How do I wire HC-12 to a microcontroller?
Connect VCC and GND to a 3.2–5.5 V supply and common ground. Cross the serial lines: the module TXD goes to the MCU RX pin, and the module RXD goes to the MCU TX pin. Confirm the logic level matches your board.
Do both ends of the link need HC-12 modules?
Yes. A link needs two modules set to the same channel and compatible settings. The link is transparent, so data sent on one UART is received on the other.
