This module is a multi-input, multi-output power supply voltage regulator module. The module can meet needs of multiple loads with same power supply, and onboard power indicator indicates whether power is turned on. 3-way input interface, 7-way output interface, each output interface has 3 identical outputs, which is convenient for connection during experiments. In order to stable output, it is necessary to maintain a voltage difference of more than 1.5V Multiple input: Pad/Type-C/DC socket (compatible with DC5.5 * 2.1/2.5 female heads) Attention: The input voltage must be at least 1.5V higher than output voltage<br><br>Pin description: VIN input positive pole Type-C/DC socket input VIN/1.2/1.5/1.8/2.5/3.3/5 output positive pole G input/output negative pole Note: The output VIN can also be used as input Color: Black Material: PCB+components<br><br>Package Contents: 1 * Power Voltage Regulator Module<br><br>Only above package content, other products are not included. Note: Light reflection and different displays may cause color of item in picture a little different from real thing. The measurement allowed error is +/- 1-3cm.
