The status of pin 25--a very important pin for sound--on the moddable two is confusing, and would appreciate clarification.
The product info page for the Two clearly shows pin 25 routed out to a pad labelled both GP25 and SPK +. Weirdly, however, while the photo looks like my Two in most respects, the product photo's PCB silkscreen actually says moddable one.
On the Moddable Two that I received, pin 25 is just not broken out at all, full stop.
Did I get a wrong revision of the board, or the right one? If the later, why was the pin 25 breakout removed? I can understand why you might have decided to not break it out as an I2S internal DAC speaker driver circuit, but not breaking it out at all just makes it very hard to use I2S (which the ESP's excel at). While technically the matrix allows I2S from other pins, I haven't been about to get it to work and several knowledgable ESP32 sources have said it's unlikely to work in most scenarios due to timing issues.
Everything about the Two, an integrated ESP32 + cap touch screen, screams to be paired with I2S sound and an SD card. Even though the Moddable SDK doesn't allow it for the Two, I have been able to get an sdcard working via HSPI by using the Arduino IDE instead (why no HSPI support for the Two in the Moddable SDK?), but the lack of pin 25 access has left me crestfallen.
Is there any reason to not solder a wire onto the pin 25 pad directly (other than soldering skill ability)?
