DESCRIPTION 
2 
MOSFET Driver Error 
This happens when there is undervoltage error or hardware failure. 
Please contact support@cytron.io for more details. 
3 
Overvoltage Error 
Power input voltage has exceeded the maximum rating. If switching 
power supply is being used, connect a motor shunt regulator or 
rechargeable battery with same voltage in parallel with the power 
supply. This is to absorb the regenerative energy from the motor during 
deceleration. 
4 
Overheat Error 
Board temperature is over 80℃ (176℉). This is just served as a warning. 
The motor driver can still be safely operated.
