Explore ESP32-Pico-D4 a new chip by Espressif

Very recently Espressif released a new chip, ESP32-PICO-D4 which includes all required components inside chip. No reason to avoid one!

ESP32-PICO-D4 is a "single chip ESP32 module except for antenna" and it has a great possibility to make lots of thing together with wonderful dual core MCU and WiFi/Bluetooth!! Just put one chip covers Wireless and high-processing power! I cannot avoid to use one and got sample chips and indeed already made several prototype of prototype. I would like to introduces them on this project (and hopefully they will appear on my tindie store soon..)

I will add more information about ESP32-PICO-D4 later but now I briefly explain how it is useful and easy to use.

I quickly made a web radio consists of ESP32-PICO-D4 and PCM5102A DAC. (This PCB has some error so you can see thin wire jumpers... New modified PCB will reach me soon.) Simply swapping ESP32 module and ESP32-PICO-D4 is enough to make it! Ultra easy!

But web radio board has very limited number of GPIO pinout so I quickly made full-GPIO pinout version! Again it is ultra easy to handle!!

Excellent!  Been wanting to play with it myself.  Any chance i can ask you to share your motherboard eagles and LBR for the chip (: Let me know when its on Tindie so I can support your work!
