920MHz band LORA/FSK module (ultra -low power consumption) ES920LR2
EASEL
About This Product
ES920LR2 is a 920MHz band radio module that supports LORA modulation and FSK modulation and pursues ultra -low power consumption. The modulation method can be switched with the command and does not need to update F/W, so you can select an appropriate modulation method according to the user application.
In addition, ES920LR2 maintains the ES920LR and pin arrangement, functional compatibility, and can replace the module without changing the customer's board. Since mutual communication with ES920LR is possible, it can be operated in combination with existing radio devices.
■ Characteristics
･ Long -distance communication by LORA
Adopts SX1261 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.
･ High -speed communication by FSK
Also supports high -speed communication due to FSK modulation. FSK has a shorter communication distance than LORA, but can be high -speed communication. (Compatible up to 250kbps)
･ Multiple interface support
Interface: Compatible with UART, SPI, I2C, ADC, DAC, GPIO. MCU: Uses STM32L072CZY manufactured by ST Micro Electronics.
･ Designed with excellent cost performance
ES920LR2 reduces peripheral parts and adopts general -purpose parts by optimizing circuit design to reduce parts cost/adjustment costs. ES920LR2, which can be offered at reasonable prices, can reduce the total system cost even for large wireless networks.
･ 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.
