This Module is a Rotary Incremental Encoder. It encodes the shaft rotation signal and outputs the signal by electronic pulse. The Grove –Encoder is a module of the Grove series and has a standard Grove interface. When you need to add a knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this should be your first choice.

The HC-12 433MHz Transceiver is a wireless communication Module, which is based on the RF SI4463 chip, has a built-in microcontroller and can be configured by AT commands, the maximum output power is 100mW (20dBm) and the receiver sensitivity differs from: 117dBm to -100dBm, depending on the transmission speed. Accepts 3.2V - 5.5V and can be used with 3.3V and 5V UART voltage devices.
