WiFi 6 = 802.11ax
earlier versions: 802.11ac, 802.11a/g/b/n
dual band: 2.4GHz and 5GHz
Wifi 6 does NOT imply 5GHz
Prototyping Electronic Circuits
Three types of boards. All use square grid of 0.1 inches (2.54 mm) spacing to accomodate DIP chips.
perfboard - holes, each hole surrounded by with square or round solder pad
stripboard - holes and strips, aka Veroboard
breadboard - solderless holes and strips, aka protoboard
stacking with standoffs
