Hey -
I pulled the WT2003 off of the qwiic board to make my own PCB stand-alone MP3 player. Following the schematics of the qwiic module and the datasheets I connected everything up and I’m connecting the UART directly to my PC for testing.
Does the Sparkfun onboard WT2003 have some custom firmware installed that might be preventing it from working on its own?
I don’t know if this is the best place to get help with this but more tech details - The only thing I’m able to get without a fail response from the chip is querying the connection status which indicates a PC connection but no Udisk or SDcard present (0x08). I’ve tried the SD card wired in both normally and in SPI.
If anyone has more detailed experience with this chip I’d love the help.
