Power module boost and step-down test board with data line

A simple multi-channel power supply board that supports typec 5v and 7-12v dc input, supports multiple 3.3v, 5v, and adjustable boost outputs.

Recently, I mainly use the esp series. 3.3v is often not enough. It is troublesome to use a breadboard and it is often easy to plug it in by mistake. In addition, there are too many dusty components on hand, so I came up with this power board.

The functions supported by this board include

1. The input has 2 5V typec ports and 1 7-12V dc port.

2. The output supports up to 10 channels of 3.3V voltage (8 channels of pins, 2 channels of terminal blocks)

3. The output supports up to 15 channels of 5v voltage (9 channels of pins, 2 channels of terminal blocks, 4 channels of USB port)

4. The output supports up to 11 channels of adjustable boost (5v boost through the sx1308 small board) (8 pins + 1 sx1308 pin + 2 terminal blocks)

5. The output supports up to 8 channels of DC port voltage (8 channels of pins)

6. With self-restoring fuse 6v/3A for circuit protection

7. Equipped with 2-channel data line test terminals, which can test data D+ and D- (1-channel USB and 1-channel pin, cannot be parallel)

8. It can also be used as a mobile phone charging extender in daily life, or as a 1-way USB hub (1-way USB with data, 3-way USB only for power supply).
