Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Core1262-868M is a compact LoRa core module based on the new-generation SX1262 chip. It operates in the Sub-GHz band (HF: 850–930 MHz) and suits long-range communication for industrial, smart-home, and data-acquisition scenarios. Combined with a LoRa gateway, it can build a LoRaWAN network.

Technical overview

RF chip: Semtech SX1262; modulation: LoRa/(G)FSK.
Operating voltage: 3.3 V; transmit current ~45 mA at 14 dBm, receive current ~5.3 mA at 125 kHz bandwidth.
Transmit output power: up to +22 dBm.
Operating temperature: -40 °C to +85 °C.
Dimensions: 19.00 × 22.00 mm.
Interfaces: SPI (max. 18 MHz), BUSY, RESET, RXEN/TXEN, and DIO1–DIO3 pins.
HF version covers 850–930 MHz; the LF variant covers 410–490 MHz.
Network join uses OTAA or ABP; the example uses OTAA with a Join-Request over regional channels (e.g., 868.10 / 868.30 / 838.50 MHz in Europe).

Notes and version constraints

Exact frequency bands depend on local radio regulations; verify applicable ISM bands before deployment.
OTAA requires server-side registered DevEUI/AppEUI/AppKey; without valid registration, network access will fail.
The source text contains template placeholders ({{{name2}}}, etc.), so some specifications may be incomplete – values such as transmit output power should be verified against the datasheet.
Exact configuration of DIO pins and the RF switch is version-dependent; consult datasheet chapters 8, 10–12 before integration.
