The dark days herald the arrival of winter and with it Christmas. So it makes sense to start thinking about Christmas presents and the Christmas party.

What could be better than a beautiful Banana Pi from SinoVoip? There are also numerous accessories and accessory products to complement the gift.

Because in the dark and cold days, which you prefer to spend indoors in the warmth, you need a stimulating activity. A multifunctional Banana Pi is perfect for this.

And since the Christmas season is already getting us in a contemplative mood, they are also on special offer, like the BPI-AI-Voice.

Banana Pi BPI-AI-Voice (Microsemi) is a module for speech recognition and can now also be used on Raspberry Pi with Amazon AVS.

Microsemi’s new ZL38063 audio processor is designed for front-end voice applications and features the company’s AcuEdge(TM) technology. This innovative technology consists of highly complex and integrated algorithms that significantly improve automatic speech recognition (ASR) for embedded and cloud-based ASR solutions. The ZL38063 offers audio enhancements with noise reduction and intelligent automatic gain control (AGC), which enables speech recognition even in conditions with ambient noise.

Key Features:

  • Supports two or three microphones for linear or triangular array placement for enhanced audio recording
  • Noise suppression
  • Intelligent automatic gain control (AGC)
  • High-quality echo cancellation for barge-in and full-duplex audio
  • Fully configurable and scalable solution with two microphone configurations for 180° and 360° recordings
  • Improved beamforming technology to improve audio recording in adverse conditions, in the presence of noise and external sound sources
  • Two-way full-duplex voice communication



  • Raspberry Pi 3 / Banana Pi Header P2: I2S port; SPI; 8 GPIO
  • Audio header: JMMA1: digital microphones; analog output; 3 GPIO
  • SPI flash devices: U2: optional SPI flash component for storing the ZL38063 firmware
  • USB J3: Optional USB power and debug port
  • Debug header: JAIB2/2: Auto-tuning header
  • Digital microphone header: JM1-4: optional header for external microphones

UNO with ESP32 for Webduino


  • CPU: Xtensa(R) 32-bit LX6 single/dual-core processor
  • ROM: 448 KB
  • SRAM: 520 KB
  • Flash: 4 MB integrated, max. 4 Flash/SRAM, each Flash max. 6 MB
  • Power supply: 5 V (at) 1 A microUSB or 5.5 mm, 12 V DC port
  • GPIO: 12-bits SAR ADC 18 channels, 2x 8-bit D/A converter, 4x SPI, 2x I2S, 2x I2C, 3x UART, host SD/eMMC/SDIO, slave SDIO/SPI

Another gift idea would be the BPI-UNO32.

BPI-UNO32 is equipped with the ESP-WROOM-32 from Espressif Systems as MCU. ESP32 is a single-chip solution with 2.4 GHz WLAN and Bluetooth connectivity. TSMC’s 40-nanometer technology has excellent values in terms of power consumption, RF performance, stability, versatility and reliability. It is therefore suitable for a wide range of application scenarios.

This Banana Pi has two separately controlled CPU cores, the main frequency can be up to 240 MHz, 448 KB ROM and 520 KB SRAM.

The size is the same as the Arduino UNO R3.

The BPI-UNO32 can be supplied with power via microUSB or a 5.5 mm DC power adapter and has an automatic switching circuit.

LED matrix module


  • Dot size: 5.0 mm
  • Pixel array: 8 x 8
  • Luminous intensity: 40 mcd
  • Packaging dimensions: 60 x 60 mm
  • Reverse voltage (max.): 5 V
  • Forward current (max.): 25 mA

The Matrix LED module would also be a good accessory for a Banana Pi.

This is because the Matrix LED module was specially developed for Banana Pi. The module has 8 x 8 matrix LEDs. Users can customize the images on the display by programming.

Note: A driver board is not included with the module. You need an Infinity Cascade IO extension module to use it.


  • Full color RGB
  • Ultra flat
  • Plug&Play
  • No cables required

Fields of application

  • Scroll display
  • LOGO display
  • Dynamic signage

Of course, the SATA extension cable for Banana Pi R64 and W2 should not be missing.

Data/power combo extension cable


  • 22-pin/7+15-pin male to female M/F SATA Serial ATA power extension cable
  • Length: 29 cm
