I was reading https://en.wikipedia.org/wiki/STM32#Discovery_boards about the different models of STM32 Discovery boards when I read this:
“The following Discovery evaluation boards are sold by STMicroelectronics to provide a quick and easy way for engineers to evaluate their microcontroller chips. These kits are available from various distributors for less than US$20. The STMicroelectronics evaluation product licence agreement forbids their use in any production system or any product that is offered for sale.”
so I looked it up and found
What are your thoughts on this?
