Ti’s SimpleLink radio line is an ARM Cortex-M4 level of performance (think 100 MHz to 200MHz) for general microcontroller use, with a radio-dsp+CortexM0+ (like ~20MHz) to handle the radio stuff in parallel.
So the chips that make up the Flipper are incredible, and cheaper to experiment with than I expected!
I’m intrigued by one level lower. Flipper is using TI SimpleLink radio-chips. These chips are $5 to $10. https://www.ti.com/lit/ml/swat002b/swat002b.pdf?ts=1690839499774
Ti has created BeagleConnect Freedom as a demo-platform for these SimpleLink chips. That’s just $25.
