Hi there! On the SCH, the designators are not numbered; all are reset to question marks (?). Also, no part numbers or values are indicated. Are you going to fix it? Are you going to share the BOM?Question by: admin on 2018-12-18 02:23:55
Hi there, please refer to **https://github.com/SeeedDocument/forum_doc/blob/master/reg/ESP32-Audio-Kit_V2.1-Audio.pdf** and **https://github.com/SeeedDocument/forum_doc/raw/master/reg/ESP32-Audio-Kit_V2.1-Power.pdf**. For the BOM, we do not have a plan to release yet. thanks.Answer by: admin on 2018-12-18 02:23:55
I don't see audio specs, and I don't see any audio chips (i2s or otherwise) on the board. Does this imply that all audio goes through the esp32 8bit DACs? That would seriously limit the quality and therefore the usefulness of this board...Question by: admin on 2018-12-18 02:23:54
