When connecting via a web browser, we get presented with a list of applications that can be used.
One thing that must be kept in mind is that each application uses the FPGA in its own way, so you can’t run applications in parallel by opening multiple tabs in your web browser.
The first one that I tried is the signal generator, which I was able to plot by using my bench oscilloscope
The output is limited to +-1V as seen on this triangle generation:
There are no parameters to use in the web interface to change that, nor are there any jumpers on the board itself. If need be, it would be required to have external circuitry to shift/stretch the output voltage.
While fiddling around, one thing that struck me is the temperature the board is running at: it gets really hot!
Some components are reaching almost 60°C which is to be expected according to the documentation.
However, when manipulating the board, even only holding it by its sides, it’s easy to get a “burn” feeling that will make you drop it by pure reflex.
Here are a few pictures taken with a thermal camera, it’s quite uniformly hot on the sides.
And that makes me wonder how a PLA enclosure would behave in the long run. It may quite rapidly go runny like a camembert left on the outdoor table on a sunny day.
