025 We use Baofeng's "heart" for Our Projects (SA818, DRA818)

Most of us own a Baofeng. It is cheap and does the job. What would you say if we could transplant its “heart” and combine it with a Raspberry Pi or an ESP32? We would get a dirt cheap and compact device for all sorts of analog and digital modes. Links: SA818: https://s.click.aliexpress.com/e/_DCp...
