whats the dip package?

sma connector
some sort of micro with rf out
button cell holder
2 buttons
4 leds
programming/ debug header
dip package doing some level shifting possibly

could be anything

you are quite right, the last one is a solid state relay that commutes the power source between the jtag connector and the cell batery

the package is a qfn48

What Cad software is this?

interesting
still.. an esp8266 board with support components is $5, pretty hard to compete for poor hobbyists like myself

Is it comparable to eagle?

Or something much better like Altirum or Allegro?

>>53891894
the best tool is the one that you know better

Unfortunately, industry begs to differ if you want a job in PCB design. In general all they care about are Altrium and Allegro.
