Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

Description

The NB-IoT-DevKit from Olimex is an IoT board with BC-66 LTE GSM module covering all worldwide GSM bands. The board includes a built-in LiPo battery port and charging circuit, Nano SIM holder, level shifters, status LEDs and a micro-USB connector.

NB-IoT (Narrowband Internet of Things) technology is a direct competitor to LoRaWAN and SigFox and has a few advantages:

• Higher speed 25.5 kbps up and downlink
• Single GSM cell can connect to up to 100 000 NB-IoT nodes
• Single GSM cell can cover up to 10-100km rural and 1-10km urban distance
• Can work up to 10 years on a Lithium 3V battery if less than 200 bytes are sent per day

Note: All GSM cells which work with LTE can also support NB-IoT, but this requires new protocol installation and licensee fee, so not all operators provide it by default. You have to check with your local GSM operator if they offer NB-IoT. Also, the SIM card must have this protocol enabled. SIMs with LTE may or may not work with NB-IoT, this depends on your operator.
