Seeed Studio Studio Wio-SX1262-LF LoRa Module (433/470MHz, SX1262)

The module communicates with a host microcontroller exclusively via an SPI interface. You must connect the module's SPI pins (MOSI, MISO, SCK, CS) and a reset line to your MCU's corresponding GPIOs. Ensure your firmware initializes the SPI peripheral at the correct clock speed and uses a library like RadioLib or the Semtech provided drivers to handle LoRa packet transactions and configuration.

Band selection is performed through firmware configuration. Using the SPI interface, you send specific register write commands to the SX1262 chipset to set its operating frequency center. You must ensure your antenna is tuned for the selected band. The module itself does not have a physical switch; the frequency is entirely software-defined within the supported ranges specified in the datasheet.

The module requires a stable 3.3V power supply. For optimal performance and to achieve the specified ultra-low sleep current of 1.62 µA, you must correctly sequence the module into sleep mode via SPI commands, typically setting the DIO3 pin as an interrupt or enabling the internal watchdog timer. Ensure your power rail can supply the peak transmit current of up to 106mA when the module is actively sending data at full power.

Yes, the Wio-SX1262-LF is fully compatible with LoRaWAN protocol stacks. You need to implement a LoRaWAN end-device stack (such as LoRaMac-node or Arduino LMIC) on your host microcontroller. This stack will use the module's SPI interface to send LoRa packets formatted according to LoRaWAN specifications, which can then be received by any standard LoRaWAN gateway and forwarded to network servers like The Things Network or ChirpStack.
