EVESKY

EVESKY 433 MHz LoRa Wireless USB Transceiver Module x 2

SKU CH-6JMM-HZJ95

Two 433 MHz LoRa USB transceivers enable long-range encrypted data links with relay networking and simple pairing

  • Long-range LoRa spread spectrum reaches distant nodes
  • Remote parameter configuration simplifies field setup
  • Multi-level relay networking extends coverage further
  • Paired modules connect instantly for fast deployment
  • Encrypted transmission secures data across the link

LoRa USB Transceiver Pair

The EVESKY 433 MHz LoRa Wireless USB Transceiver Module ships as a matched pair for point-to-point or relayed data links. It suits engineers, hobbyists and system integrators who need transparent serial bridging without writing custom RF firmware. Modules enumerate as virtual COM ports for immediate host software integration.

Thermal and Power Profile

Each module draws power directly from the USB bus and runs cool during continuous transmit cycles. LoRa spread-spectrum modulation keeps the radio in low-duty-cycle operation, so audible noise is absent and thermal throttling does not occur. No external supply or heatsink is required for normal indoor or outdoor deployments.

433 MHz ISM Band Operation

The radios operate in the 433 MHz licence-exempt band, which determines range, penetration and regulatory suitability. Encryption and multi-level relay networking extend reliable distance, but the fixed frequency means the kit cannot be used where 433 MHz is restricted or where a different ISM band is mandated.

Highlights

  • Long-range LoRa spread spectrum reaches distant nodes
  • Remote parameter configuration simplifies field setup
  • Multi-level relay networking extends coverage further
  • Paired modules connect instantly for fast deployment
  • Encrypted transmission secures data across the link

Questions about this item

How do I install the EVESKY 433 MHz LoRa USB transceiver modules and which step is commonly missed?

Plug both modules into USB ports, then use the paired communication feature to complete the easy pairing process; the step often missed is confirming the encryption setting is enabled for secure data transmission.

What maintenance or replacement will the EVESKY 433 MHz LoRa USB transceiver modules need over time?

No routine maintenance is required; the solid-state modules have no moving parts, so replacement is only necessary if physical damage occurs or if the USB connector wears out after extensive insertion cycles.

What is the first limit that appears when the EVESKY 433 MHz LoRa USB transceiver modules run under sustained use?

The primary limit under continuous operation is the USB port power budget, which can restrict transmission duty cycle if the host cannot supply sufficient current for prolonged LoRa spread spectrum activity.
