Mingjiada Supply/Recycle ADI ADXL377 Low Power 3-Axis MEMS Accelerometer, For UAV Sensor Applications

Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing provider of supply and buy-back services for the ADI ADXL377, the ADI ADXL377BCPZ three-axis ±200g analogue MEMS accelerometer, suitable for drone crash recording, collision detection, hard landing and high-impact testing. Mingjiada serves end-user factories, R&D teams, distributors and stockists, offering genuine off-the-shelf stock, BOM fulfilment, sample procurement and stock buy-back services.

In applications such as drones, industrial impact detection, collision recording and flight data acquisition, high-G accelerometers play a vital role in capturing transient impacts. ADI’s ADXL377 is a classic three-axis high-G analogue MEMS accelerometer, featuring a ±200g measurement range, analogue voltage output and a compact, low-power package, making it suitable for drone attitude monitoring, fall impact detection and high-speed motion data acquisition.

ADXL377 Product Overview
The ADXL377 is a three-axis analogue MEMS accelerometer developed by ADI, primarily designed for high-impact and high-G detection. Unlike common low-G inertial measurement units, the ADXL377 has a measurement range of ±200g, making it suitable for measuring transient impact events such as collisions, drops, explosions, ejection and crashes.
The ADXL377 utilises an analogue voltage output, with three-axis acceleration data output as an analogue signal, facilitating acquisition by an external ADC. Its compact LFCSP package and low power consumption make it suitable for space-constrained embedded systems. In the drone sector, the ADXL377 is more commonly used for impact monitoring, collision logging, flight data recording and crash analysis, rather than as a core sensor for flight control and attitude control.

Why is the ADXL377 of interest for drone sensor applications?
The sensor requirements for drones are highly specialised. Flight control systems typically require low-G, high-precision IMUs for attitude estimation, whilst high-G accelerometers such as the ADXL377 are better suited to the following tasks:
Crash and collision detection
When a drone crashes, collides or makes a hard landing, the ADXL377 can record high-G impact data to provide evidence for accident analysis.
Flight Data Recorder
In flight data recording systems, high-G accelerometers can be used to capture abnormal impact events, helping to pinpoint the cause of faults.
Launch and Ejection Impact Monitoring
Certain drones or aircraft generate high-G impacts during take-off, ejection or payload deployment; the ADXL377 can be used for process monitoring.
Payload and Structural Impact Testing
In structural testing of drone-mounted equipment, gimbals, battery packs and similar components, the ADXL377 can be used to evaluate impact response.
Therefore, whilst the ADXL377 is not a flight control attitude sensor, it is a vital component in the field of drone impact monitoring and safety logging.

Typical Applications of the ADXL377
Drone collision logging
Flight data recorders
Industrial shock and vibration testing
Automotive collision and safety testing
Impact detection for sports equipment, helmets and protective gear
Drop detection for consumer electronics
