Qualcomm has recently unveiled an earbud reference design based on the company’s QCC5141 low-power premium-tier Bluetooth SoC that supports TrueWireless Mirroring and Hybrid Active Noise Cancellation (ANC). What are TrueWireless Mirroring and Hybrid ANC? Qualcomm TrueWireless Mirroring technology relies on only one earbud to maintain the Bluetooth connection with the smartphone, while the secondary bud mirrors the connected bud. If the connected earbud is removed, the secondary earbud assumes the connection with zero interruption. The technology enables both a better, more stable connection and lower power consumption Hybrid Active Noise Cancellation (ANC) is designed to provide high-quality immersive experiences and enable natural leak-through of noise to allow for awareness of surroundings. Qualcomm ANC is fully integrated into this QCC5141 chip to reduce the complexity, cost, and PCB space of adding ANC to earbuds and hearables. QCC5141 Earburd Reference Design Key features and specifications: WiSoC – Qualcomm QCC5141 single-chip Bluetooth SoC with power management, dual audio DSP @ 120 MHz, application […]
Last April, we wrote about Edgeless EAI-Series dual Arm Cortex-M4 MCU equipped with a 300 GOPS CNN-NPU for AI at the very edge as we had discovered the chip in an upcoming Banana Pi board. It turns out Banana Pi BPI-EAI80 development board powered by Edgeless EAI80 AI microcontroller has just launched for $16 on Aliexpress, or you could get a complete kit with a touchscreen display, a camera, and a USB power supply for $80. Banana Pi BPI-EAI80 development board specifications: System-in-Package – Edgeless EIA80 dual-core Cortex-M4F microcontroller @ 200MHz with 300GOPS AI accelerator (CNN-NPU), 384KB of SRAM including 256KB for CNN-NPU, and 8MB SDRAM Storage – SPI flash Display I/F – LCD connector up to 1024×768 Camera I/F – 1x DVP camera interface Audio – 2x onboard microphones Connectivity – 2.4GHz 802.11b/g/n WiFI 4 using ESP8266 module USB – 1x USB 2.0 Type-C port Expansion 40-pin GPIO header (multiplexed with LCD interface) CANBUS 2.0 A/B header Debugging / […]
Rakoit launched Up2stream WiFi audio board in 2018, followed by Up2stream Pro board in 2019 with additional Bluetooth, Ethernet, and USB interfaces. Those boards are designed to bring network connectivity to speakers for audio streaming. The company has now launched updates with the launch of Up2stream Mini v3 and Up2stream Pro v3 connected audio boards. Both Up2Stream Mini v3 and Pro v3 have gotten similar updates with the ability to use the board as a micro USB sound card so you can directly plug it into a PC to make it work as a USB DAC. The boards also added SPDIF out, an ADC KEY input for external buttons, two I/O for extensions such as volume knobs. Up2stream Mini v3 now includes both WiFi and Bluetooth 5.0 connectivity. Shared key features and specifications of the boards are as follows: Audio Output – 3.5mm audio jack and header (shared), I2S & S/PDIF (44.1 kHz) headers Input (Pro v3 only)– 3.5mm audio […]

M5Stack has just launched Atom Echo, a coin-sized programmable Bluetooth speaker based on Espressif Systems ESP32-PICO-D4 system-on-package. The company sent me an early sample to play with before launch… but let’s have a look at the specification before checking the device further. Specifications: SiP – Espressif Systems ESP32-PICO-D4 system-in-package with ESP32 dual-core processor @ 240MHz Wi-Fi, BLE 4.0 and 4MB flash Audio 0.5W/NS4168 I2S speaker SPM1423 PDM microphone Expansion 5-pin + 4-pin headers with 6x GPIOs, UART, 5V, 3.3V, GND 4-pin digital Grove header with 2 I/Os, 5V and GND Misc – RGB LED (SK6812), Function (Top – G39 pin) and reset buttons (side), IR LED Power Supply – 5V/500mA via USB-C port Dimensions – 24 x 24 x 17mm (plastic material) Weight – 10 grams The Bluetooth speaker is really small, but you may think CNXSoft has big hands and fat fingers so it makes the speaker smaller than it really is, so I also a photo of the […]
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.
