prototyping - When to avoid using a breadboard


What are the cases where one should avoid using a breadboard? e.g. high frequency, noise prone circuits etc.



Answer



Areas where the common breadboard does poorly:



  • High voltage

  • High frequency (above 10MHz)

  • Where the additional breadboard capacitance would present problems (oscillators, etc)

  • Where glitches due to poor wire connections would result in poor operation

  • Where most of the parts are not through hole 0.1" (2.54mm) centers


  • For anything but on-the-bench prototyping (ie, don't take it out of the lab and expect it to work)

  • Sensitive analog electronics, such as sensor usage

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
