An excellent board , that's now being used full time.
For Grbl_ESP32 CNC Development Board V4.1
An excellent board for prototyping , that has made it as a permanent resident for my DIY CNC Router.
I bought this board as I was keen to tryout an alternative hardware platform to the mega, as I felt I was reaching the "speed limit" of the Mega2560.
Having purchased an ESP32 , which isn't very breadboard friendly, I was pleased to find this board , It even came with PCB standoffs which is a good idea to prevent shorts. I quickly cobbled up some fairly long leads to run my CNC Router to try it out , I've also added a RS485 link to control VFD Spindle and It seems to work very well.( it took a little time to add the software to control the VFD )
The patch leads were shortened and It is now resident at the heart of my CNC router.
The board has been well thought out , it contains additional pads, which I ended up using as my ESP32 board was 0.1" wider than the vendor's.
Its nice that all of the pins have an associated ground with them , making it easier to connect up. I've also asked for a power supply for each of the limit switch pins, as I use opto switches for these, though it was quite easy to add.
I'm also using off board stepper drivers , but these were quite easy to connect to with a few pin headers.
Many thanks for an excellent product and great support.
