Hi Terje,

As I happen to have a Nucleo with a STM32F411RE onboard, I figured I might as well put it to good use running grblHAL.

Did you, or anyone else had these made, and perhaps have a few to spare?
As I am not too familiar with Kicad beyond the title of the program, is there a parts list I might use as a shoppinglist?

Festive regards!

I have a few unpopulated boards to spare from the first batch. There is a fixable layout error for PWM > 0 - 10V spindle control. Trinamic drivers controlled by UART (TMC2209) or SPI (TMC2130) cannot be used either. A couple of Euros per board and postage at cost is reasonable? I can add a mylar solder paste stencil too if required.

I have not yet made a parts list but that can be extracted from the KiCad files, on my todo list.

I am about to make a new batch with Trinamic driver support and improved PWM -> 0 - 10V spindle control (faster optocoupler, layout fix). Sensorless homing will not be supported for TMC2209 due to lack of pins. TMC2130 may get support for sensorless homing as these have an open drain output that be wire-or'ed together.

Happy holidays!

Hello Terjeio, thank you so much for the outstanding work you are doing, a real labour of love. I'm keen to buy a couple of populated boards when you have them available.
Cheers
Mike

I am not planning to sell populated boards as I have to solder up the few unpopulated ones I have myself. See the bottom of the readme for details.

Yesterday I finally completed verification of the new batch mentioned above, I have just updated the repo with the latest version that has one resistor added for the I2C keypad strobe input.

@jappiemike Sorry, I have completely forgotten you - the local shop did not have any envelopes for shipping and after that this went off my radar. If you still want the boards P&P is EUR7. Since you wanted 3 I assume it is the v1.0 version which are free. Payment will be to my Paypal account.

Ran into this project and was curious if the boards (Rev B or C) still and how to get them if they still exist? I'm in the EU.

@nebulorum They are still available, payment is via Paypal. I need the quantity to calculate postage - will post a comment with the Paypal account then. Nota thate the boards are bare - you have to get the components and solder them yourself.

Would work for me but we need a way to direct message. Issues are not a good place to put personal data :)

I was also wondering if you can't use a Group Buy (like in mechanical keyboard) to do a run of Rev C with SMD already added.

If someone is willing to do that it is ok for me.

I know ive been in the other discussions, but I just found this. Are there any bare boards avail? Partslist? Did you get pwm issue resolved I saw a few posts back?

@customsolutions I still have a few boards available. A BOM can be generated from the KiCad project, I made one earlier but do not have access to it now as I am on an extended holiday.
The PWM issue is with the PWM > DC conversion circuit on the first revision of the board and can be fixed by modifying it.
