Parral Dev Board

1. The goal of this project is make a powerfull but easy and simple Dev board for begginers, with a friendly desing you can plug it on your breadboard and choose how you want to power up your breadboard. In my design the supply voltaje is configured through a jumper. While you have the option to power it directly from the usb supply voltage (5V), or using the 3v3 voltage regulator output (3V3). In addition you can set the jumper between 5V and 3.3V, and you have option to power up the board from the usb connector or using a 9v battery by the power jack.

Parral deb board has 4 objects to be programmed onboard, 2 leds and 2 push buttoms. Which you can create your own firmware and start with output and input configurations, the "hello word" in embedded systems

I decided to use a DIP-40 microcontroller to give you the opportunity to use only the MCU on your breadboard and use the board like power supply and programer, since it has a programming port and choose between 5V or 3.3V supply voltage.
