The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM (Industry, Science and Medicine) band, a set of frequencies set aside for low-power, short-range, license-free radios. It’s perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation, citizen science and more.
Elecrow Lora Shield is a long range transceiver on a Arduino shield form factor and based on Open source library. This shield allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
This accessory board helps you use the NRF24L0 Module more easily. It uses the I2C (TWI) communication protocol to communicate with other controller such as the Arduino thus to simplify the NRF24L01 communication. With this module, you do not need to understand the tedious communication process of NRF24L01 anymore, building NRF24L01 wireless application...
The 32u4 with LoRa RFM95 IOT Board consists of the ATmega24u and the wireless transport module RFM95.
This module uses the newest 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature.
NRF24L01P + PA + LNA wireless module operates in Free license 2.4G ISM band, you can do point to point application and can also be composed of star network. Because of it's small size 45.54 x 16.46 mm, it easy to embed in any space-constrained products.
The Lora RFM95 IOT Board for RPI consists of the wireless transport module RFM95.
