- | I prefer the CZ over the JY for a few reasons â itâs really small, itâs 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 â 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. |
Of course, some of the US manufacturers make some great boards with superior features and wonderful quality control, but that comes at a price - personally I like paying $4 for a bluetooth module, rather than $25-30. | Of course, some of the US manufacturers make some great boards with superior features and wonderful quality control, but that comes at a price - personally I like paying $4 for a bluetooth module, rather than $25-30. |
