Expansion Shield x400 for Raspberry Pi B+/2B/3B

The X400 Expansion Shield is an incredibly cost - effective audio hat designed to fit seamlessly on the GPIO of Raspberry Pi Model B+, Raspberry Pi 2 Model B, and Raspberry Pi 3 Model B. It offers a top - notch audio experience with its i2S interface audio solution, supporting 24 - bit/192KHz high - quality sound. You can easily connect it to other audio equipment via the RCA lotus socket. There's a built - in high - fidelity headphone amplifier, so you can directly plug in a 3.5mm audio jack. The shield comes with two digital amplifier output ports, allowing you to directly connect up to 2 x 30w speakers. Transform your Raspberry Pi into a lossless audio player or a network radio with this amazing hat. We suggest using OS images like Volumio, RuneAudio, PiMusicBox etc. Note: The Raspberry Pi is not included in the box. Specification details: It has an input voltage that can convert 6V to 24V DC to 5V, 3A via a step - down DC/DC converter to power the Raspberry Pi. The audio features full - HD quality, up to 24 - bit/192kHz playback, class - leading audio with 112db SNR and THD of 0.0019%, and an audiophile TI Burr Brown 32 - bit/384kHz DAC. It uses digital I2S audio signals to reduce CPU load. There's integrated hardware volume control, and you can enable or disable mute, earphone AMP, and the main AMP via jumpers. It has Phono/RCA connectors, a 3.5mm stereo audio jack, and speaker terminals. There's also a built - in IR sensor for wireless control. Other features include a power output socket, a DIP switch to remove connection from RPi's pin header, and it can be directly connected on top of the Raspberry Pi without wiring or soldering. The pin mappings are identical to the 40 - pin header of the R - Pi to support existing expansion boards. It has dimensions of 85 x 56mm, the same footprint as the Raspberry Pi. You'll get driver download and a user manual. The shipping list includes one X400 Expansion Board, four Nylon Spacers (M3 x 20mm), eight Nylon Screws (M3 x 6mm), and two Jumper Wires.

Using the X400 Expansion Shield is a breeze. First, place the shield directly on top of your Raspberry Pi Model B+, 2 Model B, or 3 Model B using the board GPIO header pins. No wiring or soldering is needed. Connect your speakers to the digital amplifier output ports, or plug in your headphones to the 3.5mm audio jack. You can also connect other audio equipment via the RCA lotus socket. To power your Raspberry Pi, make sure to provide an input voltage between 6V and 24V DC, which will be converted to 5V, 3A via the step - down DC/DC converter. You can control the volume using the integrated hardware volume control, and enable or disable features like mute, earphone amplifier, and main amplifier via the jumpers. When using the shield, keep in mind that the Raspberry Pi is not included in the box. Also, make sure to handle the shield carefully to avoid any damage. For maintenance, just keep it clean and dry. If you need to update the software, you can download the driver and refer to the user manual for guidance.
