Description
The Arduino Pro mini Atmega328P LGT8F328P uses the LGT8F328P chip. which its capabilities and functionality are the same as the Arduino pro mini using the Atmega328P chip. For this model, the new LGTF328P chip is made, which is cheaper. And improve efficiency
Has the ability to increase from the original model, such as pin A0-A5. Analog to Digital channel works better than the ADC channel of 8F328P. Readings are finer
0-4095, while Atmega328P read-only 0-1023.
8F328 Board Features
- 8F328P-U MCU used by the LGT8F328P is an Atmel MEGA328P compatible chip.
- 8F328D architecture design is relatively new, peripheral functions far stronger than Atmel MEGA328. Especially the program encryption ability is far more than MEGA328.
- 8F328D can use 3V3 and 5V power supply running at 16M frequency, excellent level compatibility.
- Built-in high-precision RC, no external crystal can be stable operation.
- Less peripheral parts, circuit design is simple.
- 12-bit ADC (analog-to-digital conversion)
- Onboard DAC
- Owned GUID (unique ID) can be used for chip program encryption
- Built-in internal 1.024V / 2.048V / 4.096V ± 1% calibratable reference voltage source

Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model, check
the documentation at http://www.arduino.cc
This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup () {
// initialize digital pin 13 as an output.
pinMode ( 13 , OUTPUT);
}
// the loop function runs over and over again forever
void loop () {
digitalWrite ( 13 , HIGH); // turn the LED on (HIGH is the voltage level)
delay ( 1000 ); // wait for a second
digitalWrite ( 13 , LOW); // turn the LED off by making the voltage LOW
delay ( 1000 ); // wait for a second
