2.4GHz RF Wireless Transreveiver Module

Product Details:

The SX1278 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using Semtech’s patented LoRaTM modulation technique SX1278 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials.

The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The SX1278 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.

The NRF905 is a wireless transceiver module that operates on the 2.4 GHz ISM band and is used for low-power wireless communication. It is designed for applications such as wireless sensor networks, remote control systems, and data transmission over short to medium distances.

Key Features of the NRF905:

1. Frequency Range:

   • Operates in the 2.4 GHz ISM band, a globally available frequency range used for many wireless communications.

2. Low Power Consumption:

   • The module is designed for low-power applications, making it suitable for battery-powered devices such as wireless sensors and remote control devices.
   • Supports low-power modes, which allows the module to save energy when idle.

3. Data Rate:

   • The NRF905 can transmit data at rates of up to 100 kbps (kilobits per second), which is sufficient for most sensor data transmission and remote control applications.

4. Wide Range of Communication:

   • The module supports communication over distances up to 200 meters in open space with a 100 mW transmission power, which is typical for wireless modules operating at this frequency.

5. Communication Protocols:

   • Supports the Serial Peripheral Interface (SPI), which allows easy integration with microcontrollers such as Arduino and Raspberry Pi.
   • The NRF905 uses a simple protocol to handle both sending and receiving of data, which simplifies communication.

6. Built-in Antenna:

   • The module has an integrated antenna, which reduces the need for external components in most basic applications.

7. Multiple Addressing:

   • It supports multiple device addressing, allowing communication between different modules without interference from other devices.

8. Automatic Packet Handling:

   • The module can handle automatic packet recognition, addressing, and error correction, which makes it suitable for robust communication in noisy environments.

9. Range Extension:

   • By using external antennas (in some configurations), the range of the module can be extended beyond the standard range of the built-in antenna.

Technical Specifications:

• Frequency Range: 2.400 GHz to 2.483 GHz (ISM band)
• Data Rate: 100 kbps
• Modulation: GFSK (Gaussian Frequency Shift Keying)
• Power Supply: 1.9V to 3.6V
• Transmission Power: Up to 100 mW
• Receiver Sensitivity: -100 dBm
• Communication Interface: SPI
• Range: Up to 200 meters in open space (depends on antenna and power settings)
• Standby Current: 3 µA (in low-power mode)
• Transmission Time: Typically 0.5 ms per packet (at 100 kbps)

RFM23B-433-D is a versatile wireless data transmission module (integrated transmitter and receiver track on a single circuit board) designed for work over the 433MHz ISM Band. The high sensitivity of the receiver (-121dBm) and the transmitter output power of +20dBm guarantee a stable and interference-resistant communication between the devices. To control RFM23B-433-D with a microcontroller, the user can use programmable GPIO lines (General Purpose Input Output), as well as a four-wire serial bus (Serial Peripheral Interface). Proper data transmission is possible thanks to two 64-byte TX/RX FIFO buffers. RFM23B-433-D is also available in the THT version (contact pitch: 2mm) with a 17x14mm circuit board.
