Product Info

Description:

As we know TX and RX are LVTTL, meaning 3.3V signals.  But this module can directly connect to   5V TTL signals (take Arduino for example) without any problems, and you don’t need to worry any damages, it will never happen, it is therefore highly recommended to use transistors to interface with a 5V TTL signal. If you need more parameters and features you may find form the wiki page.
