NeoEsp32I2s1800KbpsMethod supports any available pin below 34.
This method uses i2s hardware support to send data to the NeoPixels. Thus this method uses very little CPU for actually sending the data to NeoPixels but it requires an extra buffer for the I2s DMA to read from. Thus there is a trade off of CPU use versus memory use. The extra buffer needed is four times the size of the primary pixel buffer.
**NOTE:** The eps32 supports two i2s hardware buses. The first one is left open for other uses. If for some reason you need to use the first one, then use NeoEsp32I2s0800KbpsMethod instead.

## NeoEsp32I2s1400KbpsMethod
Same as NeoEsp32I2s1800KbpsMethod but running at the older and slower data rate.
