​PI2AES-LITE - Pro Audio Shield


FEATURES

FORM FACTOR – Raspberry Pi ® Shield Size w/40-Pin mating connector. 
AES TRANSMITTER – The industry standard WM8804 converts the PI I2S stream to AES3/SPDIF formatted data at 24-Bit up to 192Khz.
AES COAX OUTPUT – A 1:1 Isolation Transformer provides 75-ohm Impedance Controlled Transmission of the Digital Audio Data via AES Standard BNC.
SPDIF OUTPUT – A 1:1 Isolation Transformer provides Bit Perfect Transmission of the Digital Audio Data via RCA Jack.
TOSLINK OPTICAL OUTPUT – Isolated Optical Transmitter Supports Consumer Level DAC’s and AVR’s.
HIGH RESOLUTION CLOCKS – A pair of Ultra-Low Noise NDK NZ2520SD oscillators allow the WM8804 to operate in non-PLL mode for the lowest possible noise. 
ULTRA-LOW NOISE LDO’s – Dual, Ultra-Low Noise LT34042 LDO’s (0.9uV noise and 80dB PSRR) are used to supply the WM8804 AES Transmitter and the High-Resolution NDK Clocks for extremely low Jitter.

PI2AES-LITE FAQ - Frequently Asked Questions

​Q: Do the PI2AES-LITE outputs work simultaneously?
A: Yes, all digital audio outputs deliver the same audio data at the same time. 

Q: Which  versions of the Raspberry PI is the PI2AES-LITE compatible with?
A: The PI2AES has been tested on the PI 3, 3+ and 4

Q: What power supply do I need for the PI2AES-LITE?
A: The PI2AES-LITE is designed to operate from the Pi 5V Power Supply via the GPIO 5V pins. 

Q: Can I power the PI2AES-LITE from an external linear PSU?
A: The PI2AES-LITE DC Jack allows an external 5V source. However, due to an excessive voltage drop, this source can not also power the PI. The PI_PWR jumper (see the  manual) must be removed and the PI powered from it's own PSU. 

Q: Does the PI2AES-LITE  come with a case?
A: Yes, an acrylic case is provided with two different right side and front plates for the PI3 and PI4. You just assemble which one is appropriate for you.

Q: Is the PI2AES-LITE compatible with the software for the PI2AES?
A: The PI2AES-LITE uses the same core design as the PI2AES and will support all of the same software. The same drivers can be used for both.

You need to change the I2S DAC setting to "HiFiBerry Digi+ Pro" Note that this does not refer to the external DAC, but instead is used to load the proper driver for the PI2AES-LITE. See screenshot below for the proper setting.
