The N11 is a 2G Quad-band GPRS module that has a UART interface for communication with the MCU via simple AT commands.
It supports the network protocols CoAP, MQTT, TCP, UDP, PING, FTP, HTTP, HTTPS, DNS, and PPP and is available in an LGA package of only 15.8x13.8mm.
Neoway, in turn, is launching its NBIoT N21 module, with a pin-to-pin format compatible with the N11 model, which gives us the possibility of creating an application with 2G GPRS communication, and being able to migrate to NBIoT in a simple way if necessary.
The NBIoT N21 module supports the European bands B3, B8, and B20 (the main band used in Spain). It features low power consumption of less than 4µA in PSM mode.
