About This Product

The ES920LR3 is a third -generation 920MHz band radio module equipped with the latest STM32WL (1 chip with RF+MCU). With the RF and MCUs one chip, we realized the low cost and miniaturization of ultra -low power consumption modules without changing the characteristics of wireless. Memory is also increased compared to conventional modules, so it is possible to customize more. The module is compatible with LORA modulation and FSK modulation, and can be switched with commands, so there is no need to update F/W. In addition, for communication, mutual communication with ES920LR / ES920LR2 is possible.

■ Characteristics

･ Long -distance communication by LORA Uses ST Micro Electronics's latest STM32WLE5JC. In areas with good prospects due to the LORA modulation, communications of about 10 km or more are possible, covering areas with a radius of about several km in urban areas. Settings according to the application (transmission speed are variable) can be set according to the combination of bandwidth and diffusion rate. ･ High -speed communication due to FSK modulation Not only LORA modulation but also high -speed communication due to FSK modulation. FSK has a shorter communication distance than LORA, but can be high -speed communication. (Compatible up to 150kbps) ･ Private LORA and LORAWAN protocol can be selected By rewriting the firmware, you can select a protocol for private LORA (Easel's unique protocol) and Lortwan (compliant with ver1.0.4). ･ Higher cost performance The ES920LR3 is equipped with the latest STM32WL with RF+MCU into one chip. With a low -priced ES920LR3, it is possible to communicate with excellent cost performance even in large wireless networks in a wide range of areas and remote areas. ･ Flexible custom support by increasing memory Compared to the conventional modules, the memory has increased, so it is possible to respond to more flexible custom development. ･ Multiple interface support Interface: Compatible with UART, SPI, I2C, ADC, GPIO. MCU: Uses STM32WLE5JC manufactured by ST Micro Electronics. ･ Lineup of two module types that meet your needs External antenna type and wire antenna type can be selected from a total of 2 modules.
