Reliable for industrial prototyping
We ordered ten of these for a prototype batch. All units performed consistently within spec. The SPI interface speed is impressive.

Good sensitivity
Great sensor for my DIY drone project. The data is smooth and accurate. Only giving 4 stars because the soldering pads are a bit small for beginners.

Perfect drop-in replacement
Worked flawlessly as a replacement for my old ADXL345 module. The pinout is identical, and the I2C communication was stable right out of the box.

Works but documentation could be better
The hardware works fine, but the included datasheet link was broken. Had to search online for the register map. Once figured out, it works well.

Great value
Very affordable compared to other accelerometer modules. It handles vibration detection perfectly for my alarm system project.

Easy to integrate
Found plenty of libraries compatible with this chip. Setup took less than 10 minutes with my Arduino Uno. Highly recommended for students.
Q: What is the default I2C address for this sensor?
A: The default I2C address is 0x53 when the CS pin is pulled high. If CS is pulled low, it switches to SPI mode.
Q: Is this module compatible with 5V logic levels?
A: Yes, the GY-346 module includes an onboard voltage regulator and level shifter, making it safe to use with both 3.3V and 5V microcontrollers.
Q: Does the package include header pins?
A: No, the module is shipped without header pins to allow for flexible mounting options. You will need to solder your own headers or wires.
Q: Is there a sleep mode to save power?
A: Yes, the sensor features an automatic sleep mode when no motion is detected, significantly reducing current consumption to microamp levels.
Q: Can this measure vibration frequencies above 100Hz?
A: Yes, the ADXL346 has a bandwidth that can be adjusted up to 1600Hz, which is sufficient for most vibration monitoring applications.
