Chip & Frequency

SX1276/77/78/79 are the classic LoRa chips; the newer SX1262 adds lower power and better sensitivity. Match the band to your region: 915 MHz (US), 868 MHz (EU), 433 MHz where allowed.

Interface

Bare modules speak SPI (most control, most wiring). UART “AT command” or transparent modules are far easier — send bytes in, they come out the other radio. All-in-one boards bundle the MCU too.

Output Power & Sensitivity

Look for +20–22 dBm TX power and sensitivity around -148 dBm. Together they set your link budget — the real driver of range, more than any marketing distance figure.

LoRa vs. LoRaWAN

Raw LoRa P2P is two radios talking directly — simplest. LoRaWAN adds a network layer, gateways and servers like The Things Network. Pick modules with a real LoRaWAN stack if you need that.

Power & Antenna

Most modules are 3.3 V logic — protect them from 5 V boards. Battery projects want low sleep current (SX1262 shines). And a good antenna matched to your band matters more than another few dBm.

Heltec WiFi LoRa 32 V3

⭐⭐⭐⭐⭐ 4.7/5 · Editor’s Choice

The Heltec WiFi LoRa 32 V3 is the module we hand to almost everyone, because it isn’t just a radio — it’s a complete IoT node. An ESP32-S3 brain, an SX1262 LoRa radio, Wi-Fi, Bluetooth LE and a tiny OLED all live on a board the size of two postage stamps, powered and flashed over USB-C with onboard battery management. It runs Arduino, PlatformIO, ESP-IDF and MicroPython, and it’s the de-facto standard for Meshtastic and MeshCore mesh networking, so the community, code and tutorials are vast.

LILYGO T-Beam V1.2

⭐⭐⭐⭐⭐ 4.5/5 · The Tracker

When your nodes move, the LILYGO T-Beam is the one to get. It bolts a NEO-6M GPS, an ESP32, an SX1276 LoRa radio, an AXP power-management chip and an 18650 battery holder onto a single board — everything a portable asset tracker or a Meshtastic node needs in the field. Flash the Meshtastic or SoftRF firmware and you have a pocket GPS mesh device in minutes; or write your own Arduino sketch. Pick the 915 MHz variant for the US (433/868/923 MHz options exist for other regions).

Drop the Waveshare SX1262 LoRa HAT onto a Raspberry Pi’s 40-pin header and you have long-range radio without any soldering. It talks over UART (with an onboard CP2102 USB-UART for debugging), supports the full 915 MHz band, and adds genuinely useful features like wake-on-radio, carrier-sense and a built-in transparent-transmission mode for up to ~5 km. It also works with Arduino and STM32, making it a flexible bridge between a Pi gateway and field nodes.

The Adafruit RFM95W RadioFruit breakout is the maker’s favourite for a reason: it takes the raw SX1276 and adds a 3.3 V regulator and logic level-shifting so it works safely with 3 V or 5 V microcontrollers, plus Adafruit’s superb Arduino and CircuitPython libraries and learn guides. It’s +20 dBm, reaches roughly 2 km on a simple wire antenna (much more with a directional one) and is the smoothest on-ramp to LoRa and even LoRaWAN/The Things Network for hobbyists.

If wiring SPI and learning a radio library sounds like a chore, the REYAX RYLR998 is the antidote. It hides an SX1262 behind dead-simple AT commands over UART — type AT+SEND, the data appears at the other module. It’s FCC/CE/IC certified (important if you ever sell a product), ships with an antenna, and works with any Arduino, ESP32, STM32 or Raspberry Pi using just TX/RX pins. For point-to-point links it’s the fastest path from box to working radio.

The EBYTE E32-900T20D is a workhorse “transparent transmission” module: feed bytes into its UART on one end and they pop out the radio on the other, no protocol to learn. It pushes 20 dBm (100 mW) for a rated 5.5 km, buffers and auto-splits long packets, and runs on 2.3–5.5 V (with 3.3 V TTL signalling). At around $11 with an SMA antenna it’s the value pick for a simple, reliable long-range link between two microcontrollers.

The HopeRF RFM95W is the actual radio inside most of the breakouts above — the bare SX1276-based module, sold here by a US seller for fast shipping. With +20 dBm output and -148 dBm sensitivity it has an excellent link budget, and it’s the right choice when you’re designing your own PCB or integrating LoRa into a product and don’t want to pay for a breakout. The trade-off: it’s a raw 2 mm-pitch module, so you handle level shifting, antenna and soldering yourself.

