Communication

SX1262

Newer LoRa transceiver used in long-range low-power radio modules.

China-madeSemtechActiveModerate

Best For

Projects needing LoRa and Low power with a commonly available communication part.

Avoid If

You need production-grade certainty without checking the exact module vendor, pinout, and library maintenance status.

Quick Decision Notes

SX1262 is indexed as a communication part from Semtech. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

VCC3.3VPower the module from a rail that matches the breakout board, not just the bare IC.
GNDCommon groundConnect ground between the controller, sensor/module, and external power supply.
SCKMCU SPI clockShare with other SPI devices when chip select lines are separate.
MOSIMCU SPI data outRequired for most displays, radios, and writable devices.
MISOMCU SPI data inMay be optional for write-only displays.
CSAny free GPIOUse one chip-select pin per SPI peripheral.

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

VCC

Power the module from a rail that matches the breakout board, not just the bare IC.

GND

Connect ground between the controller, sensor/module, and external power supply.

SCK

Share with other SPI devices when chip select lines are separate.

MOSI

Required for most displays, radios, and writable devices.

Arduino Example

#include <SPI.h>

const int chipSelect = 10;

void setup() {
  Serial.begin(115200);
  pinMode(chipSelect, OUTPUT);
  digitalWrite(chipSelect, HIGH);
  SPI.begin();
  Serial.println("SX1262 SPI wiring smoke test");
}

void loop() {
  // Replace this transaction with the maintained SX1262 driver call.
  digitalWrite(chipSelect, LOW);
  SPI.transfer(0x00);
  digitalWrite(chipSelect, HIGH);
  delay(1000);
}

MicroPython Example

MicroPython support is pending. Treat community scripts as prototypes until a maintained driver is linked and tested on a known development board.

Recommended Development Boards

ESP32-C3 development board

Low-cost Wi-Fi/BLE board with enough interfaces for most sensors and modules.

Arduino Uno R4 / compatible

Good baseline for beginner wiring and library validation.

Raspberry Pi Pico W

Practical MicroPython target for I2C, SPI, UART, PWM, and ADC experiments.
