HDMI FPC flexible cable extension cable adapter

Overview

The line sequence uses the existing HDMI adapter line sequence on Taobao, the signal will be better, but because the drawing board capability is not enough, it is recommended that the fpc cable is as short as possible. I have only tested the 30cm fpc cable, and there is no longer one. test.

Micro usb patch contact flying lead board

Introduction: Suitable for removing the micro usb female socket and replacing it with contacts that are easier to solder with flying wires. Inspired by @mz8023yz https://oshwhub.com/mz8023yt/Micro-USB-2-Type-C

The thickness of the board is 0.8mm. Because it is too small, I just "pieced it together" and just cut it by myself after the big board came out.
I didn't bring out the ID pin, mainly because I didn't need it and was just being lazy.

Verified USB HUB is based on SL2.1A one to four

Introduction: Based on SL2.1A USB2.0HUB, TYPE C input, four standard USB A female outputs, simple peripherals, only four capacitors and one crystal oscillator

# Based on the SL2.1A USB2.0 HUB

diode, you do not need to directly remove it, and then short-circuit or modify the PCB so that the power is directly input to the chip. SL2.1 has built-in LDO, and the surrounding capacitors are mainly used to filter the power supply and built-in LDO.

Power distribution

Introduction: pac/pdc dual power supply redundant backplane. The connector is limited to 28p + 20s, and is sold on Alibaba for 22 yuan (it actually uses a PCIE slot as the backplane of the pac3000s12, so it is not afraid of melting and sparking)

The base plate is suitable for the 2.5-inch hard drive bay of Lianli O11DMINI. Copper studs and copper screws are used to connect the upper and lower layers. The base plate needs to be welded with a 1MM thick copper strip. Please cut it by yourself.
