=Features=
* AI Thinker RA-02 LoRa module based on the SX1278 LoRa transceiver.
* Supports LoRaWAN protocol for long-range communication.
* Frequency: 433MHz (or other regional LoRa frequencies as per regulations).
* Spread spectrum communication with high noise immunity.
* Low power consumption and deep sleep support.
* Data transmission up to 10 km in open environments.
* SPI interface for communication with the ESP32-CAN-X.
* Compact SMD package with 16 pins (8 on each side).
* External antenna support via u.FL (IPEX) connector.

=Getting Started=
==Components==
The LoRaWAN Bolt-on includes:
* AI Thinker RA-02 LoRa Module
* Custom Printed Circuit Board (PCB)
* 2 x 20-pin Headers (available separately)

==Hardware Connection==
The RA-02 module is an '''SMD package''' and will be '''directly soldered onto the PCB.'''When stacking the LoRaWAN Bolt-on onto the ESP32-CAN-X development board, ensure proper alignment of the icons on the boards, particularly the LoRa antenna and USB positions, to maintain correct functionality.

==Separate Headers==
Additionally, '''2 x 20-pin''' headers must be soldered onto the PCB to provide the necessary connections. These headers are available from various sources such as Amazon and eBay (male/female versions available).
