『Anxinke Bluetooth Development Board PB-02-Kit』-0: First Impression [Copy link]

The "Anxinke Bluetooth Development Board PB-02-Kit" is the most neatly made domestic board I have received this year. The component layout is quite standard, allowing users to see at a glance:

One thing that was confusing was that there was no response after plugging in the power, so I thought I had to post another help thread, but after reading this thread , I understood: According to the board description:

“

PB-02-Kit Bluetooth development board is a smart lighting development board developed based on the PB-01 module of Anxinke. PB-02-Kit comes with onboard antenna, RGB lamp beads and cold and warm lamp beads, which can be adjusted by developers.

PB-02-Kit supports BLE Mesh networking, AT commands, SDK secondary development, Tmall Genie voice direct control, Android/IOS APP control, and WeChat applet control.

”

Note the "intelligent lighting", "built-in RGB lamp beads and cold and warm lamp beads" and "support Tmall Genie direct voice control" mentioned here. It seems that the manufacturer did not include a power indicator light intentionally, and the purpose may be to highlight the built-in lamp beads and voice control functions.

There is another thing to note. Judging from the information provided by the board, the lead pin arrangement is "N" type, rather than the common "U" type. This may be related to the regular layout mentioned at the beginning of this post.

There don't seem to be many cases where the pins are arranged in "N" type. What does this have to do with the manufacturer's layout?

I want to see how voice control is achieved and what methods can be used to turn on the lights.

This is my understanding based on my own experience in soldering and routing. It seems that PB-02-Kit uses a double-layer board. Since the pin distribution of the chip itself is fixed, it is possible that the pins of the test board are arranged in this way to have fewer cross-routing.

Yes, the PB-02 development board is a double-layer board.
