seeed studio #ad - This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on. Different from respeaker 2-mics pi hat, this board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture.
Besides, raspberry pi would have ability to do vadvoice activity detection, which contains 12 apa102 programmable LEDs. With that 4 microphones and the led ring, this 4-mics version provides a super cool LED ring, estimate DOADirection of Arrival and show the direction via LED ring, just like Amazon Echo or Google Home.
0 This raspberry pi microphone support all raspberry pi models, Pi 3 B, Pi 2 B, Raspberry Pi 1 B+, including Raspberry Pi Zero, Pi 3 B+，Pi 4 B. Respeaker 4-mic array for raspberry pi（pi 3/pi 4 b + is a 4 microphone expansion board for Raspberry Pi designed for AI and voice applications.
seeed studio #ad - Two types audio output socket : 3. 5mm audio jack, JST2. 0 speaker Out. Raspberry pi compatiblesupport raspberry pi zero, raspberry Pi 2 B and Raspberry Pi 3 B, Raspberry Pi 1 B+, Raspberry Pi 3B+ and Raspberry Pi 4.
It is easier to use than micro usb and can supply a larger current reliably. The power requirement of raspberry pi 4 model b is 5v 3. 0a, which is higher than the previous model. Network&bluetoothgigabit ethernet wired lan has also been significantly speeded up from 300mbps of pi 3b + to 1000mbps logical value.
0 is supported. Usb boot is faster and more convenient. Power input connectorthe power input connector of the raspberry pi 4 has been changed to usb type c. Powful cputhe cpu of the raspberry pi 4 model b adopts the latest arm cortex-a72 architecture, which is also used in high-performance smartphones, and has evolved into a real pc. The operating clock has been changed from pi3's 1.
seeed studio #ad - Ultra-low sleep power5 μa, deep sleep model with battery charging chip: BQ25101 chip supported lithium battery charge management. Powerful cpuas the first wireless product in the seeed xiao family, seeed studio xiao nrf52840 has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.
