Data transmission wireless module SLM130

MeiG Smart SLM130, SLM160 and SLM190 have the advantages of high performance, high reliability, low power consumption and wide voltage. SLM130 adopts Eigencomm EC616 platform, while SLM160 and SLM190 adopt EC616S platform, which support Release14, including features such as CAT-NB2, 2-Harq, OTDOA; It has Cortex-M3 core, with the highest frequency of 204MHz, built-in 4MB Flash, and sufficient memory; EC616 also supports 26 GPIO ports, 3 UART, 2 SPI, 2 I2C, 4 ADC, temperature sensor and battery voltage detection. The three modules are all designed with high integration, packaged in LCC, easy for mass production, compatible with market-related mainstream products, supporting ultra-wide voltage, ultra-low power consumption and ultra-high sensitivity, supporting China Mobile OneNET, China Telecom, Huawei OceanConnect, Alibaba Cloud and other open platforms of Internet of Things. They support domestic full Netcom frequency band, and have network service protocol stack for convenient application, support low-voltage power supply (2.2V~4.5V), built-in eSIM card location, low-power and power-saving design, which can meet the application requirements of most Internet of Things products, including smart water meters, smart gas meters, smart parking, smart detector, smart cities, shared equipment, security, asset tracking, smart home appliances, wearable devices, agriculture and environmental monitoring and many other industries. Regarding the access network, the uplink transmission scheme of NB-IoT supports single-tone transmission and multi-tone transmission. Single tone scheme supports better coverage, capacity and terminal power consumption;
