a name,
i think you wrote a name somewhere but i haven't found it yet

EDIT: is there an LED Pin ????

Yes of course. One pin of the 7760 can put up with up to 10mA.

Ahhhhhh sweet, thank you so much!!!! That'll make things so much easier. Geez I need to learn how those pinouts are done, haven't got to the rio-setup part much yet

Only LED atm is the FPGA "Done" pin. You told me to add one and I forgot. The art of doing stuff in a rush on display... my bad. Let's add one for Rev 1.1

the board files are actually quite simple:
github.com/multigcs/riocore/blob/dev/rio...ecanix5ax/board.json

the only thing missing there are the fpga pins
