CompareDescription
The M66 Mini DB is a compact and portable board designed specifically for breadboard. The main equipped modules are the M66 Mini DB series wireless communication modules. M66 Mini Development Board (MiniDB) can greatly assist you in experimenting, testing, designing, and generally speeding up the learning and product design processes, freeing your mind from getting bogged down with peripheral technical issues. This development board is designed for the M66 module from Quectel, allowing you to quickly set up the module and familiarize yourself with its capabilities. M66 is an ultra-small quad-band GSM/GPRS module using LCC castellation packaging. Based on the latest 2G chipset, it delivers optimal performance in SMS and data transmission and audio services even in harsh environments. Its ultra-compact profile (15.8 mm × 17.7 mm × 2.3 mm) makes it a perfect platform for size-sensitive applications.

Getting Started Preparation
- Step 1: Install Qnavigator software from https://www.quectel.com/download/qnavigator_v1-5/
- 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.
