=== 8F328 Board Features ===
 
* 8F328P-U MCU used by the LGT8F328P, is a 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)
 
* On board 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

=== Use in arduino IDE LGT8F328D ===
 
* All of our boards already had arduino bootloader
 
* Install larduino HSP from here [[DL]] to get support in arduino IDE, install guide refer to "Install.txt"
 
* Choose board '''larduino-core w/LGT8F328D''', the rest is the same as use arduino pro mini.
 
* Detail guide please see here. [[File: LGT8FX8D_mini_arduino_app.pdf]]
