🚩 LoRa32u4 II is a light and low consumption board based on the Atmega32u4 and HPD13 915MHz LoRA module and an USB battery charging circuit
🚩 Interface Type: SPI
🚩 HPD13 wireless module: high-performance, highly integrated RF transceiver chip SX1276, Long communication distance, high anti-jamming, low current consumption, higher reception sensitivity performance
🚩 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.
1. Does not require high power unlike WiFi, but offers long range.
2. 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.
3. It can also act as an HID device (mouse, keyboard, USB MIDI device, etc).
4. This board is also equipped with a LiPo and Liion charging circuit and a standard battery interface. It is fully compatible with Arduino.
