Another platform that is worth mentioning is VESNA [1]. VESNA is a modular and fully flexible platform employed for the development of wireless sensor networks.It is based on a high-performance microcontroller with ARM Cortex-M3
core and radio interface spanning over multiple ISM frequency bands. VESNA is a core module and a set of special feature modules (sensor node radio – SNR, sensor node expansion – SNE, sensor node power – SNP) that are used as/if needed. The platform features various peripherals including UART, I2C, SPI, USB, ADC and DAC. All these allow hosting of different sets of sensors and/or actuators including sensors for temperature, humidity, luminance, color, reflectance, pressure, presence, location, sound, acceleration, gasses, motion, range, and actuators such as motor, relay, servo, alarm.
