Arduino Introduces Two New IoT Boards – MKR WiFi 1010 (ESP32) and MKR NB 1500 (NB-IoT + eMTC)

MKR-NB-1500

Arduino introduced its MKR family of breadboard compatible maker boards with MKR1000 featuring an Atmel SAMD21 microcontroller combined with a Microchip WINC1500 WiFi module. The board was followed by MRKZero without wireless connectivity,  then MKRFOX1200 Sigfox board, and finally MKR WAN 1300 & MKR GSM 1400 boards at the end of 2017 with LoRaWAN and 3.75G cellular connectivity. The company has now launched two new boards: Espressif ESP32 based MKR WiFi 1010 with WiFi and Bluetooth, and MKR NB 1500 equipped with an NB-IoT & LTE CAT M1 module.

A Look at LoRaWAN and NB-IoT Power Consumption

Battery-Life-LoRaWAN-vs-NB-IoT

LoRaWAN and NB-IoT are both designed for low power long range communication for the Internet of Things. We’ve previously seen both protocols have about the same 15km range in rural areas, and NB-IoT bitrate is a little higher since it can reach around 100 kbps, against 300 bps to 38.4 kbps for LoRaWAN. All LPWAN standards usually claim 10-year battery life, but it would be interesting to get some data about power consumption, and that’s exactly what AMIHO Technology has done by comparing LoRaWAN to cellular IoT (NB-IoT / eMTC) power consumption. They started by checking public information from datasheets, and compare Tx, Rx, Idle and Tx current for the three standards, and LoRaWAN is about three to five times more efficient in terms of current compared to NB-IoT, and as expected even more compared to LTE Cat-M1. They then went on to compare airtime for the different power states,  look at the energy comparison for a 50 byte payload, …

1NCE to Offer a 10 Euros Plan for 10-Year of Cellular IoT Connectivity in Europe

For the Internet of Things to be successful, prices need to come down sharply, and eventually LPWAN connectivity should be possible with $1 to $2 modules, $5 to $10 development boards like we can get for WiFi today. Cellular IoT hardware is likely to be a bit more expensive – even when using NB-IoT – but hardware prices have to come down to acceptable levels, and so is connectivity. 1NCE brings us in the right direction for the latter with a SIM card selling for 10 Euros offering 10-year of 2G/3G/NB-IoT connectivity (1 Euro per year) with 500MB data included.  That’s about 140KB of data per day, which should be OK for applications like smart meters. There are no other fees, except if your device goes over the limit,  but the company has not provided any pricing details for the extra data. The service will cover 30 countries in Europe. The SIM cards will start selling in August 2018, and …

A List of Cellular IoT Development Boards

We’re starting to have a decent choice of cellular development boards, and as the number of products is getting larger having some sort of list would be useful. That’s exactly what Hologram has done. While the list is not quite exhaustive, they’ve pushed the csv list to Github, and plans to update it. Hologram also encourage pull requests, so manufacturers may consider updating it with their own boards. The list focuses on development boards acting as cellular IoT end points, so you won’t find gateways, WiFi hotspots, end user devices and modules that needs to be soldered onto your own board. I have imported the list to WordPress to make it searchable, let people select the number of rows to display, and customize visible fields. The table is not automatically synchronized, so for the latest version always check out Github.

Nutaq PicoLTE IoT Kit Allows NB-IoT and LTE Cat M1 Devices Testing Anywhere

If you’ve been following cellular IoT news you must have read plenty of announced about NB-IoT and LTE Cat M1 (eMTC) hardware platforms bring LTE connectivity at lower power and somewhat lower cost than existing 3GPP networks. That’s all good, and you may have decided to go ahead with a commercial project, except none of the Telco are providing LTE IoT connectivity in your area just yet, or if it does, you may also want to test your device in bands not allowed/supported in your country (at a permitted power level). If that’s the case, Nutaq PicoLTE IoT Kit should help as an LTE NarrowBand & Cat M test measurement platform for IoT that can test NB-IoT and Cat-M1 devices in all frequency bands. Nutaq PICOLTE IoT kit key features: Supports M1 & NB-IoT devices Proven compatibility with M1 & NB-IoT devices from over 5 manufacturers Test multiple devices simultaneously (performance guaranteed up to 5 devices) Supports non-IP mode (NB-IoT) …
