Frequently asked questions
What input voltage does it need?
It accepts 13 V to 62 V DC. As a buck converter, its output must be lower than its input voltage.
How do I connect it to a computer?
Use its TTL serial interface through a USB-to-TTL adapter. Check the module's logic level in its manual before connecting, because a mismatched level can damage the adapter or the module, and share a common ground.
