915MHz LoRa Wireless Transmitter Shield for Arduino (RFM95W)

A ready-to-fit LoRa shield for 915 MHz

This LoRa shield is a long-range transceiver in an Arduino shield form factor. LoRa lets you send data and reach extremely long ranges at low data rates, using ultra-long-range spread-spectrum communication with high interference immunity and low power draw, which is why it is popular for remote sensors and telemetry.

It is pre-configured for the 915 MHz band and is built around the RFM95W or RFM98W chipset, and it plugs directly onto Arduino Leonardo, Uno, Mega2560 and DUE boards, compatible with both 3.3 V and 5 V I/O.

Specifications and features

An external antenna connects through an SMA jack. The shield includes automatic RF sense and CAD (channel activity detection) with ultra-fast AFC, a packet engine handling up to 256 bytes with CRC, low power consumption, and a built-in temperature sensor and low-battery indicator.

Because it is pre-configured for 915 MHz, check your local regulations for that band before you transmit, and pair it with a matching receiver shield or module on the other end of the link.

Who it is for

Makers in regions that use the 915 MHz LoRa band who want a simple, shield-based way to add long-range wireless to an Arduino project.

Pairing it with a receiver

For a working link you need a matching receiver, whether that is a second RFM95W/RFM98W shield, a bare module wired to another microcontroller, or a LoRa gateway. Set the same frequency, spreading factor and bandwidth on both ends, and start testing at short range indoors before trying a long outdoor link.
