With the current line of accessories? like the https://www.tindie.com/products/electromage/electromage-pixelblaze-sensor-expansion-board/ ?
Yes, these expansions are compatible with the esp32 version of Pixelblaze. It will be announced very soon too!
That is some VERY exciting news. I can’t wait! My next order will be both the new PB and PB-sensorboard. I like to minimize my shipping cost.
