STMicroelectronics STEVAL-STLCS01V1

Overview

STEVAL-STLCS01V1 from STMicroelectronics is a compact, solderable or pluggable sensor node development module integrating an STM32L476JG ultra-low-power Cortex-M4F MCU, LSM6DSM 6-axis inertial sensor, LSM303AGR eCompass, LPS22HB barometer, MP34DT05-A digital microphone, and BlueNRG-MS Bluetooth 5.0 LE network processor - enabling rapid prototyping of wireless environmental and motion monitoring systems.

For engineers reviewing the STEVAL-STLCS01V1 datasheet, STEVAL-STLCS01V1 pinout, STEVAL-STLCS01V1 application, or STEVAL-STLCS01V1 equivalent, this module delivers validated firmware examples, mobile app integration via STBLESensor (iOS/Android), and regulatory-compliant RF design with FCC/IC/CE certifications - critical for IoT edge node development and sensor fusion evaluation.

Technical Context

The module implements a complete sensor hub architecture: the STM32L476JG executes sensor fusion algorithms and manages peripheral interfaces (I²C, SPI, SAI, UART, DFSDM, USB OTG), while BlueNRG-MS handles BLE 4.1/5.0 protocol stack offload. All sensors operate in low-power mode with configurable ODRs and embedded FIFOs.

Power management is centralized via LD39115J18R (1.8 V, 150 mA, <1 µA quiescent current), supporting 2–5.5 V input. The BALF-NRG-02D3 balun ensures matched 50 Ω RF output to the BlueNRG-MS antenna interface, with default TX power set at 0 dBm per FCC/IC certification.

FAQ

Is STEVAL-STLCS01V1 pin-compatible with STEVAL-STLKT01V1?

No. STEVAL-STLCS01V1 is the bare sensor node module (13.5 × 13.5 mm, 18-pad solderable or connectorized), while STEVAL-STLKT01V1 is the full kit including cradle board, battery, and accessories. Their mechanical interfaces differ: the module uses a dedicated 18-pad footprint or bottom-edge connector, not direct pin mapping to the cradle.

Can the Bluetooth transmit power be increased beyond 0 dBm?

Yes - firmware reprogramming allows BlueNRG-MS TX power adjustment up to +8 dBm. However, doing so voids the existing FCC/IC certifications (S9NSTILE01 / 8976C-STILE01); full radiated emission retesting in the target host system is mandatory before commercial deployment.

What debug interface does STEVAL-STLCS01V1 support?

The module provides a standard 4-pin SWD (Serial Wire Debug) interface via dedicated test points, compatible with ST-LINK/V2-1 and other ARM Cortex debug probes. No onboard debugger is included - external programming and real-time tracing require connection to a supported ST-LINK adapter.

Does STEVAL-STLCS01V1 include production-ready firmware?

It ships with factory-loaded firmware supporting basic sensor streaming and BLE advertising via STBLESensor app. Full source code, middleware (X-CUBE-MEMS1, X-CUBE-BLE1), and example projects are provided in STM32CubeIDE-compatible packages - intended for evaluation and customization, not drop-in production use without validation.
