AudioSOM32
AudioSOM32 is a powerful little audio System-on-Module with integrated LiPo battery management, a dual core processor, WiFi b/g/n and Bluetooth 4.2 radio for battery-powered Internet of Things (IoT) applications.
The integrated stereo audio codec provides direct headphone drive, condenser microphone input with digital bias, stereo line-in and line-out.
Note:
The AudioSOM32 is not available for online purchase at the moment. Please contact us at hello@iot-bits.com for purchasing modules (we have stock!).
Overview
AudioSOM32 measures 20mm x 20mm and is built around the popular Espressif Systems WiFi/BT SIP (System-in-Package), the ESP32-PICO-D4.
The PICO-D4 integrates ESP32 SoC (dual cores @ 240MHz), complete WiFi b/g/n and BT 4.2 EDR radio, 32MBits of flash memory, precision crystal oscillator and other discrete components in a tiny LGA package.
The on-board single cell programmable LiPo charger and a 3V @1A buck regulator make up the power section of the AudioSOM32. The module can be powered directly from USB (5V) to charge a LiPo battery pack or function normally without LiPo cell.
A low power 96kHz stereo NXP audio codec with built-in DSP provides audio recording, playback and mixing capabilities.
AudioSOM32 uses a dedicated low-noise LDO for powering the codec directly from the LiPo cell, which results in exceptionally clean audio playback and recording.
