DIYmall LoRa32u4 RA02 RA-02 Long Range communication 1KM module LiPo Atmega328 SX1278 for Arduino

Description:
LoRa32u4 is a light and low consumption board based on the Atmega32u4 and 433MHz LoRA module RA02 from AI-Thinker and an USB battery charging circuit. Ideal for creating long range wireless networks that can exceed 2.4 GHz 802.15.4 and similar, it is more flexible than Bluetooth LE, does not require high power unlike WiFi and offers long range.

The  RA02 LoRa module is fitted with an U.FL (IPX) external antenna connector.
The ATmega32u4 is clocked at 8 MHz and 3.3 V. This chip has 32 K of flash, 2 K of RAM and built-in USB to Serial communication, debugging and programming capabilities without the need for an external FTDI chip, it can also act as an HID device (mouse, keyboard, USB MIDI device, etc).
This board is also equipped with a LiPo and Liion charging circuit and a standard battery interface. It is fully compatible with Arduino. A white user led is tied to pin 13. An orange LED is used for charging status.
