This is to include the modification done for the WIZnet contest.
The design team Olivier Gaillard and Vasilis Vorrias converted the original M10CUBE PICO CNC design to accommodate WIZnet Pico clone instead of Raspberry Pico and make WIZcube CNC we may say.
WIZcube CNC is in heavy development and soon a prototype will be in out hands

This is an EXPERIMENTAL module code named M10NC02-10 designed with KiCAD6. Will be using GRBLHAL software https://github.com/grblHAL
On board Raspberry Pico.
All modules from version 10 and later are sharing the new 90x90mm PC
Note the bright green 2X8 Pin Socket connector to directly connect one I/O M10CUBE module directly from optocouplers with the CPU . That way critical signals will go directly to CPU and not via I2C or SPI.
I/O modules have a Pin Header (in place of indicating LED) for interconnection between the two
One interesting feature we want to have on this design is to use the same module as a CNC Remote.
RS485 chip is on board for wired connection between modules and a UEXT (OLIMEX) connector carrying I2C, SPI, UART signals for mounting various add-ons on the remote module like Display, Rotary Knobs e.t.c.
Thea idea using an ESP-01 WiFi or a Bluetooth module for wireless communication is on the table.
