FEATURES
PI2AES 2.0 FAQ - Frequently Asked Questions Q: How do I power the PI2AES 2.0 A: The PI2AES 2.0 is designed to be powered from either the 40-pin GPIO 5V or from an external 5V +/-10% supply. Q: Can I power the PI2AES and the PI from the external 5V supply? A: Yes, but using an external supply may still require the Raspberry PI to have it's own supply. See the HW Reference Manual (link below) for more detail. Q: Do the PI2AES 2.0 outputs work simultaneously? A: Yes, all digital audio outputs deliver the same audio data at the same time. This includes the I2S over HDMI. Q: What version of the Raspberry Pi Is the PI2AES 2.0 compatible with? A: The PI2AES 2.0 will work with the PI 3, 3B, 3B+, PI 4 and the PI 5. Q: Are there two different acrylic cases for the PI4 and PI3x? A: We include one acrylic case kit, but two different right side and front plates for the PI3 and PI4. You just assemble which one is appropriate for you. Q: What pinout is supported by the I2S over HDMI? A: PI2AES 2.0 supports both the Gustard Audio and PS Audio pinouts. Q: OK, where do I find a Pi though? A: Check out this awesome website to locate global real time stock for all Raspberry Pi flavors. https://rpilocator.com |

PI2AES 2.0 - PRO AUDIO SHIELD
$249.00
PI2AES 2.0, Professional Studio Grade Audio I/O Shield. Includes Clear Acrylic Case
FEATURES
- FORM FACTOR – Raspberry Pi ® Shield Size w/40-Pin mating connector.
- AES TRANSMITTER – The industry standard WM8804 converts the RPi I2S stream to AES3/SPDIF formatted data at 24-Bit up to 192Khz Frame Rate
- COAX OUTPUT – A 1:1 Isolation Transformer provides Bit Perfect Impedance Controlled Coaxial Transmission of the Digital Audio Data
- SPDIF OPTICAL OUTPUT – Isolated Optical Transmitter Drives Consumer Level DAC and AVR
- BALANCED OUTPUT – An RS-422 Transmitter coupled with a 1:1 Isolation Transformer allows the transmission of balanced audio data via the Professional Audio Standard XLR Connector
- DIFFERENTIAL I2S OUTPUT – A DS2063 Differential Transmitters is used to drive the I2S Bus over a standard HDMI Connector. The Pinout is Selectable Between the PS Audio and Gustard Standards.
- HIGH RESOLUTION CLOCKS – A pair of Ultra-Low Noise NDK NZ2520SDA oscillators allow the WM8804 to operate in non-PLL mode for the lowest possible noise.
- ULTRA-LOW NOISE LDO’s – Ultra-Low Noise LT3045 LDO (0.9uV noise and 80dB PSRR) is used to power the WM8804 AES Transmitter, while a 2nd LT3045 LDO powers the NDK Clocks.
- LOW NOISE PCB LAYOUT – Constructed with 4-layer Split Ground PCB with noise reduction techniques refined from years of High-Speed Mixed-Signal Design work
PI2AES 2.0 includes a PI3 and 4 compatible clear acrylic case.
