STMicroelectronics STEVAL-IDB007V1

Overview

STEVAL-IDB007V1 from STMicroelectronics is an Arduino-compatible evaluation platform built around the BlueNRG-1 Bluetooth® Low Energy 4.2 system-on-chip, featuring +8 dBm RF output power, -88 dBm receiver sensitivity, 7.7 mA RX / 8.3 mA TX current draw, integrated balun, and on-board LSM6DS3 (3D accelerometer + gyroscope) and LPS25HB (MEMS pressure + temperature) sensors.

For engineers reviewing the STEVAL-IDB007V1 datasheet, STEVAL-IDB007V1 pinout, STEVAL-IDB007V1 application, or STEVAL-IDB007V1 equivalent, this board supports rapid prototyping of BLE sensor nodes, remote control interfaces, USB debug-enabled firmware development, and low-power IoT edge devices requiring simultaneous master/slave role operation.

Technical Context

The platform integrates the BlueNRG-1 SoC with a dedicated STM32L151CBU6 microcontroller for USB-to-serial bridging and host-side firmware management, enabling dual-role BLE communication while offloading UART/USB protocol handling. It supports three independent power domains: USB 5 V, coin-cell battery (CR2032), and external supply - each configurable via jumpers for precise current measurement and runtime profiling.

Hardware resources include SMA antenna connector, JTAG/SWD debug interface (2×10 header), Arduino UNO R3 pin-compatible headers (DIO0–DIO14, analog inputs, SPI/I²C), 3 user LEDs, 2 tactile buttons, and dedicated current-sense jumper (JP1) for isolating BlueNRG-1 supply current during power optimization.

FAQ

Does STEVAL-IDB007V1 support Bluetooth 5.0 or later?

No. The board is based exclusively on the BlueNRG-1 SoC, which implements Bluetooth Low Energy v4.2 only. It does not support Bluetooth 5.0 features such as 2 Mbps PHY, LE Long Range, or enhanced advertising capacity. Firmware updates cannot extend the underlying radio specification.

Can the LSM6DS3 and LPS25HB sensors be used simultaneously with BLE transmission?

Yes. The BlueNRG-1 SoC provides dedicated I²C interfaces (I2C2_CLK/I2C2_DAT) and GPIO control lines to operate both sensors concurrently with active BLE advertising or connection. Sensor data can be streamed over BLE GATT services without interrupting radio operation.

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

Yes. The SMA connector is impedance-matched to 50 Ω and directly interfaces with spectrum analyzers, network analyzers, and calibrated RF signal generators. Measured RF performance (+8 dBm output, -88 dBm sensitivity) was validated using this connector per ST's characterization methodology.

What development software tools are officially supported?

ST provides the BlueNRG SDK (v2.x), STSW-BLEGUI (PC GUI), and STM32CubeMX + TrueSTUDIO/IAR EWARM for firmware customization. The board is natively recognized as a CDC ACM device under Windows/macOS/Linux for serial debugging and OTA firmware updates via ST's BlueNRG-1 Flasher utility.
