I'm aware that nobody actually does this at the hobbyist level, that successful commercial products have been launched without certification, and it's probably something I can't afford if I have to ask. However, I've always wondered about the…

Does anyone know of a microcontroller/DSP with no clock speeds or any oscillators in excess of 1.705 MHz?

I am planning on making a simple electronic device which I might eventually try to market if it works out O.K. Before taking the plunge and trying to mass produce it, I would first try to sell a few on the internet to see if anyone even wants it. It…

Workaround for the obsolete ATTINY15 1.5Mhz clock for FCC exemption?

The ATTINY15's was ideal for designing FCC Part 15 exempt battery powered products since its 1.6Mhz internal RC clock ran just below the 1.705Mhz cut-off. The ATTINY2/4/85 replacement parts come with a 1.6Mhz compatibility mode, but this clock is…

ISM band rules for spread-spectrum: how much do I need to spread?

I'm doing a preliminary study for a 5.8 GHz ISM band data downlink for a cube satellite. I know that spread-spectrum is mandatory for ISM, but the FCC rules seem pretty opaque on how much I need to spread (for DSSS). The only references I could find…
