There are many LQFP breakout boards available on the market today. An example can be found here. I was curious as to their effectiveness in prototyping microcontrollers. I'm speaking of building circuits that will allow for basic programming of the chip, and nothing more. My main concern is that higher frequency clock signals may become distorted if ran through a breadboard. Thank you in advance!

  • \$\begingroup\$ @mattyoung i want to learn how to design microcontroller circuits. Bypassing this step does not help. \$\endgroup\$ – tuskiomi Dec 18 '16 at 2:33
  • \$\begingroup\$ And how do you think it helps? Microcontroller circuits are not hard to design. They generally require the micro and some caps, with requirements defined in the datasheet. That's a pretty pointless thing to prototype. \$\endgroup\$ – Matt Young Dec 18 '16 at 2:35
  • \$\begingroup\$ @mattyoung i mean, not learning this is shooting myself in the foot. I have to learn the basics before moving onto advanced things. \$\endgroup\$ – tuskiomi Dec 18 '16 at 2:37

    \$\begingroup\$ I don't think these provide a lot of learning potential. The main purpose used to be a cheap way to get something to try out software or peripheral control an MCU when dev boards were expensive. It isn't really a useful stepping stone between working with premade dev. boards and building your own custom MCU board. If you want to design your own, buy a dev board, examine it and the schematic, and then start drawing your own. \$\endgroup\$ – Evan Dec 18 '16 at 3:54
