ATmega328P-PU with preloaded bootloader

Operates at 16 MHz (via crystal oscillator)

✅ Power Supply:

Barrel jack input (7–12V DC)

On-board voltage regulator (3.3V and 5V rails)

✅ Programming Interface:

6-pin FTDI header (DTR, RX, TX, VCC, CTS, GND)

Compatible with USB to Serial adapters

✅ User Interface:

One tactile push button for RESET

1 built in LED pin 13

✅ Expandability:

Female headers for all digital and analog pins

Clearly labeled pins: D0–D13, A0–A5, VCC, GND, RESET, 3.3V

✅ Additional Components:

16 MHz crystal oscillator with capacitors

Power filtering capacitors

Pull-up/pull-down resistors
