[Xingkong board Python programming learning main control board] Open source - Xingkong board expansion board (conversion board) design [Copy link]

The IO interface of the Xingkong board is at a 3.3V voltage level, and some of my own modules are not the same as the module interfaces of DF, so I designed an adapter board that can connect to the Xingkong board.

You can also convert the signal on the line board, take only the signal, and supply power separately.

In addition to the micro:bit vertical socket, the expansion board also has a pice-x4 connector that can be connected to the main control board of your own design and reversely connected to the DF module.

Gold finger design is used to make it compatible with another expansion board designed by myself.

The onboard 5V-3.3V DCDC power supply has an output capacity of 2A, which is sufficient depending on the DCDC chip used.

On the front are some connectors, power supply.

On the back is a Type-C power supply interface and some connectors.

Since the sensors on the Xingkong board are already rich enough, no other interfaces are added to the expansion board.

Note: The expansion board is divided into two parts, the left part is the 3.3V power interface, and the right part is the 5V power interface. Do not connect them incorrectly to avoid burning the board.

The file is a gerber file. Since the board has just been produced and has not been verified yet, you can wait for me to verify it. After confirming that it is correct, you can produce the board.

After submitting the board, I remembered that I should add a battery-powered interface. I will add it in the next version.

This is very awesome, keep it up, and look forward to more exciting works!

Directly draw the expansion board . Like. Play well to replace the Raspberry Pi.

Awesome! It's really fast. The expansion board is already being prototyped.

The playability is very high, but the performance may not be as good as Raspberry Pi

This was planned from the beginning, and once it was finalized, it was faster to draw the board.

I thought it was a cheat code to expand the Xingkong board, but it seems they have found another way.
