NXP Semiconductors FRDM-STBC-AGM02

Overview

FRDM-STBC-AGM02 from NXP Semiconductors is a Freedom-compatible sensor board designed to enable full 9-axis sensor fusion (accelerometer + gyroscope + magnetometer) on Kinetis MCU development platforms. It integrates the FXOS8700CQ 6-axis accelerometer/magnetometer and FXAS21002 3-axis gyroscope, supports I2C interface at standard addresses (0x1E, 0x20), and is compatible with FRDM-K22F, FRDM-K64F, FRDM-KL25Z, and other NXP Freedom base boards.

For engineers reviewing the FRDM-STBC-AGM02 datasheet, FRDM-STBC-AGM02 pinout, FRDM-STBC-AGM02 application, or FRDM-STBC-AGM02 equivalent, this board serves as a validated hardware foundation for developing orientation-aware embedded systems including AHRS, eCompass, motion-controlled UIs, and inertial navigation prototypes using the NXP Sensor Fusion Library v7.00.

Technical Context

The FRDM-STBC-AGM02 implements a modular sensor interface architecture that connects via standard 10-pin Arduino-compatible headers to Freedom base boards. It routes all sensor signals-including I2C SDA/SCL, interrupt lines, and power-through configurable jumpers (J6/J7) to support multiple I2C master sources and avoid bus conflicts.

It delivers raw 3-axis acceleration (±2g/±4g/±8g ranges), 3-axis angular rate (±250°/s to ±2000°/s), and 3-axis magnetic field data (±1200 µT) with factory-trimmed calibration coefficients accessible via register reads. The board includes onboard voltage regulation (3.3 V) and level-shifting circuitry to ensure compatibility across 3.3 V and 5 V host platforms.

FAQ

What is the primary function of the FRDM-STBC-AGM02?

The FRDM-STBC-AGM02 is a sensor expansion board that provides synchronized 9-axis motion sensing (accelerometer, gyroscope, and magnetometer) for NXP Freedom development platforms. It enables real-time orientation computation using the NXP Sensor Fusion Library v7.00, supporting algorithms such as tilt-compensated eCompass, gaming-grade rotation tracking, and full 9-axis AHRS. The FRDM-STBC-AGM02 is not a standalone computing device but a hardware enabler for sensor fusion firmware development.

Which base boards is the FRDM-STBC-AGM02 compatible with?

The FRDM-STBC-AGM02 is mechanically and electrically compatible with all NXP Freedom development boards featuring Arduino R3–compatible headers, including FRDM-K22F, FRDM-K64F, FRDM-KL25Z, FRDM-KL26Z, FRDM-KL46Z, and FRDM-KV31F. Its jumper-selectable I2C routing (via J6/J7) ensures reliable communication even when multiple I2C peripherals share the same bus on the base board. The FRDM-STBC-AGM02 does not require modifications to base board firmware or hardware layout.

Does the FRDM-STBC-AGM02 include Bluetooth or wireless connectivity?

No, the FRDM-STBC-AGM02 does not include Bluetooth, UART-to-USB bridges, or any wireless transceivers. It is a pure sensor interface board focused on delivering calibrated, time-aligned motion data to the host MCU. For wireless telemetry or GUI interaction, users must pair the FRDM-STBC-AGM02 with a base board that includes Bluetooth (e.g., FRDM-FXS-MULT2-B) or add an external module. The FRDM-STBC-AGM02 communicates exclusively via I2C and supports only wired sensor data acquisition.

How does the FRDM-STBC-AGM02 differ from the FRDM-STBC-AGM01?

The FRDM-STBC-AGM02 is functionally identical to the FRDM-STBC-AGM01 in sensor complement (FXOS8700CQ + FXAS21002), pinout, jumper configuration, and firmware compatibility. Both boards implement the same 9-axis sensor architecture and are referenced interchangeably in NXP documentation as successors to the deprecated FRDM-FXS-9-AXIS. No electrical, mechanical, or functional distinction between FRDM-STBC-AGM01 and FRDM-STBC-AGM02 is documented by NXP; they represent successive production batches of the same design.

Can the FRDM-STBC-AGM02 be used with non-NXP microcontrollers?

Yes - the FRDM-STBC-AGM02 is electrically agnostic and can interface with any 3.3 V microcontroller supporting standard-mode or fast-mode I2C (100 kHz / 400 kHz). Its sensors expose standard register maps and require no proprietary drivers. While NXP's Sensor Fusion Library v7.00 targets Kinetis MCUs, the raw sensor data from the FRDM-STBC-AGM02 is fully accessible to STM32, ESP32, or other ARM Cortex-M platforms via generic I2C read/write operations. The FRDM-STBC-AGM02 requires no NXP-specific silicon to operate.
