I tried to buy a TDC7201-ZAX-EVM on ti.com/store, but I keep getting stuck near the end with the site rejecting my URL. This should be optional anyway, shouldn't it? I mean, does TI really not want to sell to individuals at all? Even ones who are writing open-source drivers to support TI chips?
There are probably two bugs here:
(1) Requiring a company/university URL at all, and
(2) Failing to accept a valid URL
These seem to be relatively recent problems, because I successfully bought an EVM a few years ago.
One workaround would be to just buy it from a distributor, but they charge more ($264.67 at Mouser and $229.62 at Arrow, versus $199 at TI).
