Exen Proto Arduino Compatible Board is based on Microchip SAMD21 MCU (Crowdfunding)

Nerdonic launched Exen Mini last year as the world’s smallest 32-bit Arduino compatible board, and getting the smallest board possible is very good for some projects, but so not much for other as Exen Mini is limited to just 8 I/O pins. So the company made another larger board called Exen Proto based on the same Microchip SAMD21 Cortex M0+ microcontroller, but offering more I/Os. Exen Proto specifications with difference against Exen Mini highlighted in bold: MCU – Microchip SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 12-pin 2.54mm pitch headers Up to 20x digital I/O Up to 19x PWM Up to 11x analog (ADC) up to 12-bit resolution 2x UART Up to 5x I2C 1x reset Limits – 3.3V, 7mA USB – 1x micro USB port Programming – Via micro USB port or SWD header Misc – Power LED, user LED, button […]

20-Hour Free Blockchain Training Course from the Linux Foundation

If we believe all the talk on the internet, blockchain technology will change the future by offering an ultra secure way to store all sort of data, and as we’ve seen with the IOTA tangle previously, it should impact all types of sectors and applications including the Internet of Things. So even if it is still early it might be worth learning more about the technology, and the Linux Foundation, which normally offers course from a few hundred dollars to several thousands dollars, is also offering a free blockchain training course entitled “Blockchain: Understanding Its Uses and Implications“. You’ll get 20 hours of video content and transcript, and can learn on demand at your own pace. Course outline: Chapter 1. Introduction to Blockchain – This section covers some of the technical aspects that comprise a blockchain and explain why blockchain is different and “works” in comparison with technologies of the […]

TS80 USB type-C Soldering Iron Up for Sale for $79.99

TS100 digital programmable soldering iron has been popular in recent years due to its compact size, open source STM32 firmware, fast heating, and it does the job. Another advantage is that the soldering can be powered by a standard 19V laptop power supply. As noted in a post about a separate soldering pen board with audio jack, the company behind TS100 has been working on a new model called TS80 powered via USB type C port, lighter & more compact, and supporting soldering tips that connect through a typical 3.5mm audio jack. The good news is that TS80 is now available for $89.99 on Sainsmart under the ToolPAC brand. Use TS80 coupon for $10 discount. [Update: TS80 is now sold on Banggood for $72.99 shipped] TS80 SUB type-C soldering iron specifications: MCU – STMicro STM32F103T8 Arm Cortex-M3 MCU @ 72 MHz with 20KB SRAM, 64KB or 128KB flash Temperature Range […]

Wavlink AC600 Waterproof WiFi Repeater & Router Claims up to 2 km Range

WiFi is used indoors in most cases, but if you are a service provider, or own property with a park or beach, you may want to extend your WiFi coverage outdoors. The only problem is that more routers are not designed to be placed outdoors, and it’s not always easy to protect them from raining, humidity or even sunlight. So ideally in those case, you’d want a weatherproof / waterproof WiFi repeater or touter, and one of those is Wavlink AC600 dual band AC repeater / router which I first found on Banggood for $69.99.Wavlink WL-WN570HA1 AC600 router specifications: Connectivity WiFI Dual band 802.11 a/b/g/n/ac WiFi up to ~600 Mbps: 150Mbps @ 2.4 GHz, 433Mbps @ 5 Ghz Encryption mode – WPA-PSK/WPA2-PSK Transmission distance – 2km Max Functions – WDS & WPS (No VPN) “Up to 1000 mW of power and enhanced receiver design” Ethernet – Waterproof 10/100Mbps Ethernet port (RJ45) Misc – 3x LEDs for signal strength indication Power Supply – […]

ClearFog GT 8K is a High-End Networking SBC Powered by Marvell ARMADA A8040 Processor

A few years ago, SolidRun launched ClearFog Pro and Base router boards based on Marvell ARMADA 388 Armv7 (32-bit) processor, and about a year later, the company introduced MACCHIATObin networking board powered by a more powerful Marvell ARMADA 8040 quad core Cortex A72 processor. The company has now given an upgraded to its ClearFog family with ClearFog GT 8K networking board powered on the same ARMADA A8040 processor as on the community board, and offering support for up to 16GB RAM, 6 network interfaces including one 10GbE SFP+ cage , and three mPCIe slots.

Amlogic A311D Media Processor Features Cortex A73/A53 Cores, an Arm Mali-G52 MP4 GPU

As far as processors are concerned, it’s been pretty quiet in the TV box space in this year with for example, devices based on Amlogic S922 yet to launch, and new TV boxes are normally launched with processors such as Amlogic S905X/Z/W or S912, as well as Rockchip RK3328 or RK3229. But this morning, I’ve been informed that Amlogic is working on a more powerful media processor based on info from buildroot release notes Amlogic A311D is an hexa-core processor featuring four Arm Cortex A73 cores, two Cortex A53 cores, and an Arm Mali-G52-MP4 GPU. Amlogic A311D specifications known so far: CPU – 4x Arm Cortex A73 @ TBD GHz, 2x Arm Cortex A53 GPU – Arm Mali-G52 MP4 Memory I/F – DDR3/4; LPDDR3/4 Storage I/F – eMMC, SD/SDHC/SDXC Video Output – HDMI Tx up to 4K2K @ 60 Hz with CEC & HDR support, CVBS Video Processing Unit (VPU) […]

Want Long WiFi Range? This $10 Directional Antenna Should Help

A typical WiFi router range is limited to around 50 meters, and even less in a building with walls and competing WiFi routers. But it’s also possible to use WiFi for longer range communication, and for example, CNLohr managed to get an ESP8266 module answering ping requests over 4km away with a powerful antenna that is supposed to allow for up to 20km range and costs around $80 (NB-2G18 model). But if you’re budget is more limited, Banggood has started to sell a “10dB directional antenna” for $9.84 shipped. It is said to be for TTGO ESP32 board, but I don’t see why if would not work with other WIFI boards with a u.FL or SMA connector. Specifications listed for the antenna: Frequency – 2400~2500MHz S.W.R.: <=1.5 Antenna Gain – 10dbi Radiation – Directional antenna Polarization – Linear Impedance – 50 Ohm Wire distance – 1m Connector: IPEX The main cable features an SMA […]
