$200 VOYO i8 Max 2-in-1 4G Android Tablet is Powered by Mediatek Helio X20 Processor

Mediatek Helio X20 (MT6797) deca-core processor was announced about 3 years ago, and made into various smartphones – such as Vernee Apollo Lite – as well as MediaTek X20 Android development board. However so far, I did not see any proper tablets based on the processor, but VOYO i8 Max tablet with a 10.1″ display and 4G LTE connectivity has just started to sell for $199.99 and up including shipping. [Update: price drops to US$162.99 with GKB89VW coupon. valid until 2018/7/24] Voyo i8 Max specifications: SoC – Mediatek Helio X20 deca-core processor with two Arm Cortex A72 cores @ 2.1 GHz, four Cortex A53 @ 1.95 GHz, four Cortex A53 @ 1.4 GHz, and Arm Mali-T880 GPU @ 800 MHz System Memory – 4GB RAM Storage – 64GB eMMC flash + micro SD slot up to 64/128GB Display – 10.1″ 1920×1200 IPS display with stylus support Audio – 3.5mm audio […]

Firefly AIO-3399J All-in-One Industrial Board is Powered by Rockchip RK3399 Processor, Supports M.2 SSDs, 4G LTE Modems, and More

Firefly-RK3399 was the very first Rockchip RK3399 development board when it launched in late 2016, and it mostly stayed that way until others joined in late 2017, early 2018 with products like Orange Pi RK3399, ODROID-N1, Rock960, or Pine64 RockPro64 among others. Firefly team has now unveiled another higher end “all-in-board industrial board” with their Firefly AIO-3399J board featuring their RK3399 CoreBoard module, and a baseboard exposing plenty of I/O and connector, including support for M.2 drives, and 4G LTE mini PCIe cards. Firefly AIO-3399J specifications: SoM – RK3399 CoreBoard: SoC – Rockchip RK3399 hexa-core big.LITTLE processor with dual core ARM Cortex A72 up to 2.0 GHz and quad core Cortex A53 processor, ARM Mali-T860 MP4 GPU with OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL and DX 11 support System Memory – 2GB or 4GB DDR3-1333 Storage – 16GB eMMC 5.1 flash (other capacities also available on demand up to […]

A Look at LoRaWAN and NB-IoT Power Consumption

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, […]

Turris MOX is a Modular Router with WiFi, SSD, LTE Modem, Ethernet, and SFP (Fiber) Modules (Crowdfunding)

The makers of Turris Omnia router – powered by a Marvell ARMADA 385 processor and running Turris OS based on OpenWrt – have been working a new product: Turris MOX modular router which can be extended with mPCIe add-on cards for LTE, SFP cage, M.2 SSD, and so on. They will soon launch an Indiegogo campaign for it, but in the meantimes, CZ.NIC association has a pre-campaign for a $69 MOX access point with dual band WiFI card, and intended for Turris Omnia users. The full details are not available, although we can find out a little more through root.cz and the video embedded below. The system is comprised of a basic MOX A module powered by a dual-core Armada 3720 processor coupled with 512 MB RAM, as well as USB 3.0, Gigabit Ethernet, and an I/O expansion header with GPIO, SDIO, UART and I2C. There’s also an mPCIe port […]

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 encourages pull requests, so manufacturers may consider updating it with their own boards. The list focuses on development boards acting as cellular IoT endpoints, 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. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, […]

Orange Pi 4G-IoT Development Board Launched for $45

Last year, Shenzhen Xunlong Software launched Orange Pi 2G-IoT board for just $9.90. Pricing was incredibly aggressive for a cellular board, but AFAIK the RDA Micro processor used in the design had never been used with Linux so for many people using the board was a challenge (and maybe still is), and some countries have already started to sunset 2G networks. So it only made sense for the company to work on a 4G board, and that’s exactly what they have done with Orange Pi 4G-IoT now launched for $45 + shipping on Aliexpress. Orange Pi 4G-IoT specifications: SoC – Mediatek MT6737 quad core Cortex A53 processor @ 1.1/1.3 GHz with Arm Mali-T720MP1 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash + micro SD slot Video Output – HDMI, LCD display interface with touch panel support Audio – 3.5mm earphone jack, built-in microphone Cellular Connectivity nano SIM […]

Rigado Vesta IoT Gateway Runs Linux and Zephyr OS, Supports Bluetooth 5, 802.15.4, WiFi, Ethernet and Cellular Connectivity

I’ve recently read several open source software news related to Rigado IoT gateway, starting with Canonical announcement last month, that the gateway would ship with Ubuntu Core starting in summer 2018, and a few days ago it popped up again during Linaro CEO keynote at Linaro Connect HK 2018, as one of the first commercial devices to run the Zephyr OS, specifically its fully open source Bluetooth stack on a Nordic nRF52 chip. Rigado Vesta IoT gateway is not exactly new, as it was first announced in December 2016. The hardware relies on an NXP i.MX 6UL Cortex A7 processor, up to 256MB RAM, 4GB eMMC flash, and includes built-in support for dual band WiFi, Bluetooth Smart, Bluetooth 5/4.2, 802.15.4 (Thread), Fast Ethernet with PoE, as well as optional support for a cellular LTE Cat 1 modem. Rigado gateway hardware specifications: Processor – NXP i.MX6 UltraLite (G3) Arm Cortex A7 […]

FOSSASIA Summit 2018 Schedule – March 22-25

FOSDEM is the “Free & Open Source Software Developers’ European Meeting” takes place the first week-end of February every year in Brussels, Belgium. It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in. I’ve […]