The Ai-Thinker Ra-02 is the budget classroom and hobby favourite. Built on the SX1278 at 433 MHz, it offers +20 dBm output, -148 dBm sensitivity and an IPEX antenna connector for around $8 — making it the cheapest way to get two microcontrollers talking over a kilometre or more. The lower 433 MHz band penetrates obstacles slightly better than 915 MHz, though check that it’s licence-free in your country. It speaks SPI and works with the popular RadioHead/LoRa Arduino libraries.

For a proper LoRaWAN node with geolocation, this SX1262 + GNSS HAT is the most capable pick here. It pairs an SX1262 LoRa radio with a multi-constellation GNSS receiver on a Raspberry Pi HAT, and ships with example code for The Things Network and ChirpStack — so you’re sending uplinks to a real LoRaWAN server, with GPS position, rather than just doing raw P2P. A magnetic CB antenna and GNSS antenna are included. It’s the priciest module on the list, but it’s also the only true LoRaWAN-plus-GPS solution.

Just Starting Out?

Get the Heltec WiFi LoRa 32 V3 — radio, MCU, Wi-Fi and OLED in one, with the biggest community behind it (~$22).

Tracking Something That Moves?

The LILYGO T-Beam adds GPS and a battery holder — the default for Meshtastic and asset trackers.

Building on Raspberry Pi?

The Waveshare SX1262 LoRa HAT plugs straight onto the GPIO header — no soldering, instant long-range radio.

Want the Easiest Link?

The REYAX RYLR998 (AT commands) or EBYTE E32 (transparent UART) get two boards talking with almost no code.

Need LoRaWAN / The Things Network?

The SX1262 LoRaWAN/GNSS HAT runs a real LoRaWAN stack with GPS — for production-style sensor nodes.

On a Tight Budget?

The Ai-Thinker Ra-02 (~$8) or HopeRF RFM95W (~$13) deliver real LoRa range for the price of lunch.

What’s the difference between LoRa and LoRaWAN?

LoRa is the physical radio modulation — the way bits travel through the air over long distances. LoRaWAN is a networking protocol built on top of LoRa, adding gateways, addressing, encryption and cloud servers like The Things Network. For two devices talking directly (point-to-point), you only need raw LoRa, which is simpler and what most of the modules here do by default. Choose a LoRaWAN-capable module (like the SX1262 LoRaWAN/GNSS HAT) only when you need many nodes reporting to a managed network through a gateway.

Which frequency should I buy — 433, 868 or 915 MHz?

It’s set by your region’s regulations, not preference. Use 915 MHz in North America, 868 MHz in Europe/UK, and 433 MHz only where it’s licence-free for your use. Both radios in a link must be on the same band, and a node must match its LoRaWAN gateway. Buying the wrong band is the single most common LoRa mistake — always pick the variant for your country before checkout.

How far will a LoRa module really reach?

Realistically, a few hundred metres to a couple of kilometres in a typical town, and 5–15 km only with clear line of sight, raised antennas and the slowest data rate (highest spreading factor). The headline “10 km / 15 km” figures are best-case lab numbers. Range depends far more on antenna quality, height and obstructions than on the module itself — a $40 board with a stock antenna at desk height will lose to an $8 module with a good antenna up high.

Can I connect a LoRa module directly to a 5 V Arduino?

Usually not safely. Most LoRa modules (RFM95W, Ra-02, EBYTE E32, REYAX) use 3.3 V logic, and feeding 5 V into their data pins can damage them. Either use a 3.3 V board (ESP32, many STM32s), add a logic level shifter, or pick a module with onboard level shifting like the Adafruit RFM95W breakout, which is explicitly rated for 3–5 V logic. The all-in-one boards (Heltec, T-Beam) already handle this internally.

What’s the easiest LoRa module for a complete beginner?

For two devices talking to each other with minimal code, the REYAX RYLR998 (simple AT commands) or the EBYTE E32 (transparent serial) are the gentlest start. If you want a single board that’s also a microcontroller with a screen, the Heltec WiFi LoRa 32 V3 plus the Meshtastic firmware lets you build a working long-range messenger without writing any code at all.
