Small and thin (50x20x2mm) Bluetooth beacon with Qi/WPC wireless charging
Nov 10,2025
The goal of the project was to make thin and small BLE beacon that uses Li-Ion battery and can be recharged with wireless charging. Note, it may not work with all Qi/WPC chargers because small receiving charging coil, it is highly recommended to adapt charger by replacing its transmitting coil with small 20mm diameter coil. I've used Wurth 760308101104 coil with Adafruit 2162 Qi/WPC charger module.Final size with LIR2016 module - 50x20x2mm in thin variant. If height is not limited, then battery ...

NEXO-BT - MUSIC RECEIVER
Rossi Aug 24,2025
# NexoBTNexo - in Latin connection - BT - Bluetooth. is a bluetooth receiver born from the need to connect a bluetooth audio receiver to a professional audio system with XLR outputs; something that is not very common on the market and so I decided to create it myself.# How it work?The project is governed by an ESP32 module (ESP32-WROOM-32UE-N8) which, as A2DP Sink, receives music from a device via Bluetooth and sends it via the I2S protocol to an DAC PCM5102APWR which returns two ...

Comparison of Audio Bluetooth 3.0 and 5.0
Jul 05,2025
Coming to bluetooth in audio applications, we have versions from 3.0 to 5.4. In the practical audio application we have to keep 2-3 things in mind. Like we need what is the max power it is consuming, what is the SNR of the received signal and what is the ideal power conditions. Some other parameters like wireless range, noise in signal, DAC resolution and number of bits also play an important role here. Today in the article we will plot them all and see the difference in performance of a 3.0 and...
