Product description: Pololu Simple High-Power 18v15 - USB motor driver 30 V / 15 A
| The manufacturer provides a detaileduser guide. |
Main features
- Easy-to-use bidirectional DC motor controller
- Power supply: 5.5 V to 30 V (18v7, 18v15, 18v25 versions) and up to 40 V (24v12, 24v23)
- From 7A to 25A continuous current depending on the version
- Four communication protocols:
- USB - direct connection to a computer
- TTL - serial interface for connection with e.g. a microcontroller
- Radio signal (RC)
- Analog input (0 - 3.3 V) - connection of a potentiometer or joysticks
- Simple configuration via USB (Windows 7, Vista, XP, Linux)
- Detailed information is available in theinstruction manual
| For systems using a 24 V supply voltage, we recommend the use of a24v12or24v23 driver. When using18v17,18v15and18v25controllers, there is a risk that the voltage at some moments will exceed the permissible value of 24 V (e.g. when the batteries are fully charged), which may cause permanent damage to the system. |
Additives:
- Manualcontaining sample connections and source codes
- Adjustable start and maximum speed
- Option to prevent accidental starting of the engine
- Adjustable PWM frequency from 1 kHz to 22 kHz
- Can be turned off when the supply voltage is too low
- LED diode indicating the appearance of errors
