Communication

BC26

NB-IoT module used for low-power cellular sensor applications.

China-madeQuectelActiveModerate

Best For

Projects needing NB-IoT 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

BC26 is indexed as a communication part from Quectel. 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 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.

TX

Cross TX to RX between the module and controller.

RX

Check whether the module is 3.3V logic before connecting to 5V boards.

Arduino Example

void setup() {
  Serial.begin(115200);
  Serial.println("BC26 GPIO wiring smoke test");
}

void loop() {
  // Replace with the maintained BC26 library or module protocol.
  Serial.println("Read or toggle the connected signal pin.");
  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.
