Arduino Due clone based on the Atmel SAM3X8E, KiCAD design

This project came up to test PCB design with KiCAD. Some Atmel SAM3X8E microprocessors were available, the same as one finds on the Arduino Due, and I got tired on the limitations of the free version of Eagle. So I

Breakout board for the DAC900E a 165 MSPS @ 10 Bit DAC

This breakout board helps me to interface my FPGA with the DAC900E from Texas Instruments. The DAC has 165 MSPS and 10 bits which is quite some speed. The combination FPGA and DAC opens up for experiments with digital signal

PCB tinning including VIA soldering

This is some method I found on the net for solving the problem of protecting the cooper of self produced PCBs. What is done is the PCB is tinned before parts are soldered on it. I discovered that this was
