Hello.
I need to connect 100+ Steppers to Teensy, but I need only working as a time.
By the way i'm thinking in the following connection.
1) Teensy 3.2 (model that i own several units)
2) DRV8825 or EasyDriver or (need to test) as Driver
3) MCP23017 16 bit i2c IO Expander
4) Steppers Bipolar Nema size ...
I'm planning to wire all to the driver and with the MCP23017 activate 4 transistors for each channel for drive the steppers input to the driver output.
Any can think in better design?.
Design need individual steppers is not possible to use less.
Thanks.
