This is a built-in radio that uses the SA818S module from NiceRF Wireless Technology CO.,LTD.
This is a VHF/UHF module with an output of 1W.
 
pattern.
I tried designing something using surface-mount type components for the first time.

You can order PCB manufacturing and component assembly from JLCPCB.

By the way, I haven't placed an order yet.
 
SA818S module.
There are VHF and UHF modules, and a friend of mine is currently inquiring about whether they can obtain JARD's certification.
