Project Info

This is another Aliexpress cheap and very usefull module. I wrote driver for HF-6030 first, which was later ported to other systems.
HF-17576 is datachable (goldpins), so it can be used ad-hoc in various projects.
It is also easy way to create level translator beetween 3.3 V devices and 5 V systems or vice-versa.

Special extension test boards was made for this module: HF-40576.
