I have been working on a project with an ESP32 and need help debugging my SPI connections. I figured a Logic Analyzer would be handy for this. After looking at several reviews and recommendations, I've narrowed it down to these 3:
1.
Saleae Logic 8This company seems to be the most recommended in forum threads, and have sigrok support. It's also closer to me physically and shipping might be easier in these times. But the device seems overpriced compared to the competitors. For my $199 (hobbyist price) i'd get 100Mhz sampling and none of the models have internal buffers.
2.
ASIX Sigma 2This is an interesting device. Its supported by sigrok, costs about $280 in the USA from its distributer (ucpros). It samples at 200Mhz, has a 256 MB internal buffer with hardware compression. On the downside, it's a little more expensive, and doesnt seem to have much info available online.
3.
DS Logic PlusFor my $150 I'd get a 400Mhz sample rate, and a 250mb buffer (cant find information on their compression technology, if any). On the flipside, I cant find a US distributer and might have to ship it from overseas (which isnt fun in a pandemic)
EDIT: potentially this is $70 on
Aliexpress On paper it would seem like DS Logic would be the best candidate, followed by the bit over my budget (~$200) ASIX Sigma. But I might be missing something or completely wrong about something.
I dont own an oscilloscope, so I figured investing in a half decent LA would be worth it.
