920MHz band LORA Module ES920LR
EASEL
About This Product
ES920LR is a 920MHz band long -range wireless module that uses LORA modulation. It can be used for various IoT systems because the wide area area can be connected with a star -type network.
With EASEL's unique private LORA specifications, you can optimize the installed software according to the user application.
■ Characteristics
･ Long -distance communication by LORA
Adopts SX1276 made of Semtech compatible with LORA modulation. In areas with good prospects, communications of about 10 km or more are possible, covering areas with a radius of several km. Settings according to the application (transmission speed are variable) can be set according to the combination of bandwidth and diffusion rate.
･ Multiple interface support
Interface: Compatible with UART, SPI, I2C, ADC, DAC, GPIO. MCU: NXP MKL16Z128 is adopted.
･ Designed with excellent cost performance
The ES920LR reduces peripheral parts and adopts general -purpose parts by optimizing the circuit design to reduce parts cost/adjustment costs. ES920LR, which can be offered at reasonable prices, can reduce the total system cost even for large wireless networks.
･ Private LORA and LORAWAN protocol can be selected
By rewriting the firmware, you can select a private LORA (EASEL proprietary protocol) and Lorawan protocol. LORAWAN complies with Japanese specification Ver1.0.2.
If it is a private LORA, you can confirm communication immediately after obtaining the development/evaluation kit of the ES920LR. * If the firmware is LORAWAN, you need to prepare a Lorawan gateway yourself.
･ Lineup of 4 module types that meet your needs
It can be selected from a total of 4 modules, an external dipole antenna type, a wire antenna type, and an antenna type evaluation and development module.
