Driver Connection and PiBot Box Use
The second generation of PiBot Box will put forward which can include 6 motor driver and the Manual Controller.
Settings of Driver
PiBot TB6600 Stepper Driver all input pins build-in connect to GND with a 100KΩ resistance.
| M1(input) | M2(input) | M3(input) | Mode (Excitation) | Illustrate |
| L | L | L | standby mode (operation of the internal circuit is almost turned off) | H-High voltage, L-Low voltage |
| L | L | H | 1/1(2-phase excitation, full-step) | |
| L | H | L | 1/2A type (1-2phase excitation A type) (0%-71%-100%) | |
| L | H | H | 1/2B type (1-2phase excitation B type) (0%-100%) | |
| H | L | L | 1/4 (W1-2phase excitation) | |
| H | L | H | 1/8 (2W1-2phase excitation) | |
| H | H | L | 1/16 (4W1-2phase excitation) | |
| H | H | H | standby mode (operation of the internal circuit is almost turned off) |
| Auto\Latch(input) | Effect | Illustrate |
| L | TSD and ISD functions return by either of turning on power supply again or
programming the ENABLE as H → L → H || default set to High | |
| H | TSD and ISD functions return automatically |
| TQ(input) | Vref Voltage Ratio | Effect | Illustrate |
| L | 30% of the input Vref | decrease 70% Motor current | default set to High |
| H | 100% of the input Vref | full current,more power |
100% Current Settings (Current value)
100% current value is determined by Vref inputted from external part and the external resistance for detecting output current. Vref is doubled 1/3 inside IC. Per the [TB6600 datasheet], the calculation for current is:
Io(100%) = (1/3 × Vref) ÷ RNF
The average current is lower than the calculated value because this IC has the method of peak current detection.
RNF should be 0.68||0.68||0.68=0.2267Ω
Sometimes this value can be set by experiment, that Stepper motor not heating, small noise and the chip do not get too hot.
How to Build
Not Open Source?
While the following files give an idea how the schematics looks, it isn't editable. Also, the Layout has both sides laid on top of each other, so it's impossible to etch/make a copy. Both are reasons to consider this stepper driver to be not Open Source. To resolve this, please add original design files of both. Thank you.

- Solder Images
- Prepare all of the components to build a PiBot TB6600 Stepper Driver;
- You'll need a soldering toolkit and SMT soldering toolkit to finish this board.
- Use SMT soldering toolkit
- Apply solder paste to every exposed SMD pad.
- Place each SMD component on its appropriate pad.
- Place populated board on a cold hotplate,turn hotplate on,board solders itself!
- Solder in remaining through hole components.
- If you without a soldering toolkit, you can also use an tweezers and an soldering iron finish them by manual.
- Use soldering toolkit
- Insert through hole components.
- solder all these pins to the pad.
- Solder the TB6600 in bottom
- Be careful, please ensure no short cut and insufficient solder.
- Test
- Before plug in the power source, you first need to check the polarity of electrolytic capacitor, chip and diode.
- Use an digital multimeter to test the resistance value of the power. Usually, it has a increase resister. Ensure no short cut and insufficient solder.
- Now, you can plug in the power source, the power LED (red) lighten. Usually,the Run LED(green or red) lighten(it not related).
- Connect the control pins and output pins(A1-Red A2-Green B1-Yellow B2-Blue or A1-Black A2-Green B1-Red B2-Blue), input signal,

Developments
- PiBox has been put forward. It is made of steel plate, which can contain 1 to 6 drivers and with a good heat sink effection.
- You can change the connection of the 74HC123D's output pin to the TQ pin(the 3rd pin of TB6600 chip).
- The new driver design will use the single pin header out going the setting table, so that you can program to them.
