LoRaWAN RA-08H Development Board Integrated RP2040 with 1.8 “ LCD for Long Range Communication (868Mhz/915Mhz）

Description

Lora technology and Lora devices have been widely used in the field of the Internet of Things (IoT), and more and more people are joining and learning Lora development, making it an indispensable part of the IoT world. To help beginners learn and develop Lora technology better, we have designed a Lora development board specifically for beginners, which uses RP2040 as the main control and is equipped with the RA-08H module that supports Lora and LoRaWAN protocols to help users realize development. RP2040 is a dual-core, high-performance, and low-power ARM Cortex-M0+ architecture chip, suitable for IoT, robots, control, embedded systems, and other application fields. RA-08H is made from the Semtech-authorized ASR6601 RF chip, which supports the 868/915 MHz frequency band, has a 32 MHz MCU built-in, which has more powerful functions than ordinary RF modules, and also supports AT command control.

This board retains various functional interfaces for development, such as the Crowtail interface, which can adapt to our Crowtail module series, the common PIN to PIN header that leads out GPIO ports, and provides 3.3V and 5V outputs, suitable for the development and use of commonly used sensors and electronic modules on the market. In addition, the board also reserves RS485 interface, SPI, I2C, and UART interfaces, which can be compatible with more sensors/modules.

In addition to the basic development interfaces, the board also integrates some commonly used functions, such as a buzzer, a custom button, red-yellow-green three-color indicator lights, and a 1.8-inch SPI interface LCD screen with a resolution of 128*160. We try to minimize the trouble of connecting these components for users when developing and building project prototypes.

We also provide a series of Lora-related products for users to use with the development board to learn and test more functions. You can click here to check it out.
