I’ve made lots of small steps on the A3PN250 FPGA breakout board the last two weeks. Firstly, I built an JTAG adapter cable to work around a wiring error on the PCB. When I laid out the board, I accidentally … Continue reading
I’ve recovered from the busy last few months and that means I can spend a little more time at my workbench. The first of the A3PN250 (ProASIC3 nano) FPGA breakout boards is built. Here it is, in all its glory:
After a busy week spent traveling for work and a morning digging out from a surprise snowstorm, I had a great weekend with my family. It was Sunday night before I heated up the soldering iron and got down to business building the ProASIC 3 nano FPGA board.
I started with the toughest component, the FPGA. Its central location and low height means …. Continue reading
Here at last is the printed circuit board layout for the FPGA breakout board. I’m planning a series of projects involving FPGA-based DSP for ham radio, and in order to build them, I need an FPGA and a PCB on which to mount it….
The goals for this layout constrained it to be a nearly single-sided layout, … Continue reading
