JC DFU Box C2 Teardown

Spread the love

I recently purchased the JC DFU box c2 as a handy DCSD cable and restore mode dongle.

First thing I did was tear it down so we can see whats inside!

Here is the main board, the box is driven by a STM32 micro controller and even has a program header .

There is also a FE1.1S USB 2.0 HIGH SPEED 4-PORT HUB CONTROLLER

Some current management ic (can’t work out chip number), probably for the current measurement feature (tops out around 1amp).

Two crystals, one for the main microcontroller (8Mhz?) and one for the USB hub (12MHz)

The lightning port is on a sub PCB, probably for easier product adaption in the future (USB-C maybe?)

Finally we have the display, just a simple OLED screen, nothing special
