STMicroelectronics STEVAL-IDB010V1

Overview

STEVAL-IDB010V1 from STMicroelectronics is a Bluetooth® Low Energy evaluation platform based on the BlueNRG-LP SoC (WLCSP49), integrating an Arm Cortex-M0+ core, 256 kB flash, 64 kB SRAM, MEMS accelerometer/gyroscope (LSM6DSOX), pressure/temperature sensor (LPS2X), and digital MEMS microphone (MP34DT05-A). It supports +8 dBm output power, -103 dBm sensitivity at 125 bps long range, and simultaneous master/slave roles for BLE development.

For engineers reviewing the STEVAL-IDB010V1 datasheet, STEVAL-IDB010V1 pinout, STEVAL-IDB010V1 application, or STEVAL-IDB010V1 equivalent, this board enables rapid prototyping of wireless sensor nodes, BLE gateway interfaces, low-power edge AI inference, and audio-enabled IoT endpoints with Arduino R3 compatibility and CMSIS-DAP debug support.

Technical Context

The platform centers on the BlueNRG-LP SoC - a 64 MHz Arm Cortex-M0+ with integrated BLE 5.2 radio, supporting 2 Mbps PHY, long-range mode, extended advertising, GATT caching, and path loss monitoring. Its peripheral set includes dual I²C, dual SPI/I²S, UART/USART, PDM, 12-bit ADC, and six PWM channels.

On-board sensors provide synchronized inertial (6-axis LSM6DSOX), environmental (LPS22HB pressure/temperature), and acoustic (MP34DT05-A PDM microphone) data acquisition. Power is managed via USB, CR2032 battery, or external supply, with LDO regulation and VBRD/VBLUE rail separation for RF/analog integrity.

FAQ

Does STEVAL-IDB010V1 support Bluetooth 5.2 features like LE Audio or Isochronous Channels?

No. The BlueNRG-LP SoC on this board implements Bluetooth 5.2 specification features including 2 Mbps PHY, Long Range, Extended Advertising, GATT Caching, and Path Loss Monitoring - but does not include LE Audio or Isochronous Channels, which require later-generation radios like BlueNRG-3 or SPBTLE-RF.

Can the onboard MEMS microphone be used for voice wake-word detection?

Yes. The MP34DT05-A provides PDM output sampled at up to 1.6 MHz, compatible with BlueNRG-LP's PDM interface. With firmware implementing spectral analysis or lightweight neural inference (e.g., using CMSIS-NN), it supports keyword spotting - though no pre-trained model is included in the default STSW-BNRGLP-DK package.

Is the UFL antenna connector compatible with standard 50 Ω RF test equipment?

Yes. The UFL connector is directly matched to 50 Ω and calibrated for operation at 2.4 GHz. The antenna matching network (L1, C10, C21, C15) ensures <1.5:1 VSWR across the BLE band, enabling accurate conducted RF measurements including output power, EVM, and receiver sensitivity without external tuning.

What are the voltage domains for VBRD and VBLUE rails, and why are they separated?

VBRD supplies digital logic (MCU core, sensors, USB interface) at 3.3 V; VBLUE powers the BlueNRG-LP RF section and analog front-end at a regulated 1.8 V. This separation minimizes digital noise coupling into the sensitive BLE receiver chain, maintaining -103 dBm sensitivity and meeting ETSI EN 300 328 radiated emission requirements.
