$13 RPI_AC108 Audio Board Ships with a 4-Mic Array for Raspberry Pi

RPI_AC108 4-mic array for Raspberry Pi

X-Powers is a subsidiary of Allwinner, better known for its PMIC chips for Allwinner Cortex-A processors., but we also discovered X-Powers AC108 quad-channel ADC chip for microphone arrays in 2017. Soon after, Seeed Studio launched ReSpeaker 4-Mic Array for Raspberry Pi, but I had completely forgotten about the audio chip since then. That’s until this morning when I came across RPI_AC108 audio board also coming with four microphones and several LEDs. RPI_AC108 specifications: Audio X-Powers AC108 quad-channel ADC with I2S/TDM output transition 4x MEMS microphones Expansion 2x Grove interfaces (1x I2C, 1x GPIO port using pins 12 & 13) 40-pin Raspberry Pi compatible header working with Raspberry Pi Zero / Zero W / 2B / 3B / 3B + / 4 and other compatible development boards Misc – 12x LEDs (APA102) connected over SPI, GPIO5 enables power Dimensions – 65mm x 65mm x 9mm The board gets its power (3.3V and 5V) from the 40-pin header, and communicate with Broadcom BCM2xxx processor using I2C …

3.5mm/USB Stereo Microphone Could Make Cheap 2-Mic Array

We previously wrote about the possibility of using Sony PS3 Eye camera as an inexpensive 4-mic array as at the time (August 2019) it sold for $7.5, and can still be found for $13 on Amazon. But I’ve come across a potential even lower-cost option with a tiny stereo microphone that connected to the 3.5mm audio jack on your phone or computer and sells for a couple of dollars ($2-$5) on sites like Aliexpress ($2.15) or GearBest. There’s not much in the way of specifications: Uni-directional stereo condenser microphone Left and right channel stereo recording Gold plug for maximum conductivity and minimum noise Sensitivity – 38 ± 3dB Frequency Response – 100-15,000Hz Plug – L-shap gold-plat mini plug, 3.5mm Dimensions – 5.7 x 5.5 cm If you click on the GearBest link, you’ll find there’s both a “mobile phone ” version and a “PC” version. I supposed it was because of different connectors, but I was not sure and found …

Amlogic A113L Dual-Core Cortex-A35 Processor Targets Smart Audio and IoT Applications

Amlogic A113L Meson A1

Over two years ago, we reported about Amlogic A111, A112, A113 processors designed for audio applications such as smart speakers. A111 features four Cortex-A5 32-bit core, while A112 and A113D/A113X processors come with four Cortex-A53 cores instead. We have not heard much about those since then, but all those processors are still listed on Amlogic website, A112 is supposedly used in Xiaomi AI smart speaker, and Amlogic A113X1 Far-Field Dev Kit is still listed on Amazon’s list of devkits for Alexa voice service, but currently out of stock. Amlogic has been working on a more cost-efficient processor for smart audio and IoT applications with Amlogic A113L dual-core Cortex-A35 processor shown as Meson A1 in the Linux source code. It was just added in Linux 5.5. We don’t have much information about it, but it’s interesting as it’s the first Cortex-A35 processor from the company, and it targets the same smart audio application as Rockchip RK3308 quad-core Cortex-A35 SoC found in …
