The G201X is designed to run a large stepper motor efficiently and inexpensively. This is made possible due to its CPLD design, which moves most formerly analog operations to firmware while still maintaining its large dual H-bridge power section. It’s oversized MOSFETs can run a stepper motor up to 7A and 80VDC without issue, pushing its motor range to NEMA 17 through 42.
Pinout
The G201X uses a 2-piece modular main connector. The connector is split in two pieces; terminals 1 through 6 (power supply and motor leads) and terminals 7 through 12 (control interface). Each can be removed separately by pulling the connector body upwards and off of the mating header pins on the G201X. The connectors must initially be removed to mount the G201X to a heatsink or chassis.
| Pin | Name | Description |
|---|---|---|
| 1 | Power Ground | Connect the negative (black) lead of your power supply to this terminal. |
| 2 | Power (+) | Connect the positive (red) lead of your power supply to this terminal. It must be between +18VDC to +80VDC. |
| 3 | Motor Phase A | Connect one end of your “Phase A” motor winding here. |
| 4 | Motor Phase Ā | Connect the other end of your “Phase A” motor winding here. |
| 5 | Motor Phase B | Connect one end of your “Phase B” motor winding here. |
| 6 | Motor Phase B̄ | Connect the other end of your “Phase B” motor winding here. |
| 7 | Disable | This ! will force the winding currents to zero when shorted to ! 12. |
| 8 | Direction | Connect the DIRECTION signal to this terminal. |
| 9 | Step | Connect the STEP signal to this terminal. |
| 10 | Common | Connect the controller’s +3.3VDC, +5VDC or GND to this terminal. |
| 11 | Current Set | Connect one end of your current set resistor to this terminal. |
| 12 | Current Set | Connect the other end of your current set resistor to this terminal. |
