Product description
The HC-12-USB is a wireless serial communication module that enables simple data transfer between a computer and microcontroller-based systems, such as Arduino. The module combines an HC-12 RF transceiver with a USB to UART interface, allowing it to be connected directly to a computer without the need for an external USB-to-serial adapter.
Communication is handled via serial UART and transmitted wirelessly in the 433 MHz band (transparent transmission). This provides long range and stable communication even in environments with interference. The module is suitable for applications such as remote control, telemetry, wireless data acquisition, and as a serial bridge between systems.
Settings such as channel and transmission speed can be configured via AT commands. The transparent serial transmission means that data is sent without the need for complex protocol handling.
The HC-12-USB is particularly useful for development and testing, where a wireless replacement for wired serial communication is desired.
