1 

5V_AREF 

5V analog reference as used by the internal DAC. Max. load 0.5mA 

2 

AIN0 / VIN 

Analog input: Used for velocity control in stand alone operation by 
supplying external 0 - 10V signal 

3 

AIN1 

Additional analog input. Currently unused – leave open 

5 

DIRIN 

5V TTL input. Tie to GND to inverse motor direction, leave open or 
tie to 5V otherwise. 

6 

GPIO1 

Starting from Version 1.02: This pin outputs a tacho impulse, i.e. 
toggles on each hall sensor change 

7 

/MOTOR_OFF 

Emergency stop. Tie this pin to GND to stop the motor (same as 
Motor Off switch on PCB). The motor can be restarted via the 
interface, or by cycling the power supply. 

8 

LED_TEMP 

5V TTL output: Toggling with 3Hz when temperature pre-warning 
threshold is exceeded, high when module shut down due to 
overtemperature. 

9 

LED_CURLIM 

High, when module goes into current limiting mode 

10, 14 

+5V 

5V supply as reference for external purpose 

11, 12, 26 

GND 

GND reference 

20 

RXD / 
RS485INV 

RXD signal of module for RS232 communication (RS232 version) 
Inverting RS485 signal (RS485 version) 

22 

TXD / 
RS485NI 

TXD signal of module for RS232 communication (RS232 version)  
Non-inverting RS485 signal (RS485 version) 

All other pins   

Leave all other pins unconnected!
