Buy 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT


Instruction:

If music is the food of love, play on. But make sure you use this super little DAC Module to get the best out of your Raspberry audio!
The DAC Module provides a super affordable high-quality DAC for the Raspberry. Pumping out 24-bits at 192KHz of audio goodness from the Raspberry's I2S interface on the 2x20 pin GPIO header. Since it's digital audio, it sounds really good, much better than the onboard analog audio. The 3.5mm stereo jack comes soldered onto the board already.

Features:

24-bit audio at 192KHz
Line out stereo jack
pHAT format board
Uses the PCM5102A DAC to work with the Raspberry I2S interface

Package includes:

1 x DAC digital to analog converter

Get STM32F103C8T6 ARM STM32 Small System Development Board Module SCM Core Board


Product Description:

This is a core chip based on the STM32F103C8T6ARM core board. Its functions are as follows:
1. The motherboard is based on the most basic MCU circuit, 8M and 32768 crystal oscillator circuit, USB power supply circuit.
2. The core board is divided into two lines, leading to all I / O ports.
3. With SWD simulation debugging download interface, simple and convenient, and fast debugging speed.
4. Use Mirco USB interface, can do USB communication and power supply, USB interface, compatible with ordinary Android mobile phone charger interface.
6. The RTC Crystal Epson brand is easy to start and more stable.
7. With double needles, but the pins are not welded by default. Users can choose the welding direction that suits them according to their application scenarios.

Chip description:

Packing type: LQFP
Number of pins: 48
Core: Cortex-M3
Working frequency: 72MHz
