Introduction to Developing a New Wireless Product

https://blog.hackster.io/introduction-to-developing-a-new-wireless-product-bf0a6c5b51a4#.esxyeyiei There are two routes to incorporating wireless functionality into a custom PCB design: a self-contained module, or a chip design. In almost all cases, it’s best to start off with a module solution. Wireless functions can be one of the trickiest types of circuits to design so modules are very commonly used.

A finger presents an impedance of approximately 100 pF in series with approximately 100Ω to ground, and this condition loads and modifies oscillations”

From I2C to I3C

The MIPI Alliance Inc. industry consortium has just released the specification for the Improved Inter-Integrated Circuit – or I3C – a sensor interface specification. The I3C is supersets the I2C specification. I3C is aimed to streamline sensor integration in smartphones, wearables, Internet of Things (IoT) devices and automotive systems. I2C has been the most widely

Debugging mechanism in Intel CPUs allows seizing control via USB port

https://www.scmagazine.com/debugging-mechanism-in-intel-cpus-allows-seizing-control-via-usb-port/article/630480/ Some Intel CPUs have JTAG over USB 3 debugging built-in. This could be good for debugging but is really bad for computer security. “starting with the Skylake processor family in 2015, Intel introduced the Direct Connect Interface (DCI) which provides access to the JTAG debugging interface via common USB 3.0 ports.” Having the DCI
