WAVMAN Overview
WAVMAN is an open source portable PCM audio player based around the ATSAMD21 serieis of microcontrollers and the PCM5102 DAC. It supports SD via an SPI interface.
Revisions and Notes
REV 0
- Wrong symbol for USB-C resulting in only one pair of DP/DM being connected
- DAC does not have 3.3v on VDDIO or VDDIN
- PCM_MUTE (DAC mute) is not connected to MCU or even a pull up resistor to 3.3v so DAC is always muted by default
- The hold switch was botched (not connected to MCU and wrong net for power)
- All displays sink current from the LDO instaed of the battery directly, it may be desirable to change this
- No dedicated debug port for SWCLK and SWDIO
- The audio amp. has is missing several compontents (feedback resistors Rf and decoupling cap.)
- AMP_SHUTDOWN is not connected to the MCU
REV 1
- should fix all major issues with REV 0
- minor tweaks to switch and knob placement
- 0805 passive components
- rerouted audio ICs
- knockout silkscreen for userfacing text
