Thanks for the replies.
I decide to sell my relay board locally and make a new one by myself.
I have searched internet and find two options. I think they will both work
with beaglebone black.
Please tell me: Will they work or not?

These transistors, they are active low. We can only sink and drive 6mA. You
could try adding a pullups to each signal to pull the voltage higher, Tie
then to 3.3V.

My relay module is must be something like this.
Relays are 5v, so i use VDD_5V(P9_05) to drive them. GPIO turns on and off
them in normal. But there is a problem in my situation. I'm trying to find
it.

I can't tell much from a picture. Doe sit have a schematic, or a link to
one?
If the relays are 5V, then you cannot drive them from a GPIO as it is 3.3V
and delivers only about 6mA.. Connecting 5V will blow the processor.
You would need a level shifter such as a transistor to drive the relay..
Hello,
I'm trying to use relay module with beaglebone black.
I bought relay module from china.
It is very similar to this:

I have connected VCC to BBB's VDD_5V(P9_05) and GND to BBB's DGNG(P9_01).
Here is the pro
