M5Stack LoRaWAN US915 Unit for Long-Range IoT Nodes

The M5Stack LoRaWAN US915 Unit adds long-range wireless communication to remote sensors and embedded controllers. Built around STM32WLE5, it supports the US915 902–928MHz band, LoRaWAN 1.0.3, Class A, B, and C operation, OTAA and ABP activation, plus direct LoRa P2P links.

The host connects through UART at a default 115200 baud rate and configures the radio with AT commands. This keeps application logic on the main controller while the unit handles LoRaWAN joining, network communication, and P2P operation.

Confirm US915 Compatibility Before Deployment

Use this version only where the gateway, network server, and local radio regulations support a compatible US915 channel plan. It is not a substitute for EU868 or CN470 hardware. A regional mismatch can appear as failed joins, missing uplinks, or unreliable coverage even when credentials and application code are correct.

LoRaWAN Network or Direct P2P

Choose LoRaWAN mode when distributed nodes report through a compatible gateway and network server. Choose P2P when two devices need a direct local link without a gateway. The unit supports both workflows, which makes it practical for gateway-based telemetry and device-to-device prototypes.

Class A, B, and C Power Profiles

Class A suits periodic low-power nodes with limited receive windows. Class B adds scheduled receive opportunities. Class C keeps receive windows available more continuously for responsive downlinks at higher power use. Select the class around reporting interval, downlink latency, and battery budget.

Plan Range and Power from Real Conditions

The product specification lists P2P distances up to 2300m at 125Kbps and 1300m at 500Kbps under stated test conditions. Actual range depends on antenna placement, terrain, buildings, interference, data rate, installation height, and link budget. Sleep current is specified at about 28.61µA at 5V; complete battery calculations must also include the host controller, sensors, wake cycle, and transmit duty.

Technical setup details are available in the M5Stack LoRaWAN US915 documentation.

How can I confirm product compatibility?

Check the product specifications, operating voltage, communication interface, dimensions, connector type, and software requirements before ordering. Compatibility may also depend on your controller, operating system, development framework, library version, and project wiring.

If you are unsure, contact us before purchasing and include your controller model, intended application, power source, and any other hardware you plan to use. We will help you identify the most suitable option, but we cannot guarantee that every product will work with every platform or project.

Does the product come with a warranty?

Warranty coverage may vary by product and manufacturer. If your order arrives damaged, incomplete, or appears to have a manufacturing defect, contact us as soon as possible with your order number, product model, and clear photos or videos of the issue.

Our team will review the information and provide the appropriate next step according to the applicable product and after-sales policy. Damage caused by incorrect wiring, unsuitable voltage, unauthorized modification, soldering, misuse, or operation outside the documented specifications may not be covered.

How long does shipping take?

LogicBoundless provides worldwide shipping, with primary service coverage across the United States, Europe, and Asia. Orders are generally fulfilled from Shenzhen, China, and tracking information is provided after dispatch.

Processing and delivery times depend on product availability, destination, customs clearance, and the selected shipping service. Please review the Shipping Information page for the latest estimated delivery times and shipping conditions.

What is your return policy?

Eligible products may be returned within 30 days of delivery. Returned items must be unused, unsoldered, unmodified, and kept in their original condition with all packaging, cables, accessories, manuals, and included components.

Please contact support@logicboundless.com before sending anything back. Returns made without prior approval may not be accepted. Original shipping charges are generally non-refundable unless the return is caused by a verified product defect or fulfillment error.

Can you help if I have a technical problem?

Yes. LogicBoundless provides practical technical guidance for product setup, wiring, power, communication, code, and configuration issues.

To help us understand the problem efficiently, please provide your controller model, wiring photos, power source, code, library or firmware versions, expected behavior, and complete error messages. We cannot promise that every component will work in every system, but we will help you identify the likely cause and the next practical troubleshooting step.

Can I change or cancel my order?

Contact us as soon as possible if you need to change or cancel an order. We will try to assist before the order enters processing or is handed to the shipping carrier.

Once an order has been packed or dispatched, it may no longer be possible to change the products, delivery address, or shipping method. In that case, the standard return process may apply after delivery.
