The STEVAL-IKR002V7D evaluation board is an efficient device from STMicroelectronics that is built with STM32L010RF, a proprietary range extension eNB device based on the STM32L010 microcontroller. This simple evaluation board is designed for use in long-range low-power RF applications.

The board’s main purpose is to extend the range of a communication link beyond the usual limitation of signal loss. The symmetrical design of the board allows any two STEVAL-IKR002V7D boards to communicate with each other by using a single pair of antennas. This makes it a great tool for testing and development of range-extending links.

The STEVAL-IKR002V7D board includes an RF transmitter and receiver, both of which are powered by the STM32L010 microcontroller. The STM32L010 microcontroller uses an embedded Flash memory and a DSP core to process commands received through the RF link. The board also includes a host PC interface, which allows it to connect to a PC for data and program transmission and analysis.

Working Principle:

The STEVAL-IKR002V7D board uses a combination of frequency-agile radio-frequency (RF) receiver and transmitter for operation. The RF transmitter and receiver are both controlled by the STM32L010 microcontroller. Upon receiving a signal from the other board, the STM32L010 microcontroller processes the received data using a DSP engine and decodes the signal. If a valid communication link is detected, the board sends the signal to the host PC interface for further processing.

In addition, the STEVAL-IKR002V7D board has an integrated transceiver. The transceiver is used to receive and transmit data from the host PC. The transceiver supports a range of protocols, including Bluetooth, Wi-Fi, and IEEE 802.15.4. These protocols allow the board to communicate with other wireless devices, like cell phones, laptops, and other IoT systems. The board also features low-power mode support to ensure maximum range even when operating in challenging environmental conditions.

The board includes a USB interface, which can be used to program the STM32L010 microcontroller. Through this interface, users can easily customize the settings of the RF link. Additionally, the STEVAL-IKR002V7D board can be used with STMicroelectronics’ free STM32CubeIDE software package to develop custom applications.

With its range extension capabilities, the STEVAL-IKR002V7D evaluation board is the perfect device for testing and developing applications requiring reliable, low-power, and long-range communication links.
