DC_5V/3V3_TWO Channel

Overview

This module uses 4 LDOs as the main chip to realize voltage reduction from 6V to 12V. The output voltages are: VCC, 5V, 3V3. There are 17 groups of 5V and 3V3 in total. If it is not enough, you can also use the expansion port to add output ports.
This module integrates an anti-reverse connection circuit to prevent the user from connecting the input power reversely and damaging the module.

PCB update note
P2: The height of pin 1 is changed to 2.2mm, and the height of pin 2 is changed to 2.2mm.

Power line width precautions:
35um: 1.5mm- 3.2A current 2mm-4A current
50um: 1.5mm-3.5A current 2mm-4.3A current
70um: 1.5mm-4.2A current 2mm-5.1A current
So: the total power line width should be 2mm

PCB attention:
1. Two-way Do not short-circuit the ground directly, connect them all to the input ground.
2. The power line must meet the 6A requirement. 3.
The 470uF electrolytic capacitor should be the current outlet
. 4. All pads of P4 (4*4*4Pin) should be changed to 1.3mm.
5. U3 and U4. The internal connecting pins of the chip are not connected to the PCB
