It comes with an antenna connector 915MHz. This shield will provide your Arduino with Long Range communication capability.

Board Features:

• Dimensions: 53mm x 64mm
• Integrated LDO 3.3V up to 500mA
• Works directly with any Arduino regardless of the working voltage (5V/3,3V)
• Integrated LoRa Class A modem RN2903 (915MHz)
• Device Firmware Upgrade (DFU) over UART
• Option to choose the uart communicating with the radio (Soft / Hard)
• GPIO0 for LED status

LoRa technology is a proprietary wireless technology developed by Semtech Corporation. It utilizes a spread spectrum modulation in the Sub-GHz band to enable long range (greater than 10 miles) coverage, low power consumption (up to 10 years battery power), high network capacity (up to 1 million nodes), robust communication, and localization capability.

• LoRa technology is capable of demodulating 20 dB below noise level, significantly improving immunity to the interference when combined with integrated forward error correction.
• LoRa technology has high sensitivity, -148 dBm, enabling extremely long range connectivity.

Microchip LoRa Technology Module:

• Embedded LoRaWAN Protocol Class A - easily connects to LoRa Technology gateway
• LoRaWAN Protocol Stack ready in system
• Simple ASCII command set
• Full certification by region

The bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. RF Connector, SMA Right Angle PCB Jack, Through Hole, 50 Ohm, Reverse Polarized

Items included:

• 1 x RN2903 LoRa Shield
• 1 x SMA Right Angle Male Antenna
