Solid build quality
The PCB looks well-made with clear labeling for pins. Only giving 4 stars because the included header pins were slightly bent upon arrival, but easily straightened.

Compact and reliable
Small form factor makes it easy to integrate into tight spaces. I used it for a self-balancing robot prototype, and it performed consistently over several hours of testing.

Exceeded expectations
Very responsive to movement changes. The ability to switch between different g-ranges via software is a huge plus for versatile applications.

Good accuracy, slight noise
The tilt angle readings are quite accurate after calibration. I noticed a little bit of noise in the raw data, but a simple moving average filter fixed it right up.

Great for learning embedded systems
Bought this for my university project on motion sensing. The documentation online is plentiful, and the SPI mode offers faster data retrieval when needed.
Q: Does this module come with header pins soldered?
A: No, the module is shipped without header pins soldered to allow for flexible mounting options. You will need to solder them yourself if required.
Q: Does it support interrupt outputs for freefall detection?
A: Yes, the ADXL345 chip supports programmable interrupts for events like freefall, activity, and inactivity. These are accessible via the INT1 and INT2 pins on the module.
Q: Is there a built-in regulator on the board?
A: Yes, the GY-291 module includes an onboard voltage regulator, allowing you to safely power it with anywhere from 3.3V to 5V.
Q: What is the default I2C address?
A: The default I2C address for the ADXL345 on this module is usually 0x53. However, some variations allow changing this via the CS pin configuration.
Q: Can I use this directly with a 5V Raspberry Pi GPIO?
A: While the module supports 5V input voltage, the logic level for I2C/SPI is typically 3.3V. We recommend using a logic level converter when connecting to a 5V system to ensure safe communication.
