For sale is a Raspberry Pi 3 Model B v1.2, with a built-in speaker amplifier, a case, and 5000Ma 24V power supply. It was lightly used as an audio streaming device in my home, and all the features I used are in working order. SD Card and Operating System are NOT INCLUDED. Raspberry Pi 3 Model B specs and features.
Quad Core 1.2GHz Broadcom BCM2837 64bit CPU. BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board. 4 Pole stereo output and composite video port.
CSI camera port for connecting a Raspberry Pi camera. DSI display port for connecting a Raspberry Pi touchscreen display. Micro SD port for loading your operating system and storing data.Upgraded switched Micro USB power source up to 2.5A. Full high quality audio - 192kHz / 32bit. 2 x 55 Watt peak output at 8 ohms (2 x 30 Watt RMS). Includes both a DAC and power amplifier - just connect to your passive speakers. Back-powers the Raspberry Pi over the GPIO (with full HAT compliant protection) at 2.5A so only one power supply required for the whole system.
Plug and play compatibility for ease of use. Hardware and software volume control from your Raspberry Pi. Onboard, hardware jumpers for configuring mute and gain settings (jumpers could optionally be changed with switches).Mute/enable with GPIO22 (this can be overridden by using jumper J4). Compatible with Raspberry Pi A+, B+, 2B, 3B, 3B+, 4B (and also compatible with the Raspberry Pi Zero, but we would recommend the JustBoom Amp Zero for this purpose) any Raspberry Pi with 40 GPIO pins. Optional IR receiver for the JustBoom Raspberry Pi Amp is included in the package. Unused GPIO pins still accessible via a populated extension header. Full driver support in Raspbian. Pre-configured software available on SD cards from various vendors. JustBoom Amp HAT Technical Information. Texas Instruments TAS5756M Amp / DAC chip - 192kHz / 32 bit. A maximum power output of 2 x 55 W (2 x 30 W RMS).
This board powers both the amplifier and Raspberry Pi from a single 2.1mm DC jack power supply. For 8 Ohm speakers, we recommend a 24 volt power supply with at least 75 Watt output power (POWERPAX SW4527 or similar plus C5 cable). For 4 Ohm speakers we recommend a 15 to 19 volt power supply with at least 58 Watt output power (POWERPAX SW4520 or similar). These power supply guidelines will ensure maximum output performance of the amplifier.However there are other options which can be found in our power supply recommendation document. Please note: it is highly recommended to use an external power supply. If you power the Amp HAT over the GPIO pins and do not use one of the recommended power supplies, the maximum output power will be 2 x 3 Watts. Dual inductors on board for footprint efficiency. Fully integrated hardware volume mixing via alsamixer or any ALSA compatible application. Integrated EEPROM for automatic Raspberry Pi devicetree driver configuration. The JustBoom Raspberry Pi Amp is fully HAT compatible.
Optional Vishay TSOP4838 IR receiver included in package (solder yourself if required). Total harmonic distortion (THD+N) of 0.006 % at 1 W, 1 kHz. Signal to noise ratio (SNR) of 104 dB A-Wtd Ref. Ultra low noise voltage regulator for the best audio output (LDO 10uVrms).Fully digital sound path for optimal audio performance. Mute/enable via GPIO22 and also there is jumper J4 for enable, that overrides software enable.
