What should engineers review before using VC-02-Kit_EN?

Provide a 5 V supply capable of more than 500 mA, verify UART wiring and firmware-update method, and select either the 3.3 V I2C interface or the 5 V I2C interface. The two I2C voltage-level interfaces cannot operate simultaneously.

What is the pinout of VC-02-Kit_EN?

Use the VC-02-Kit_EN datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about VC-02-Kit_EN pinout to locate pins, power rails, and interface signals before layout.

Best for

VC-02 offline voice-control prototypes
Voice-controlled home appliances
Chinese or English local voice-command evaluation

Avoid if

A documented production compliance status is required
A compact production module rather than a development board is needed
The design requires simultaneous 3.3 V and 5 V I2C buses on this board

Check before use

5 V supply capability above 500 mA
UART1 TX1/RX1 connection and logic-level compatibility
Firmware image type for JTAG or serial update
I2C voltage-level interface selection
