Mercury V2 Update - 02/10/2023
75 Mercury V2 Streamers are  now available with ~1 week deliver (we have to do a little assembly work and testing before shipment). After this we don't know when we'll have them again. Our order for 200 CM4 compute modules placed last September has a current ETA of Dec. 21 this year. That was already pushed out from the original of August.

Announcing the PI2AES-LITE, Digital Audio HAT

Production Status -  In stock, ships in 1-2 business days.
The PI2AES-LITE, designed and manufactured by PI 2 Design, is a professional I/O Shield designed to bring Professional Studio Grade Audio to the Raspberry PI ® 3, 3+ and 4 series of Single Board Computers.  This HAT compatible board converts the Raspberry Pi ® I2S Interface to High Definition AES Coax, SPDIF and Toslink Digital Audio Outputs. Fully Compatible with all PI2AES software.

​The major features of the PI2AES-LITE are as follows:
  • FORM FACTOR – Raspberry Pi ® HAT 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 Frame Rate. The PI2AES-LITE works with the industry standard WM8804 w/multiple clocks, Linux driver.
  • MULTIPLE SIMULTANEOUS OUTPUTS – All output ports are active with the same Digital Audio Data , Bit Depth and Frame Rate at the same time. No further configuration required.
  • AES COAX OUTPUT – A 1:1 Isolation Transformer provides Bit Perfect Impedance Controlled Coaxial Transmission of the Digital Audio Data.
  • SPDIF OUTPUT – A 1:1 Isolation Transformer provides Bit Perfect Transmission of the Digital Audio Data via RCA Jack.
  • SPDIF OPTICAL OUTPUT – Isolated Optical Transmitter Drives Consumer Level DAC and AVR.
  • 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 LT3042 LDO’s (0.9uV noise and 80dB PSRR) is used to Supply the WM8804 Transmit Section and the High-Resolution 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.
  • EXTERNAL 5V POWER - The PI2AES-LITE is designed to operate on 5V from the Raspberry Pi. Optionally, external 5V can be supplied for use with low noise Linear PSU’s

FEATURES

AES TRANSMITTER – The industry standard WM8804 converts the RPi I2S stream to AES3/SPDIF formatted data at 24-Bit up to 192Khz Frame Rate

SPDIF COAX OUTPUT – An RCA connector with Isolation Transformer provides coaxial transmission of the SPDIF Audio Data Stream.

SPDIF OPTICAL OUTPUT – Isolated Optical Transmitter Supports Consumer Level DAC and AVR inputs

AES BNC OUTPUT - A 75 ohm BNC connector with Isolation Transformer provides for Single Ended AES transmission.

AES BALANCED OUTPUT – An RS-422 Transmitter coupled with Isolation Transformer allows the transmission of balanced audio data with 110 ohm impedance via the Professional Audio Standard XLR Connector

BUFFERED I2S OUTPUT – Parallel Buffered I2S is available for direct short distance connection to off-board D/A. Perfect for DIY use! I2C for control is also provided as well as 5V Regulated and Input Voltage Rails

DIFFERENTIAL I2S OUTPUT – A DS2063 Differential Transmitter is used to drive the I2S Bus via LVDS over a standard HDMI Connector. The Pinout is compatible with Gustard I2S Interface. PS Audio is possible, but the left/right channels will be swapped.

***Estimated ship date is April 1st***

***PSU Input Voltage is +19V to +36V***

***Raspberry Pi not included. Cases and 24V PSU sold separately ***
