The output

5V, 3.2A Step-Down Voltage Regulator D36V28F5 hub-sensoren but it can be foundThis small synchronous switching step down regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V. The board measures only 17. 8mm 20. 3mm yet delivers typical maximum continuous output currents between 2. 5 A and 4 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low power state with a current
