Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white.  Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast.  There was an in-depth article written on a similar hub some time ago.  Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is delivered to the unit by a locking Molex connector. Also, …

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) based on LPC54018 Arm Cortex-M4 core @ 180MHz with Longsys …

Detect Lightning with Those AMS AS3935 “Thunder” Boards

Launched in 2012, AMS AS3935 Franklin lightning sensor  is – at its name implies – a lightning sensing IC. The chip was designed for low power, portable or fixed wire-line applications, and beside detecting electrical emissions from lightning activity, it can also provide an estimation of the distance to the head of the storm from 40km away down to 1km, while filtering out other signals from motors, microwave ovens, etc… The chip interfaces via SPI or I2C to the host processor / micro-controller, and comes in a small MLPW-16 (4x4mm) package. Price is $3.55 per unit for 1k orders. Applications include wearables, golf carts, pool safety, portable GPS, bike computers, weather stations, uninterruptible power supplies, smart grid systems, environmental monitoring systems, etc… Basically, AS3935 can be used either for weather monitoring, or safety applications. I’ve found two maker boards with the chip: MikroElectronika Thunder Click board compatible with MikroBUS socket (available now), and SwitchDoc Labs Thunder Board recently launched on …
