SENS\'IT Discovery 3.4 is a wireless data communication system widely used in the fields of wireless sensor networks (WSN). It is composed of a radio transceiver, an MCU choice, a low power radio module, a SYSTICK timer, a motor driver, a real time clock, a low power analog to digital converter (ADC), and several sensors. It is an integrated solution for RF communication, positioning, timing, power controlling, and data acquisition. The system also provides scalable modular architecture with open interfaces, which allows customers to build their own applications based on their specific requirements.

RF Receiver, Transmitter, and Transceiver Finished Units are the core components of SENS\'IT Discovery 3.4. The transceiver module works in the 900 MHz ISM band and can be used in multiple data low power radio applications. It is a low power, low cost 2-way half-duplex transceiver based on the Nordic Semiconductor nRF24AP2 MCU. It supports a crystal-less and low-power-clock-based architecture for operation. It is integrated with an ultralow power SysTick counter and a 4-channel 10-bit DAC for analog signal measurement and generation. The transceiver module also provides a low-power RF link for multiple data functions and comes with a variety of peripheral sensors needed for basic data acquisition.

The RF receiver module of the SENS\'IT Discovery 3.4 is based on the Nordic nRF24L01 radio transceiver and uses the latest low-power consumption technology. It has a sensitivity range of -94 dBm and a low receive power supply of 0.3 mA. With its flexible antenna configuration and power supply, the receiver module is suitable for use in various radio communication topologies.

The RF transmitter module, on the other hand, supports a maximum output power of up to +19 dBm and an applicable output power range of 14 dBm to 19 dBm. The transmitter module is completely integrated with an onboard MCU, a low-power 32-bit cortex-M0 processor, a low-interrupt software, an analog-to-digital converter module, and an onboard power management. It is also equipped with an Arm TrustZone security module and a separate embedded microcontroller for executing user application code.

All the components of the SENS\'IT Discovery 3.4 system are connected to each other through the on-board serial peripheral interface (SPI), which enables communication between the various modules and enables data transmission in an organized manner. The SPI bus is also connected to the host PC, allowing the users to access, monitor, and configure the system remotely through a user-friendly GUI interface.

In conclusion, SENS\'IT Discovery 3.4 is an integrated wireless communication system, which offers an array of components such as RF receivers, transmitters, and transceiver finished units. It has a range of power savings features and is suitable for low-data-rate, low-power consumption applications such as wireless sensor networks. All the components are interconnected using the SPI bus, making it easy to access, configure, and monitor the system remotely.
