RA-08H LoRaWan Node Board with RP2040 Controller for Long Range Communication (868Mhz/915Mhz)

Description

This Lora module uses RP2040 as the main controller and RA-08H module provides LoRa transmission and reception functions. It supports LoRa point-to-point transparent transmission and LoRaWAN network. When combined with four types of Crowtail sensor modules (Ax2/Dx2/IICx1/UARTx1), it can quickly build a Lora node. Additionally, we provide two firmware versions for 868/915MHZ to meet different usage needs.

To facilitate outdoor use, this module has a built-in lithium battery charging and discharging circuit, and an interface that supports solar panel charging, making it easy to set up and use the node outdoors.

The Lora RA-08H node module has six interfaces that can be used with commonly used sensors such as temperature and humidity, air quality, light, PM2.5, etc., providing convenience for quickly building a Lora weather station, as well as for projects related to smart homes, smart factories, and smart logistics. In addition, we have introduced a 20-pin header and added a double-row pin header in the accessories, which allows you to choose whether to solder it or not, supporting more development options. RA-08H supports programming in both MicroPython and Arduino, making it easy for users to achieve rapid and agile development.

Connect with Crowtail Sensors

It can be connected with 150+ types of Crowtail modules to complete more interesting projects.
