u-Blox Unveils SARA-R4 LTE Cat M1 and SARA-N2 NB-IoT Modules for Professional IoT Applications

While I’ve mostly read about SigFox and LoraWan solutions for long range, low power, and low bitrate communications for the Internet of Things so far, there are many active of planned LPWAN standards for IoT applications, and 3GPP Release 13 standard stipulates two LTE LPWAN standards, namely LTE Cat M1 (eMTC) and LTE Cat NB1 (NB-IoT), with the former supporting 1 Mbps downlink and uplink peak data rates, and the latter 250 Kbps downlink, and 250 Kbps (multi-tone) or 20 Kbps (single tone) uplink data rates. U-Blox has released modules for both standard with SARA-R4 LTE Cat M1 and SATA-N2 NB-IoT modules. SARA-N2 Cat NB1 cellular module specifications: LPWAN Connectivity – 3GPP Release 13 NB1; NB-IoT bands: 5, 8, 20; downlink: 227 Kbps, uplink: 21 Kbps Positioning – GNSS via Modem Interfaces – 1x UART, 1x SPI, 2x GPIO, 1x DDC(I2C) for GNSS Features – Antenna supervisor, embedded IPv4 & […]

Espressif ESP32 WiFi & Bluetooth SoC is Now Up For Sale for $2.85

Espressif ESP32 is one of the most awaited chip for IoT applications as it combines a dual core processor, WiFi, Bluetooth 4.0, and various I/Os. The good news is that you can now purchase ESP32 for 19 RMB ($2.85) on Taobao, or if you are not based in China, contact Espressif by email at sales [at] espressif.com. Availability is however limited, and the maximum order is now 5 pieces. ESP32 modules and boards, as opposed to just the SoC, are not quite ready right now, but should become available in a few weeks. ESP-WROOM-32 is the ESP32 module developed by Espressif, and NodeMCU is also working on an ESP32 board, so we’ll get more good news very soon. You can also find documentation, hardware and software resources on a Espressif ESP32 page , including a getting started guide, ESP32 SDK, ESP32 reference manual, ESP-WROOM-32 datasheet, and more. If you are […]

Getting Started with ReSpeaker WiFi IoT Board’s Audio Capabilities, Voice Recognition and Synthesis

ReSpeaker is a development board combining an Atmel AVR MCU, a MediaTek MT7688 WiFi module running OpenWrt, a built-in microphone, an audio jack, and I/O headers to allow for voice control and output for IoT applications. That means you could make your own Amazon Echo like device with the board and add-ons, use it as a voice controlled home automation gateway and more. The board was launched on Kickstarter a few days ago, and already raised $100,000 from about 100 backers, but I’ve received an early sample, so I’ll provide some more information about the firmware, and shows how to use with some Python scripts leveraging Microsoft Bing Speech API. You’ll need a micro USB to USB cable to connect your to computer (Linux, Windows, Mac OS…), and a speaker to connect to the board. Linux (OpenWrt) boots in a few seconds, and once it’s done all RGB LED will […]

Dot is a Location Aware Bluetooth Beacon Used as a Digital Post-it, for Home Automation, and More (Crowdfunding)

Dot physical push notification is another Bluetooth beacon, but the company – Iota Labs – has designed and promote it in a location aware device that gets triggered when you move in a specific area with your smartphone. For example, somebody can leave a dot with a message such as “remember to take the trash out” in the kitchen, and once you walk pass you’ll receive a notification, or you can use a dot to automatically turn on the light if you enter a room at night. The full technical specifications have not been made available but here’s what we know: MCU – Nordic Semi nRF51822 (or similar) ARM SoC with Bluetooth radio Connectivity – Bluetooth 4.0 LE with a range up to around 45 meters Misc – RGB LED Battery – Replaceable battery good for 6 months to one year Android and iOS apps will allow your to configure […]
