# Pico+
[Video Demo](https://www.youtube.com/shorts/jsLF4tYyZew)

This is my take on the Raspberry Pi Pico 2. It features:
- RP2350A
- USB C
- A very stable 3.3V power supply (TPS7A20)
- A WS2812 LED
- A reset button (!!!)
- Large SPI flash on SPI0
- Large PSRAM chip on SPI1

I wanted to make this project as the stock pico is kinda underpowered, and I wanted to make a overkill version. While making this project, I did have to reduce my scope by removing the I2C EEPROM and some other features. However, I'm really happy with the resulting board.

Note: this is more or less a direct export of my LCSC cart. Most parts have a minimum order quantity, hence the large quantities.
