Hello, everyone I want purchase, for my laboratory, the component at surface mount (SMD), resistor and capacitor. The dimension that I need are: or 0805 or 0603. For the resistor I prefer the 1% tollerance. Where I can purchase that components in stock? There is any suggestion? As an indication how...

Yes, it should be unconnected on the nRF24L01. I should have checked the data sheet. A double-sided PCB will still be required. Unless you know what you are doing the Nordic RF layout should be adhered to meticulously. Leon It seems that the second layer in the layout in the datasheet is used only ...

Thanks, I didn't notice that in the datasheet.
Btw, the big pad under the IC is used only to dissipate heat right? Because if not, I'll have to go with a double layer pcb instead...

Routing tracks under the IC

So I'm designing a breakout for the nRF24L01 and I'm trying to fit it on a single layer pcb. I was wondering how wise/unwise is it to route some tracks under the IC? It has 3x VDD and 3x VSS pins on different sides, would it be ok just to route one to the VDD breakout pin and connect the other two t...

Too expensive. Wouldn't it be easier to buy old ball mice and strip them from there? Each has 2! :P
