AK4118 Digital Receiver Board Optical/Coaxial/I2S Input to I2S Output Audio Accessory for DIY Users

Features:
- Its chip has been upgraded from AK4113 to AK4118
- Support two-way coaxial inputs, one-way optical input and one-way I2S signal input
- Support 32K~192K sampling rate (sampling rate up to 768K for I2S input)
- DSD transmission can be supported when there is I2S input. The I2S input level supports 3.3V or 5V
- Support I2S/RJ-16/RJ-24/LJ-24 output format. The default output format is I2S (pass-through mode at I2S input, regardless of format)
- Optional LCD1602 or 0.96" OLED screen can display the input source. When there is coaxial or optical input, it will display the corresponding digital format/sampling frequency/number of bits. When there is I2S input, it can display the sampling frequency/number of bits. When there is DSD input, it can display DSD-64/DSD-128/DSD-256/DSD-512.
- Change the input source by touch switches. With memory function. There are two modes:
1. OP1 open-circuit ----> select coaxial input 1/coaxial input 2/optical/I2S inputs respectively
2. OP1 short-circuited (default) ----> coaxial input 1/coaxial input 2/optical input automatic selection and I2S input
- Choose LED light or screen display: 1. OP2 open-circuit (default) ----> display. 2. OP2 short-circuited ----> LED light. The LED light of input channel will be lit
- Power supply: DC 5~12V

Package Included:
- 1 x Digital receiver board
- 1 x I2S output FFC cable

Note:
- LCD1602 and 0.96" OLED screens are optional. You can purchase the versions with a screen in our store. Thank you!
