I have a MCP3008 - 8-Channel 10-Bit ADC mounted on my breadboard but I am trying to downsize my prototype. Do I need to have the ADC on a breadboard or can I just use female jumpers to attach it to the GPIO pins and just have it hang there.

What you suggest will work but is likely to be unreliable.

I may be corrected by the electronics guys but I would suggest the following reliability order.

  1. most reliable, ADC soldered into a custom PCB together with the other components and soldered connections between the Pi and PCB.
  2. reasonably reliable, ADC inserted into a breadboard with the other components and jumper wire connections between the Pi and PCB.
  3. least reliable, ADC and components and Pi connected with jumper wires.

If you go route 3 I would solder all the connections and glue or otherwise mechanically attach the components to a rigid base (to minimise stresses caused by flexing).

  • Thanks this is exactly what I was looking for. Do you have any suggestions for downsizing a project? – Arachnid Hivemind May 15 '17 at 13:14

    I can't help with that. I'm pretty much a breadboard person. – joan May 15 '17 at 13:19
