RDC3-0061W, Digital audio performance display - PCM up to 32bit/768kHz, DSD up to 512. White glow.

The module is designed to indicate the bit rate and sampling rate of digital audio played by Reflex transports from 16 bit/44.1 kHz to 32 bit/768 kHz. In DSD mode, it shows the multiplicity from DSD64 to DSD512. Three address RGB LEDs of the Neopixel type are installed on the board. In ChipStudio projects, they can be assigned an indication, for example, SuperBass, Mute, Input Selector, etc.

Connection diagram and purpose of connectors

The Led output on any Reflex is connected to the "Neopixel In". The output is "Neopixel Out" to continue the line of addressable LEDs.
Boot pins are closed by a jumper when updating the firmware.
DSD Mode pins are closed by a jumper if the display is in DSD display mode.
UART connector for flashing.
Any Reflex is connected to the decoder connector according to the table.

Number	Reflex	Reflex 2.0	Reflex 3.0
0 RES0	23	55	21
1 RES1	22	57	20
2 FS1	25	54	8
3 FS0	26	52	7
4 FS2	27	56	9
5 FS3	-	58	-

Frequency meter mode

For projects with a maximum sampling rate of 192 kHz, the frequency meter mode can be used. In this case, the display will not display a frequency greater than 192 kHz. There will be dashes on the indicators. And it doesn't work in DSD mode either. It is very convenient to use in multi-channel projects such as a home theater.
