The M66 is a quad-band GSM/GPRS 2G module measuring 17.7mm × 15.8mm × 2.3mm which uses LCC castellation packaging. Based on the latest 2G chipset, it is optimized for data, SMS and audio transmission, and is designed for low-power IoT use cases that operate in harsh conditions. The M66 uses surface mounted technology, making it ideal for large-scale manufacturing, which can have strict requirements on cost and efficiency. The M66’s ultra-compact profile makes it particularly suited to size-sensitive applications, and the module can serve a range of applications such as wearable devices, automotive, PDAs, asset tracking, POS, smart metering and telematics. Key features Supports frequency bands 850/900/1800/1900MHz Easier soldering process with LCC package Power consumption as low as 1.3mA Supports QuecFOTA Supports Quectel OpenCPU Embedded internet service protocols, multiple sockets and IP addresses
