LoRa32u4 II Lora LiPo Atmega32u4 SX1276 HPD13 868MHZ EU Antenna

LoRa32u4 II is a light and low consumption board based on the Atmega32u4 with 868MHZ / 915Mhz high quality LoRa module and USB LiPO battery charging circuit.  -This board can reach 7KM range in SF8 (full line of sight).

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 others. This version is 868Mhz, suitable for EU and other area. A 915Mhz version is available for US (and others area) as well as a 433Mhz version (China and other area).

The ATmega32u4 is clocked at 8 MHz and working at 3.3 V. This chip has 32 K of flash, 2 K of RAM. It offers 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 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.

Based on the HPD13 LoRA wireless module, using high-performance, highly integrated RF transceiver chip SX1276 design. Advanced LoRaTM spread spectrum communication technology to ensure greatly improved communication distance and anti-jamming capability of the module, while achieving a very low current consumption. In the LoRa® mode, the HPD13 provides higher reception sensitivity performance, more robust anti-jamming capability, and improved communication distance and reliability compared to similar transmit and receive modules on the market. In normal (G) FSK mode, it also provides industry-specific receiver sensitivity, as well as very high communication rates.
