BLE Carbon 96Boards IoT Edition Board Runs Zephyr OS

Linaro Connect Las Vegas 2016 is taking place right now, and the organization has some very interesting development, with a new focus on the Internet of Things thanks to the creation of LITE (Linaro IoT and Embedded) segment group that will work on “delivering end to end open source reference software for more secure connected products, ranging from sensors and connected controllers to smart devices and gateways, for the industrial and consumer markets”. The first LITE IoT Reference Platform release to be made in December 2016, but in the meantime, Linaro introduced 96Board IoT specifications, as well as the first compliant board with the launch of Carbon board (aka BLE Carbon) running Zephyr OS. Carbon 96Boards IoT Edition board specifications: MCU – STMicro STM32F401 ARM Cortex M4 microcontroller @ up to 84 MHz with 512kB Flash, 96kB ram Connectivity – Bluetooth 4.0 LE via Nordic Semi nRF51822 SoC + chip […]

Marvell ESPRESSOBin Board with Gigabit Ethernet, SATA, mini PCIe, and USB 3.0 To Launch for $39 and Up (Crowdfunding)

I can often read people hoping for an inexpensive community board for network, storage and connectivity applications with high speed interface like SATA, multiple Gigabit Ethernet port, USB 3.0 and/or mini PCIe, and that’s exactly what Globalscale Technologies is about to offer with their Marvell ARMADA 3700 based ESPRESSOBin development board to go for $39 and up via Kickstarter.

$16 and Up RGB LED Bluetooth 4.0 Light Bulbs include Speakers

I’ve just stumbled upon “H1007 Smart E27 Bulb Bluetooth 4.0 Speaker” on GeekBuying. It’s a smart Bluetooth 4.0 RGB LED E27 light bulb that also include a speaker, and sells for $22.59 shipped. I find it’s a good idea, and after looking for other models, I’ve found the $99 Twist light, as well as a much cheaper “OY-QP-BM13” model on eBay going for $15.99. I’ll look at (HZ-)H1007 specifications first: Light Bulb 5W; adjustable RGBW; 330 Lumens; Color temp: 6500K Screw Type – E27/E26 Connectivity – Bluetooth 4.0 LE up to 20 meters range Audio – 3W amplifier; 3D surround audio Voltage – 100 to 240V 50/60Hz Dimensions – 72 mm diameter x 136 mm length Weight – 146 grams The body of the light bulb is available in white, red, golden, and blue, and it ships with a user’s manual in English and Chinese. I could not find the […]

Sonoff TH10/16 WiFi Relays Support Temperature and Humidity Probes

Sonoff are dirt cheap WiFi AC/DC relay systems based on ESP8266 selling for about $5 with board and case. They are made by ITEAD Studio, and the company has now new versions supporting up to 16A @ 250V, and with a 2.5mm connector to connect external temperature and humidity probes. Two models are available Sonoff-TH10 (10A max) and Sonoff-TH16 (16A max) with the following specifications: SoC – Espressif ESP8266 Tensila L106 32-bit MCU up to 80/160 MHz with WiFi Connectivity – 802.11 b/g/n WiFi with WPA/WPA2 support Relay Sonoff-TH10 – HK3FF-DC5V-SHG supporting 90 to 250 VAC input, up to 10A (2200 Watts) Sonoff-TH16 – Hongfa HF152F-T supporting 90 to 250 VAC input, up to 16A (3500 Watts) Terminals – 6 terminal for mains and load’s ground, live and neutral signals. Misc – 4-pin 2.5mm jack for external probes, LEDs for power and WiFi status Dimensions – PCB: 89.1 x 45.0 […]

Broadlink MP1 Quad Socket WiFi Power Strip Review and Teardown

Broadlink MP1 is an inexpensive ($20) power strip with four international sockets that can be controlled over WiFi. Since I was interested in finding out how the power strip was designed internally, I asked GearBest whether they could send a sample for evaluation, which they did, and I got it today. So I’ll first check the device, and hardware design, before trying it with the Android app. Broadlink MP1 Unboxing I don’t have much to say about the package, it’s just a bland white box with Broadlink logo. The bottom of the package is useful however, as it contains a sort of user guide in Chinese together with the specifications. I could not find any mentions of CE/FCC/CCC (for WiFi) or UL/TUV (safety) certifications on the package. There’s no more information inside the box, except what looks like a warranty card in Chinese. The power strip itself has four multi-standard […]

Widora-NEO OpenWrt WiFi IoT & Audio Board is Based on Mediatek MT7688 SoC, WM8960 Audio DAC

A couple of weeks ago, I reviewed ReSpeaker board combining MediaTek MT7688 WiFi SoC with WM8960 audio DAC, running OpenWrt, and allowing you to perform tasks using text-to-speech and speech-to-text thanks to the built-in microphone (or optional microphone array), and a 3.5mm audio jack to connect speakers, as well as several I/O pins. It turns out there’s been board with similar features, minus the built-in microphone, available in China for a while. Meet Widora-NEO. Widora-NEO board specifications: SoC – Mediatek MT7688AN MIPS SoC @ 580 MHz with built-in WiFi System Memory – 128 MB RAM Storage – 16MB SPI flash, micro SD card Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi 1T1R up to 150 Mbps with PCB antenna, or IPEX connector Audio – 3.5mm jack for stereo headphone and mono microphone, WM8960G audio codec USB – 1x micro USB port for programming via CP2104 chip, 1x micro USB host (or […]

Pine64 Unveils $2 PADI IoT Stamp WiFi IoT Module with FreeRTOS SDK, Upcoming ARM mbed 5.0 Support

Realtek RTL8710 WiFi IoT modules came out as potential competitors to ESP8266 modules last month, with similar features. an ARM Cortex M3, and a pricing as low as $2 in quantities. However, documentation is often in Chinese only, and based on my experience with an RTL8710AF module limited to AT commands set for now. Software and documentation are likely to improve a lot however, as Pine64, the makers of Pine A64 boards, are about to launch their own “PADI IoT Stamp” RTL8710AF module for just $1.99 in any quantities. PADI IoT Stamp specifications: SoC – Realtek RTL8710AF ARM Cortex-M3 @ 83 MHz with 1MB ROM, 512KB RAM, and 1MB flash Connectivity – 802.11 b/g/n WiFi @ 2.4 GHz – 2.5 GHz (2400 MHz – 2483.5 MHz) with PCB antenna; Station / SoftAP / SoftAP + Station modes; Expansion headers – 22 half-holes with Up to 1x SPI @ 41.5 Mbps […]

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 & […]
