Today I ordered some component samples from Microchip!
Many component companies offer free samples.
Microchip is very friendly for sample orders. Others like TI may request that you buy the parts.
I ordered a ATTINY84A-PU and a MCP2221A from Microchip.
Sample orders are for prototyping and are not to be resold.
In many cases, email domains like gmail.com and yahoo.com are not accepted.
You may get lucky though. :)
If you want, you can attempt to order component samples from Microchip at this link:
(Make sure you have the complete part number.)
Please don't abuse component samples.
