“Best used with solid pin (jumper leads). Component legs (resistors LEDs etc) can be awkward to fit. A big plus is the availability of ready made dual supply (+3V3, +5V) modules to plug in at the breadboard end. This allows use of a bench power supply of +6 to +12V as main supply.”
“Words as expected, although as a breadboard noob I didn't realise that the power and ground rails didn't run all the way down. Note check the lines as they have a break half way down, where you will need to add a connecting wire.”
