R38 Decoder Board Introduction
1. Professional IIS processing chip realizes PCM / DsD output 2.Support 32BIT / 44.1-384 KHZ DSD64-DSD128 output, full frequency music automatic switching 3. Raspberry Pi inputs and plays music through the IIS method. The listening experience is smooth, real and natural, and it is never used. USB way to play the kind of hard-to-detect pause 4. Use universal version VOLUMI0, MOODE Set the IIS-DAC mode to HiFiberry DAC to play. VOLUM0 universal version driver can support 44.1-192KHZ DSD64 MOODE universal version driver can support 44.1-384 KHZ DSD64-DSD128 5. Use imported NDK NZ2520SD crystal to provide high quality low phase noise clock signal for ES9038Q2M 6.LPA op amp adopts OPA1612 op amp with low distortion and low noise. The power supply is dual voltage. Negative 15 volt power supply, effectively exploiting the potential of op amps, not comparable to low voltage or single power supply solutions
Board output specifications: 1.Dual-channel single-ended RCA socket output: 2Vrms / -0dB 2.3.5 headphone socket output: 2Vrms / -0dB (The headphone socket is actually directly connected to the RCA socket, which is not suitable for directly driving the headphones.)
powered by: The 5V power supply of the board is directly connected to the 40P interface of the Raspberry Pi. There are two ways to supply power as follows: a. Directly use micro_ _usb to power the Raspberry Pi, and the Raspberry Pi’s 40P interface provides power to the board b. Power is supplied from the DC socket input interface of the board, and the board supplies power to the Raspberry Pi through the 40P interface ** Only one of the two power supply methods can be used at the same time, and the two cannot be used at the same time Otherwise, the board, Raspberry Pi or power supply will be damaged. The board power interface input specifications are as follows: Power supply voltage: DC stabilized voltage +5V, voltage range: ±5% Power interface specification: 5.5/2. 1, positive inside and negative outside Suggested power supply current: ≥2000MA Single board working current: ≥250MA (excluding Raspberry Pi) The picture on the product introduction is for reference only, the actual product shall prevail, and there may be some raw materials supplied by the market Changes, products are subject to change without notice.
