Wire gauge of 40 pin IDE cable


What is the gauge of wire used in a typical commercial 40 pin IDE cable?

Answer



26 or 28 AWG for typical ribbon cables (like the one in the O.P. picture). Ribbons with bigger wires (smaller AWG) are more of a specialty. Here's a datasheet for your generic ribbon cable, which specifies the wire gauge (bottom of the page).


P.S. Of course, if one wire in the ribbon can't carry enough current, you could use several in parallel.

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...
