bdring / grbl_esp32_development_controller Goto Github PK

Hello! I'm going to make your version of control borad(https://github.com/bdring/Grbl_ESP32_Development_Controller) to replace my old uno control board, I am trying to make a pcb with SMT,and the seller need ’Gernerates pick and place files‘, and I can not find it in the zip.

Thank you!

According to the output of the TXS0101 IC, the max output current is rated as 100mA.
[ Continuous current through VCCA, VCCB, or GND = ±100 mA ]
So can we drive a MOSFET or light up up a few LEDs directly from the output of level shifter?
Would this cause any damage to the ESP32 board?
Would there be better protection to the board if all the outputs are routed through voltage shifters (something like TXS0104 for more pins) ?

And one more doubt, what happens when a pin ( configured as output ) gets shorted with ground? Like connecting a limit switch wrongly a to pin which is mapped for Spindle output.

Hello,

I try these drivers with GRBL on Arduino UNO and all four drivers can spin motor but when I try with ESP32 only two drivers TB6560 and Black driver can spin motor.

Best Regards,

TB6560

BLACK Driver

can th4e pwn be used with a laser on the K40?

Hello,

Great job 👍
As far as I know, TXS0101DBVR is new component since the 3rd version,
& I couldn't find it in the market in my region.
What does this "Voltage Level Translator" actually do in this version?
Is there any other component to replace with TXS0101DBVR ?
Any Chinese or something cheap ?

Ehsan,

I cannot experiment on this card, because I'm waiting delivery and it seems it's stuck in USA (from may 26).
I understand Covid19 emergency, but customer care appears lower than standard..
No one seems to be caring about my questions.
For bdring: feel free to erase this issue I raised
