NXP Semiconductors FRDM-STBC-AGM04

Overview

FRDM-STBC-AGM04 from NXP is a sensor toolbox shield development board supporting simultaneous evaluation of the MMA8652FC 3-axis accelerometer, FXAS21002C 3-axis gyroscope, and MAG3110 3-axis magnetometer via dual I²C interfaces (I2C_SCL0/I2C_SDA0 and I2C_SCL1/I2C_SDA1), designed for rapid prototyping of 9-DOF motion sensing applications on Arduino R3–compatible Freedom platforms such as FRDM-K64F.

For engineers reviewing the FRDM-STBC-AGM04 datasheet, FRDM-STBC-AGM04 pinout, FRDM-STBC-AGM04 application, or FRDM-STBC-AGM04 equivalent, this board enables hardware-validated sensor fusion testing, I²C bus arbitration verification, and cross-sensor timing alignment analysis without custom PCB design.

Technical Context

The FRDM-STBC-AGM04 implements fixed-function interconnect logic to route I²C signals from two independent buses (Bus 0 and Bus 1) to three discrete sensors: MMA8652FC on Bus 1 (IN1_8652), FXAS21002C on Bus 1 (IN1_21002) and Bus 2 (IN2_21002), and MAG3110 on Bus 1 (IN1_3110). Each sensor retains its native I²C address and operates at standard-mode (100 kHz) or fast-mode (400 kHz) speeds.

Power is supplied via VDD pins (2 mm × 2 mm DFN and 4 mm × 4 mm QFN footprints support 1.71–3.6 V operation per sensor), with dedicated GND connections (pins 7 and 6) and 14 test points for signal probing. The board provides no onboard voltage regulation or level shifting - host board must supply compatible logic levels and rail voltages.

FAQ

Does the FRDM-STBC-AGM04 require external power or drivers?

No, the FRDM-STBC-AGM04 draws power directly from the host Freedom board (e.g., FRDM-K64F) via VDD and GND pins and does not include onboard regulation. Drivers are provided by NXP's OpenSDA firmware stack; the latest version is available at nxp.com/openSDA. The FRDM-STBC-AGM04 itself contains no active ICs requiring separate driver installation.

Which host boards are compatible with the FRDM-STBC-AGM04?

The FRDM-STBC-AGM04 is mechanically and electrically compatible with all Arduino R3–pinout–compliant NXP Freedom development boards, including FRDM-K64F, FRDM-K22F, and FRDM-KL25Z. It relies on the host board's I²C peripherals and OpenSDA debug interface - no adapter or breakout is needed for standard use.

Can the FRDM-STBC-AGM04 be used with non-NXP microcontrollers?

Yes, the FRDM-STBC-AGM04 can interface with non-NXP MCUs that provide Arduino R3–compatible pin spacing and dual I²C peripherals operating at 1.71–3.6 V logic levels. Signal integrity and pull-up resistor configuration must be verified per host system; the FRDM-STBC-AGM04 itself has no built-in level shifters or bus arbitration logic.

What software tools support the FRDM-STBC-AGM04?

NXP's Sensor Toolbox software (available at nxp.com/sensortoolbox) provides real-time visualization, calibration, and data logging for all three sensors on the FRDM-STBC-AGM04. Firmware examples and Kinetis SDK integration packages are included in the MCUXpresso IDE sensor demo suite. The FRDM-STBC-AGM04 is not supported by generic Arduino IDE sensor libraries out-of-box.

Are the sensors on the FRDM-STBC-AGM04 factory-calibrated?

The MMA8652FC, FXAS21002C, and MAG3110 mounted on the FRDM-STBC-AGM04 retain their factory-trimmed offset and sensitivity parameters, but full 9-DOF sensor fusion requires user-level calibration using NXP's Sensor Fusion Library. The FRDM-STBC-AGM04 does not include additional calibration EEPROM or trim circuitry beyond what is integrated into each individual sensor die.
