ESP32-PICO-D4 Double Decker MK2
The initial "double decker" had some disadvantage of "non full pinout from ESP32". In most prototyping, the pinout with the previous version is enough but in some specific application, for example Amazon Alexa experiments, requires more pins than the original one. Now the revised "double decker" is born with full-pinout!! https://www.tindie.com/products/micro...
Have fun!
