Product Description
Features of LoRa32u4 II Lora Development Board
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.
