|Schematic||I2C ADC Serial Audio Board|
The I2C ADC Serial Audio board is designed to provide 8 channels of 10 bit analog data collection.
It includes two 5 bit digital I/O expansion ports each configured for 10 wire ribbon cables using alternate signal and ground lines.
A 6 pin serial port configured to support FTDI/USB and Bluetooth modules is provided.
The board has a 0.5w @ 8ohm audio driver connected to a high speed PWM port though a 10kHz low pass RC filter and volume control pot.
As with most boards, it also includes an ISP programming header, a +5 voltage regulator, and a status LED.
There is also a jumper to select +5v from either the onboard regulator or the I2C bus.
The board uses a 7-12v DC (9v DC typical) external supply for power.
