REMOVE DAC!!!
clear-sky opened this issue · comments
Hi dear wolle!
in v 3.0 you have used bt module named KCX_BT_EMITTER
i leave in iran ! Iran is sanctioned and does not have access to international stores such as Ali Express!!!
i could not find this module in local stores so decided to use another module
i found f-6988 that uses bk3266 chip -this module can be used as reciever or transmitter
but i found another nice ability in this module! it has I2S input !!! this means DAC can be removed and make radio much more simple!!! (page 30 of first datasheet)

At first glance, it looks complicated. The board has many functions and connections, but not everything is needed. I think it could work.
I used this in another project, it works without programming, the housing can be easily removed
