I’ve been trying for several weeks to purchase a Z2 or ZU board from TUL by emailing email@example.com, but I never get back a response. Has anyone else had this issue and/or do you suggest another way of purchasing a board? Thanks.
You may be able to find the PYNQ-Z2 in stock with other distributors. There are some links on the TUL website. There are shortages at the moment, so you may need to search around or wait for boards to become available.
E-elements.com ( a distributor for TUL) had 50 boards as of a couple of weeks ago.
