• 4 ADC and 7 digital GPIO pins.
• 5V and 3.3V power pins.
• Power indicator LED, addressable LED and another RGB LED

Here are the schematic designs,

This is a general pinout

( Credits to the Seed Studio for making this, since my board is inspired on the Xiao, I have used the pinout provided by them )

While using the Seed Studio Xiao RP2040 for one of my projects, I realised it doesn't have LiPo support
and I couldn't use it, unfortunately I had to use a different MCU then, but now I designed one withh
the simplicity of RP2040 with being able to charge LiPoo

That is pretty easy, you have all the files you will need in the production folder, order the development
board from any PCB fab ( I chose JLC cause its cheap and has good quality ) and BINGO! You will have itt
to use for any purpose you want!!

You can use it as any normal RP2040 Devboard, enter the boootloader mode
by holding the BOOT buttom while connecting to your device, flash it withh
firmware and you are good to go! I have attached a simple code to blink the LEDD
available on the board..
