This document is a schematic for a PCIeDuino328v1 board. It contains an ATmega328P microcontroller connected to various pins, interfaces and peripherals including digital and analog pins connected to headers, an 8MHz crystal oscillator, USB-to-TTL serial chip, voltage regulators, and other common components. The schematic also includes power and reset connections, and pin labels for the microcontroller and other ICs.
