The u-blox SARA-R500E embedded eSIM lets IoT devices connect to cellular networks without the need for a separate SIM card and supporting hardware, thus saving board space.
The MAYA-W2 series from u-blox provide wireless connectivity with Wi-Fi 6, Bluetooth LE, and 802.15.4 radios.
Time equals power when transmitting data to and from NB-IoT and LTE-M devices. How you use communication protocols can affect power use.
The LENA-R8 and LARA-R6 modules from u-blox connect devices to LTE networks, helping to minimize the impact of 2G and 3G shutdowns.
