Banana Pi M2 Ultra Allwinner R40 Development Board with SATA & GbE Sells for $46

Allwinner A10 and A20 processors have been quite popular in the past since they could handle Fast or Gigabit Ethernet and SATA natively, included decent multimedia capabilities, and were found in low-cost hardware such as Cubieboard 2 or MeLE A1000. Since then we’ve had a few boards with SATA using newer and faster processors without SATA IP, meaning it was usually implemented using a USB 2.0 to SATA bridge leading to mediocre to average performance depending on the implementation and selected bridge. Allwinner R40 is the successor of Allwinner R20 with a faster quad-core Cortex A7 processor, but keeping Gigabit Ethernet, SATA, and most features of its predecessor. The good news is that Banana Pi has now launched the promised M2 Ultra development board based on the new processor for $45.80 + shipping on Aliexpress (Total for me: $48.35). Banana Pi M2 Ultra specifications: SoC – Allwinner R40 quad-core ARM […]

Meet Body Heat Powered MATRIX PowerWatch, The Activity Tracker You Never Need to Charge (Crowdfunding)

There are currently several issues with wearables that makes it sub-optimal devices, from displays that can’t be always-on, to unreliable sensors, and in my experience pretty poor reliability, as I’ve managed to go through 4 fitness trackers / smartwatches in a year. Another issue is that contrary to typical watches lasting 10 years with a coin cell battery, most wearables require to be charge every few days, weeks, with the very best devices being chargers every few months. MATRIX PowerWatch promises to solve latter, as you will never need to ever charge it since it charges itself by harvesting energy using your body heat. The company promotes it as a smartwatch, but it’s closer to an activity tracker, since you can’t keep the Bluetooth LE connection all the time in order to receive notifications to your smartphone. It’s basically used to show time, track your activity and sleep patterns, and […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]

$2 Wisol SFM10R1 & SFM10R2 Sigfox Modules and Evaluation Board

LoRa appears to be one of the most popular long range lower power WAN standards, at least based on the number of hobbyist boards coming to market, but hardware is not exactly cheap with modules such as Microchip RN2483 & RN2903 LoRa modules selling a little over $10, and development board such as LoPy normally going for at least $35. If large scale IoT is ever going to take off, prices will have to go lower, and AFAIK we are still waiting for the promised sub $2 Weightless chips. But if Elettronica In tweet is to be believed some Sigfox modules made by Korean company Wisol are selling for just $2, likely in larger quantities. WiSOL SFM10R1 is made with RCZ1 (Radio Configuration Zone 1 – ETSI – Europe), while SFM10R2 module is made for RCZ2 ((Radio Configuration Zone 2 – FCC – North America). SFM10R1 key features and specifications: […]

iv-Robotics Brings SMT Resistors, Capacitors, LEDs to Breadboards (Crowdfunding)

Most people will prototype electronics projects using a breadboard and typical axial resistors and “legged” capacitors & LEDs. This works reasonably well but can be messy, and you need to learn resistor codes to choose the right value. To reduce the number of legs and make it easier for beginner, iv-Robotics has decided to create small boards with SMT resistors, capacitors and LEDs instead with markings to solve those small issues. The company calls those iResistor, iCapacitor and iLed components, and offers them in boxes of 50 pieces with various values. Experienced users might also like the fact this it’s easier to store compare to traditional components, but I feel this is really a good idea for education, and kids getting started with electronics. The project is now on Kickstarter, where you can get 50 pieces for $10, 4 boxes of 50 pieces for $35, 8 boxes with iResistors and […]
