-I prefer the CZ over the JY for a few reasons – ​it’s ​really small, ​it’s ​really well made, it has the KEY (P34, state pin) already broken out and it does level shifting of all the pins back to the 3.3V required by the HC module, unlike some of the other breakouts.+I prefer the CZ over the JY for a few reasons – ​it is really small, ​it is really well made, it has the KEY (P34, state pin) already broken out and it does level shifting of all the pins back to the 3.3V required by the HC module, unlike some of the other breakouts.
