It’s hard to keep up with all the systems-on-module based on Arm Cortex-A “application class” processors, but so far I can’t remember seeing any Arm Cortex-M “microcontroller class” SoM. However, SoMLabs is currently working on VisionSOM-RT, a system-on-module based on NXP i.MX RT 1050 Arm Cortex-M7 processor clocked at 600 MHz. NXP i.MX RT series processors are actually promoted as a “crossover” processor delivering application processor performance with real-time capabilities right at the edge between the two classes of processors. VisionSOM-RT (SLS12Rx) module preliminary specifications: SoC- NXP i.MX RT Arm Cortex-M7 processor @ up to 600MHz with NXP PXP 2D graphics accelerator, and Graphics Engine PXP PiXel processing pipeline for imagine resize, rotation, overlay and color space conversion. Memory – 512kB on-chip RAM memory, up to 32MB SDRAM Storage – Up to 16MB QuadSPI flash, optional 4GB eMMC flash 200-pin SO-DIMM edge connector with Display Interface – 8/16/24-bit Parallel RGB […]
Tri-Panel Waterproof Solar Power Bank Sells for $25
A few years ago, I purchased a power bank with a solar panel, but it only came with a 1.5W panel, and I found it took around 10 to 20 days to charge the 8,000 / 10,000 mAh battery in sunny Thailand, allowing me to charge the phone 4 times. So the rate of charge was not quite enough for self-sufficiency, and while I placed the power bank on a roof outdoors, it was not ideal since it was not waterproof, and I forgot to remove it sometimes when it rained, but it still survived for over two years… Solar power bank are mostly useful if you go outdoors in places without electricity for a few days, or if you have a project that would benefit from being powered that way. Depending on your requirements, a faster rate of charge and waterproofness may be useful features to have and that’s […]
ODROID-N1 Canceled due to RAM Supply Issues, ODROID-N2 Coming Later this Year
Rockchip RK3399 powered by ODROID-N1 board was unveiled earlier this year with two SATA interfaces, up to 4GB RAM, HDMI 2.0 4K UHD output, Gigabit Ethernet, and more. The plan was to launch the board in May or June for around $100. Sadly, the board has been canceled for reasons we’ll explain below, but the silver lining is that a more powerful ODROID-N2 should become available by the end of the year. The reason for the cancellation is all explained in a forum post in ODROID forums: After announcing the N1 board in February, we started to prepare all the components for the mass production. But Samsung and Hynix suddenly informed us 1GB DDR3 chip was End-of-Life phase and we couldn’t place any order. It meant we could not make 4GB model since there must be four DRAM chips mounted on the board. We could make a 2GB model only […]
Tail it is a Family of WiFi & Cellular GPS Trackers for Things, Pets, and Bicycles (Crowdfunding)
We’ve previously written about Ping, a tiny Cellular GPS tracker that promised to last 3 months on a charge. The raising money part of the crowdfunding campaign itself was successfully with over one million dollars raised, but as with many such campaigns there have been delays, and some people still have to receive theirs, not to mention people complaining about poor battery life and other issues. But there seems to be another option now with Tail It Technologies now offering four different “Tail it” cellular GPS trackers (with WiFi too) for things, pets, and even one designed specifically for bicycles. The company has already sold their devices to thousands of customers in Norway, so they should be working, and on-time delivery should hopefully not be an issue. All four GPS trackers come with 2G, 3G, 4G, and WiFi connectivity, a 5-meter accuracy, and share the same electronics and firmware. Here’s […]
NoCAN IoT Platform Leverages Raspberry Pi & Arduino for CAN Bus Projects (Crowdfunding)
Many IoT projects rely on wireless connectivity through WiFi or Bluetooth, but in some cases it may be more reliable and convenient to use wired connectivity. The CAN Bus is a little like a low bandwidth Ethernet PoE solution for IoT, as it allows to transfer data over a serial connection while provided power at the same time, and can be daisy chain to support multiple boards. Omzlo’s NoCAN IoT platform provides a CAN bus solution leveraging Raspberry Pi 3 board through their PiMaster HAT acting as a CAN bus gateway, and Arduino compatible CANZERO boards to which you can connect sensors and actuators. Omzlo PiMaster HAT specifications: MCU – STMicro STM32F042 Cortex-M0 32bit ARM MCU – 48Mhz. Networking – 125000 bps CAN bus up to 300 meters range GPIO – Communicates with Raspberry Pi through SPI + GPIOs Security – Smart power switch with over-current protection. Power Supply – […]
RoKi Sensor Node Bluetooth 5 Devkit is Equipped with Multiple Sensors
ROHM and Kionix have just introduced the RoKi Sensor Node, part of the new RoKi IoT Platform. The sensor node is based on Nordic Semiconductor’s nRF52840 Bluetooth 5 LE System-on-Chip (SoC), and integrates multiple sensors from Kionix and ROHM. RoKi Sensor Node specifications: MCU – Nordic Semi nRF52840 Bluetooth 5 Arm Cortex M4F processor @ 64 Mhz with 1 MB flash, 256kB RAM Sensors Built-in 3-axis accelerometer Combination 3-axis accelerometer + 3-axis magnetometer Combination 3-axis accelerometer + 3-axis gyroscope 3-axis magnetometer Barometer Available with expansion connectors Optical heart rate sensor Ambient light sensor RGB color sensor Magnetic hall effect sensor etc Misc – Programmable RGB LED Power Supply – Rechargeable Li-Polymer battery, replaceable coin cell batteries, or via Micro USB.

WAHE Home is an Android Keyboard PC Powered by Rockchip RK3288 Processor
We’ve previously covered a couple of Android keyboard PCs in the past. First the ill-fated Coolship keyboard PC that never show the light of the day, and later on, Intel based dual boot Android + Windows 10 T20 keyboard computer. The latter sold at the time, but is no longer available. But in the unlikely case you are still looking for an Android keyboard PC, Rockchip RK3288 powered WAHE Home should soon become available. Wave Home specifications: SoC – Rockchip RK3288 quad core Cortex A17 processor with Mali-T760MP4 GPU System Memory – 2GB RAM Storage – 16 GB eMMC flash Video Output – HDMI 1.4 up to 4K @ 30 Hz Audio – Via HDMI, built-in speaker, 3.5mm audio jack Connectivity – Dual band 802.11 b/g/n WiFi, Bluetooth 4.0 User Input – Removable 83-keys QWERTY keyboard and touchpad USB – 3x USB 2.0 host ports Power Supply – Dimensions – […]
Firewalla is a Tiny Firewall Appliance Based on NanoPi NEO Board
FriendlyELEC Nanopi NEO and NEO2 boards are really cool and inexpensive little Arm Linux boards suitable for all sort of headless application. I’ve reviewed one with their NAS Kit, and run one around the clock as a Domoticz/MQTT server. So it should come as no surprise that some people want to leverage the hardware in their own products, and Firewalla most likely relies on a NanoPi NEO board for their cute firewall/parental control/VPN appliance.Firewalla specifications: SoC – Unnamed quad-core Arm processor @ 1.0 GHz System Memory – 512 Megabyte DDR RAM Storage – 16GB MicroSD Storage Connectivity – 100 Mbit Software Packet Processing Power – 5V via micro USB port Dimensions – 2.8 cm thick The device ships with a flat Ethernet cable, a USB power cable and US type power adapter, and a one year limited manufacturer warranty. The company does not actually mention NanoPi NEO board anywhere, but the specifications […]
