Elecrow New Product Arrival 🔥🎉

This module uses RP2040 as the main controller and the 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 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 Arduino and MicroPython, making it easy for users to achieve rapid and agile development.
