I'd happily take one of these prototypes (I'd assume all features are tested and it's the same as the final version?).
@bdring do I need a special branch of Grbl_ESP32 to run this board with TMC5160 and SPI? Or has this been integrated in master?
pls ignore my last comment, I found CPU_MAP_SPI_DAISY_4X in the map on master
I'm very impressed with your board. Also with your code. Thanks a lot! The steppers work fine on my 3 axes, but I'm unable to trigger the relay. The interlock...
I've soldered the pin but the relay is still not working. I've verified GPIO 25 (Spindle_3v3) with a multimeter, and it toggles from 0 to 3.3V when being turned on...
Applying 5V to JP5 operates the relay, so apparently there is an issue with the TXS0101. From the datasheets, the voltages at the pins should be fine. But I'm unsure...
 Yes, I have both jumpers connected as shown in your picture. I just had removed the interlock when taking the picture as I was also measuring on those pins.
With both jumpers removed, when spindle is on, I get the following readings: G25: 3,18V G4: 3,17V Inner side (closer to C4 pad) Interlock: 0,002V
J3 5V shows 4,95V
Ok, thanks for the hint, I will try that. Can you tell me the exact part number for the shifter (same package/footprint etc), then I'll attempt to replace it.
