Hello, I currently use Arduino Nano's loaded with GRBL to control CNC machines. I use the Arduino Nano GRBL shield v4, it works on 5 volts.
I want to use STM32 blue pills in its place. I already have the GRBL code for the STM32 blue pills. I require a Schematic and PCB design, basically a pinout conversion board, using the components in the pictures in the file section. I also would like Bluetooth added using the HC-06 module. Many of the Stm32 blue pill i/o pins, are not 5 volt tolerant, 12 to be exact. Please use 3, 4 channel logic converter modules shown in picture to correct this in your design. Basically a pinout conversion board. Some of the STM32 pins are not used. I am looking to convert the footprint of the STM32 blue pill to the footprint of a Arduino Nano. Please read everything well, and look at the pictures especially the first 2. They show the different GRBL pinouts of both controllers. You may ask why I want to do this? It is faster and the software responds much smoother.
If you think you can complete this project with minimal questions, please bid. Please bid your actual cost. All others will not be considered. Thank You.
Forgot to mention I want the designs in KiCad.
