The board to power up and turn on automatically without the need for a turn-off function. ## Resource Download - [schematic mc60 mini DB](https://eicut.com/wp-content/uploads/2025/10/schematic-mc60-mini-DB.pdf) - [footprint-MC60-mini-DB](https://eicut.com/wp-content/uploads/2025/10/MC60-mini-DB.zip) - [Quectel_MC60_GSM_Specification_V1.2](https://eicut.com/wp-content/uploads/2025/10/Quectel_MC60_GSM_Specification_V1.2.pdf) - [Quectel_MC60_Series_GNSS_Protocol_Specification_V1.1](https://eicut.com/wp-content/uploads/2025/10/Quectel_MC60_Series_GNSS_Protocol_Specification_V1.1.pdf) - [Quectel_MC60_Series_Hardware_Design_V2.0](https://eicut.com/wp-content/uploads/2025/10/Quectel_MC60_Series_Hardware_Design_V2.0.pdf) - [MC60 Firmware (MC60CAR01A15)](https://eicut.com/wp-content/uploads/2025/10/MC60CAR01A15.zip) ## 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 [![MC60 Mini Development Board Supporting Quad-band GSM/GPRS/GPS/GLONASS/QZSS/Bluetooth](https://eicut.com/wp-content/uploads/2025/10/Frame-34_11zon-273x300.webp)](https://eicut.com/product/mc60-mini-development-board)
