Inexperienced circuit designers often consider the board layout for a switching regulator to be black magic. The most important rule is to design the traces, in which the current flow changes with ...

while simplifying the board design process. The integrated impedance-matching circuit technology presented by Renesas at ISSCC 2015 enabled compact and low-cost Bluetooth LE products that required no ...

In a previous episode of Hackaday, [Rich Olson] came up with a new no-etch circuit board fabrication method. And now, he’s put it to the test: building an nRF52 Bluetooth reference design ...
