The LR1262 Development KIT uses RP2040 as the main control and is equipped with the LR1262 module that supports Lora and LoRaWAN protocols to help users realize development. RP2040 is a dual-core, high-performance, low-power ARM Cortex-M0+ architecture chip, suitable for IoT, robots, control, embedded systems, and other applications. The LR1262 Dev Board is an ultra-low remote transceiver module based on the STM32WLE5CC chip, specially designed for LoRa and LoRaWAN applications.

This board retains various functional interfaces for development, such as the Crowtail interface, which can adapt to 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.
