I guess Espressif had other plans for the competition!&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=24877335&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=24877335&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=24916086&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;news.ycombinator.com&amp;#x2F;item?id=24916086&lt;/a&gt;&lt;p&gt;Skimming over C3 datasheet, it seems it doesn&amp;#x27;t have DAC but has one I2S. BL602 has DAC but no I2S!</text></comment>

The datasheet is also in the comments (&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;mega.nz&amp;#x2F;file&amp;#x2F;nk41mSAL#R_d0njlKRb-aIoGuX6JXUB5eeflAdyruz_11tiuvNF4&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;mega.nz&amp;#x2F;file&amp;#x2F;nk41mSAL#R_d0njlKRb-aIoGuX6JXUB5eeflAdy...&lt;/a&gt; )(chinese pdf) : 160MHz 400k sram apparently single core.</text></comment>
