EC-01 NB-IoT Module with UART 5G AT Commands TCP/MQTT/HTTP

NB-IoT (NarrowBand-Internet of Things) controlled via serial AT commands, supports communication protocols like LWM2M/COAP/MQTT, etc. Due to the advantages of low delay, low power, low cost, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, and so on. Onboard USB interface, for power supply OR debugging Breakout UART control pins, to connect with host boards like Uno/STM32 Onboard voltage translator, 3.3V by default, easy to monitor the working status Baudrate: 300bps~921600bps (115200bps by default) Control via AT commands (V.25TER, 3GPP TS 27.007, and AT Commands)
