How to start
Quick Start Guide
1. Wide operating input voltage range 6.5…32V (32V is the absolute maximum).
2. Each output can control independent voltage sources in the range of 1…32V.
3. High output frequencies:
Without heat sinks: at full load 0…2kHz, fully covering Arduino board’s default PWM speed.
With additional heat sinks on transistors: 4…25kHz at full power. 25…100kHz with smaller currents.
4. Dozens of protections for beginners and professionals:
● FlashBack ® (FlyBack) protection ● Five-level overcurrent protection! ● Overtemperature protection
● Power input polarity protection ● Too low logic +5V supply warning & protection ● Logic input & analogue output ESD protection
● Logic circuit overvoltage protection (TVS & PPTC) ● Logic circuit overcurrent protection with 0.5A PPTC
5. Three FeedBack outputs to Arduino’s analogue (user selectable) inputs. Current measure expression 1V/10A.
6. Four coloured status LED indicators on the PCB.
7. Input/output logic levels are universal 5.0/3.3/2.5V and work with many boards.
8. Integrated high efficiency step-down DC/DC converter 0.5A to supply Arduino +5V pins and the module itself.
9. Pins compatible with most popular Arduino boards (including NANO, UNO, and MEGA).
10. High quality components and power connectors with spring-cage technology (

11. Maximum continuous total output power up to 800W. Maximum output power when stacked up to 1.5kW.
12. Operating ambient temperature: -20…+50° degrees Celsius.
