they integrate uart, spi i2c the have antenas and so on...modules that you can solder in a pcb, or to pins directly..
The things is...with a SOM you don't even need a arduino, because the SOMs have a stm32 wich is a arm cortex0-4 32 bits, with hardware encryption and so on
But yes it all depends on what you are trying to achive..
RF products, i don'n t buy in china, the diference price, doesn't compensate the bad quality..only if you need to deploy some 30-50 here, you have a point in price diference.
