Arduinos powered by AVRs aren't high-frequency. The highest-frequency external component might be a 20mhz crystal, which you can lay out just by following the example design in the data sheet.
Most ARMs up to even a few hundred MHz are also pretty easy to lay out.
For wireless you're right, but this is more or less solved by the recent proliferation of cheap plug-in wireless modules that are already certified.
- euyyn 9y agoYou're right that Arduinos are slower. I had things like the Raspberry Pi in mind.
- rjsw 9y agoThe Raspberry Pi will be easier to layout than an equivalent ARM SoC that needs external RAM.
- sokoloff 9y agoUsing a module or not, you still have to go through unintentional radiator testing, though, right (if you have a clock signal on the board over some ludicrously low frequency)?
- kbaker 9y agoYes, if you want to sell your device you will need to go through Part 15 testing. I think the limit is in something like low-digit kHz.
