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, a Lora development board has been designed 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 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, the common PIN to PIN header that leads out GPIO ports, and provides 3.3 V and 5 V 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 128x160.
Features
- Uses RP2040 as the main controller, with two 32-bit ARM Cortex M0+ processor cores (dual-core), and provides more powerful performance
- Integrates the RA-08H module with 32 MHz MCU, supports the 868 MHz frequency band and AT command control
- Abundant external interface resources, compatible with Crowtail series modules and other common interface modules on the market
- Integrates commonly used functions like buzzer, LED light, LCD display and custom button, making it more concise and convenient when creating projects
- Onboard 1.8-inch 128x160 SPI-TFT-LCD, ST7735S driver chip
- Compatible with Arduino/Micropython, easy to carry out different projects
