Description
Red light power, green light hub.
The extended version can act as a back cover.
Reserve 4 m3 holes for easy mounting brackets.
Divided into two plates, you know (≤10cm)
The red arrow is the selection switch of flashing and hub,When you connect to the lower computer, you can dial it to the hub (at this time, the hollow will be lit),When you flash the machine, you will dial it to the flashing machine (even Xiaozheng K6 motherboard also needs to be dialed to the flashing machine,Because Xiaozheng k6 motherboard integrates hub,At this time, you only need to use a data cable to connect the extended version of the "Xiaozheng k6" USB-A and the typec port of the Xiaozheng k6 motherboard)
The components are tested internally, which is beautiful and can avoid static electricity or foreign body contact and short circuit.
The components in the red box can not be pasted (so that there is no wide voltage input function, and only typec5v power supply) The green arrow is the contact point of the mobile phone.
If a WiFi antenna is added to the cover, the signal will be improved compared to directly removing the back cover (the original antenna on the back cover).
No fancy circuits, multiple incense burners and multiple ghosts, everything is simple and convenient DIY. The circuit has been extensively verified (the one with the most sales of the direct power supply extended version of the Redmi 2 is this circuit)
