NXP Semiconductors BRKT-STBC-AGM01

Overview

BRKT-STBC-AGM01 from NXP (formerly Freescale) is a 9-axis sensor toolbox breakout board supporting sensor fusion with the FXAS21002C gyroscope and FXOS8700C 6-axis e-compass IC. It provides through-hole pin access to all critical signals including I²C/SPI interfaces, interrupt lines, reset, and power rails for both sensors, and features 18 test points for debug and validation.

For engineers reviewing the BRKT-STBC-AGM01 datasheet, BRKT-STBC-AGM01 pinout, BRKT-STBC-AGM01 application, or BRKT-STBC-AGM01 equivalent, this board enables rapid prototyping of 9-axis motion sensing systems requiring synchronized accelerometer, magnetometer, and gyroscope data acquisition with configurable I²C/SPI host connectivity and hardware interrupt support.

Technical Context

The BRKT-STBC-AGM01 integrates two discrete sensor ICs: FXAS21002C (24-pin QFN, ±2000 dps full-scale gyroscope) and FXOS8700C (16-pin QFN, ±2g/±4g/±8g accelerometer + ±1200 µT magnetometer). Both devices share common VDDIO (1.71–3.6 V) and support I²C (up to 400 kHz) and SPI (up to 10 MHz) communication protocols.

Board-level signal routing separates SA0/SA1 address pins for I²C bus arbitration, provides dedicated INT1/INT2 outputs per sensor, and includes RST lines with pull-up resistors. All sensor power domains (VDD_8700, VDD_21002, VDDIO_8700, VDDIO_21002) are accessible via test points and through-hole headers.

FAQ

What is the BRKT-STBC-AGM01 used for?

The BRKT-STBC-AGM01 is a hardware evaluation platform enabling rapid integration and testing of 9-axis motion sensing using the FXAS21002C gyroscope and FXOS8700C 6-axis e-compass. It provides direct access to all sensor interfaces, power domains, and control signals, allowing engineers to validate sensor fusion algorithms, calibrate multi-axis data streams, and prototype host firmware without custom PCB design. The BRKT-STBC-AGM01 supports both I²C and SPI host connections and includes 18 test points for signal monitoring.

Does the BRKT-STBC-AGM01 include an onboard microcontroller?

No, the BRKT-STBC-AGM01 does not include an onboard microcontroller or processing unit. It is a passive breakout board that exposes sensor pins, power rails, interrupts, and reset lines to through-hole headers and test points. Host system control - including I²C/SPI communication, data readout, and sensor configuration - must be implemented externally using a separate MCU or development board. The BRKT-STBC-AGM01 serves solely as an interface and signal-access platform for the FXAS21002C and FXOS8700C sensors.

Which sensors are supported on the BRKT-STBC-AGM01?

The BRKT-STBC-AGM01 is specifically designed for two NXP sensors: the FXAS21002C 3-axis digital angular rate gyroscope and the FXOS8700C 6-axis integrated linear accelerometer and magnetometer. These devices are pre-mounted on the board in their respective QFN packages (24-pin and 16-pin), with all signal paths routed to accessible headers and test points. The BRKT-STBC-AGM01 does not support other sensor models or third-party ICs without hardware modification.

Can the BRKT-STBC-AGM01 operate with both I²C and SPI simultaneously?

No - the BRKT-STBC-AGM01 routes I²C and SPI signals separately but does not enable simultaneous protocol use on the same sensor. Each sensor (FXAS21002C and FXOS8700C) supports either I²C or SPI operation, selected via hardware configuration (e.g., SPI_CSB_21002 pin state). The BRKT-STBC-AGM01 provides dedicated SCL/SDA and SPI_CSB/MISO/MOSI/SCLK pins, but concurrent dual-interface operation per sensor is not electrically supported. The BRKT-STBC-AGM01 allows flexible host interface selection per sensor, not concurrent use.

Are the pin assignments on the BRKT-STBC-AGM01 documented in a schematic?

Yes - the BRKT-STBC-AGM01 pin assignments are fully documented in the official Quick Reference Card (Rev C, Doc ID 920-75782) and associated Sensor Toolbox reference materials. Header pinouts map directly to sensor signals such as INT1_21002 (Pin 8), RST_21002 (Pin 7), SCL1 (Pin 4), and VDDIO_8700 (Pin 3). Test point labels (e.g., VDD_8700, SA0_8700) match internal net names. The BRKT-STBC-AGM01 schematic is available from NXP's Sensor Toolbox resource portal under design files.
