Shunt Regulator: 26.4V, 2.80Ohm, 15W hub-module Power-save mode with ultrasonic operation

Power-save mode with ultrasonic operation that increases light load efficiency by reducing switching frequency

3 V analog voltage interface for direct connection to potentiometers and analog joysticks

we recommend careful reading of the A4990 datasheet (301k pdf)

the most significant of which is the enhanced power system that allows an expanded operating range of 6

so you do not have to program this sequence of steps yourself

Shunt Regulator: 26.4V, 2.80Ohm, 15W hub-module Power-save mode with ultrasonic operationThis shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a fixed set point of 26. 4 V, a shunt resistance of 2. 80 ohms, and a total of 32 SMT shunt resistors populated on both sides of the PCB (this is the higher power version). An external potentiometer can also be added to change the set voltage. Specifications: Output voltage: 26. 4 V Shunt resistance: 2,8 Ohm Power:
