Step 2: After installation Act like a software wizard.

Step 3: Connect the Development Board by USB to UART converter to the computer.(pin p1-3, p1-4)

(Download your driver type according to the USB-to-serial IC model)

Step 4: select your board in the port section, set the baudrate to 115200, and click Connect.

Step 5: Click on the gear and see if the module is connected.

Step 6: By entering AT Command, you can use different parts of the module.

Hint: make sure the power supply voltage is stable. The board to power up and turn on automatically without the need for a turn-off function.

FAQ #

What is the MC60 Mini DB?
+

A breadboard-friendly breakout board for the ultra-compact Quectel MC60 module — the world’s smallest Quad-band GSM/GPRS + GNSS + Bluetooth combo module.

Which cellular bands does it support?
+

Full Quad-Band 2G: 850 / 900 / 1800 / 1900 MHz — works worldwide on legacy 2G networks.

Does it have Bluetooth and GNSS?
+

Yes — Bluetooth 4.0 (onboard Johanson chip antenna) and full multi-constellation GNSS (GPS/GLONASS/BeiDou/Galileo/QZSS) with AlwaysLocate™ and GLP low-power modes.

How to power the board?
+

Connect 5 V to the +5 pin (P2-10). Onboard 2 A switching regulator converts it to the required 3.6–4.2 V. Peak current during GSM bursts can reach ~1.8 A.

Are external antennas required?
+

Bluetooth: Onboard chip antenna (no connector needed)
GSM & GNSS: Two U.FL connectors — external antennas strongly recommended for reliable operation

How many UARTs are available?
+

Three UARTs are exposed:
• Main AT UART (TX/RX)
• AUX UART (AUXTX/AUXRX)
• Debug UART (DBGTX/DBGRX)

Can I make voice calls?
+

Yes — differential MICP/MICN and SPKP/SPKN audio pins are available for headset or speakerphone connection.

How to send AT commands?
+

Use the main UART (P1-3 RX / P1-4 TX) at 115200 bps with any USB-to-UART adapter or use QNavigator tool from Quectel.

What are the board dimensions?
+

Compact breadboard-compatible size: 36.5 × 26.2 mm.

What do the LEDs indicate?
+

D1 (NETLIGHT): Network status (blinking = searching, fast blink = registered, slow blink = data)
D2: Power ON
