Particle E-Series Modules – LTE Connectivity designed for IoT

Building an Internet of Things based system has always been an exciting art that usually comes with one major challenge to overcome – Connectivity. A smart system or an even intelligent system that collects data without having any network capability can’t be called an IoT system and it’s that device connectivity that gives it the IoT factor. Cellular connectivity has been one of the go-to connectivity for IoT system, and 2G networks have been the umbrella for this connectivity option mostly because it is virtually available everywhere.

Particle IoT 4G ESeries LTE

Despite the success that 2G & 3G networks have brought to the adoption of Internet of Things application, they are also slowly being phased out for the more robust, better 4G networks. Countries like Australia have stopped a nationwide use of 2G networks and some other countries already making plans to do the same. Particle, a developer of networking hardware and software for connected devices that has released several IoT focused boards in the past, like the Particle Photon and Particle Cellular Modules, has recently launched new LTE modules for 4G networks. These new devices aim those people whose devices depend on 2G and 3G networks and comes with a cloud and SIM support.

The LTE modules are part of Particle’s existing E Series suite, which comes bundled with the Particle Device Cloud, Device OS, and Particle’s collection of developer tools. The E Series modules are powered by an STM32F205 ARM Cortex M3 microcontroller running at 120MHz with features a 1MB Flash, 256KB RAM, and a wealth of GPIO. The modules integrate the industry-leading u-blox Sara cellular modems that provide support for 2G, 3G, and LTE M1/NB1 radios.

The LTE E Series modules are build on their famous Electron cellular prototyping kit, and they all come with standard wireless and cellular certifications – PTCRB Certified, FCC/CE/IC/GCF Certified, and RoHS Compliant. Also, they offer an extended operating temperature range from -20 to 85C for hostile environments. The modules come in 3 family types as listed below:

  • Electron development kit
  • E Series evaluation board
  • E Series modules

Particle Mesh – A Mesh-Enabled IoT Development Kits.

Particle, which has been known for its collection of  IoT focused development boards, and its Internet of Things (IoT) platform (Particle Cloud) has launched a new set of mesh network-enabled IoT development kits called Particle Mesh. Particle Mesh is expected to provide developers more insight into implementing mesh networking technology. They help to collect sensor data, exchange local messages, and share their connection to the cloud.

Particle Mesh features a new family of mesh-ready devices with Wi-Fi, BLE and LTE connectivity and also integrated with the Particle device cloud. Particle mesh consists of three main boards: The Argon, The Boron, and the Xenon. Each of these Particle Mesh boards has at least one form of outside connectivity option (LTE/3G/2G, Wi-Fi or Bluetooth) and an onboard mesh network hardware to facilitate setting up a mesh network for local communications between sensors and other particle mesh boards. All three devices are built around the Nordic nRF52840 MCU + BLE + mesh radio and follow the Adafruit Feather specification making it compatible with most Adafruit FeatherWing hardware accessories.

Open-Source NB-IoT Shield for Arduino

This completely open-source LTE shield uses the latest and greatest CAT-M NB-IoT technology optimized for low-power IoT devices! by Timothy Woo @ hackster.io:

With the emergence of low-power IoT devices with cellular connectivity and the phase-out of 2G (with only T-mobile supporting 2G/GSM until 2020), everything is moving toward LTE and this has left many people scrambling to find better solutions. However, this has also left many hobbyists facepalming with legacy 2G technology like the SIM800-series modules from SIMCOM. Although these 2G and 3G modules are a great starting point, it’s time to move forward and SIMCOM recently announced their new SIM7000A LTE CAT-M module at a developer’s conference. How exciting! 🙂

“In addition to WiFi, BLE, LoRa and Sigfox, we’ve added the latest cellular technology for IoT: LTE-M. But, we didn’t just go for one frequency type either. Nope, we partnered with the leaders in their field, Sequans, and are now proud to confirm that our module will have both CAT NB1 and CAT M1.”

The board specifications

  • ESP32-based – Espressif ESP32 SoC
  • Dual processor and WiFi+Bluetooth radio system on chip
  • Supports 5 networks: WiFi, BLE, cellular LTE-CATM1/M2(NBIoT), LoRa, and Sigfox
  • RTC running @ 32KHz
  • Size: 55 x 20 x 3.5 mm
  • Micropython enabled
  • Pymakr and Pymate compatible
  • All your apps from WiPy, LoPy and SiPy will work on FiPy too
  • Open source firmware

Pycom is redefining IoT with this brand new module! FiPy gives access to all the world’s LPWAN networks on one tiny board. It is now live on Kickstarter, check the campaign video:

You can pre-order your FiPy now for $39, the campaign still has 23 days to go and it has already achieved double of its goal. More information about FiPy plus its sensors and accessories check the crowdfunding campaign and the official website.
