Qualcomm QCC5141 Earbud reference design supports TrueWireless Mirroring and Hybrid ANC

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 […]

Giveaway Week – M5Stack Atom Echo ESP32 Speaker

I reviewed M5Stack Atom Echo Bluetooth speaker powered by ESP32 earlier this year, and that will be the fifth prize of Giveaway Week 2020. It’s very much like a (low-quality) Bluetooth speaker, but you can program it with the Arduino IDE to do whatever you want. There’s also a Grove connector and I/O headers to control external modules. There’s no battery, so a USB-C cable is needed for power. To enter the draw simply leave a comment with your country and whatever else you’d like to say. If the country is missing, I’ll consider the entry void. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or email address. Contests are open for 48 hours starting at 11 am (Bangkok time) every day. Comments will be closed after 48 hours. If comments are open, the contest is still going on. Winners will be selected with random.org, and announced in the […]

Beelink GS-King X Review with Android 9 – Video & Audio Playback, NAS/File Server Function, and Benchmarks

Last month I received Beelink GS-King X for review and started with an unboxing and teardown to check out the hardware. I’ve now had time to test the device with Android 9 including the file server function, a key selling point since of the device since it supports up to two 3.5″ SATA drives internally. A Tedious and Frustrating Start Eventually, I managed to boot the TV box and access the launcher, but it was no pleasure cruise. The first time, I connected the power, there was nothing at all, with the LED turned off, and no noise from the device. I thought the device was dead. The company asked me to check the power supply, and indeed a quick check with a multimeter confirmed it was dead despite the blue LED (on the power supply) implying the contrary. Nevermind, bad things happen, and the company sent me a new power supply, and the TV box could start… But… Oh […]
