Description
- Based on logicgreen 8F328 IC, which is 99% compatible with arduino used ATMEGA238P IC.
- No guarantee fully compatible, the best is to buy a sample and test for your project.
- Pre-loaded bootloder for the IC, you can directly upload sketch to use.
- Support auto upload. Use FTDI FT232RL, CP2102, etc with DTR pin can auto upload like normal pro mini.
- On board power LED, and D13 LED. Reset button.
- Selectable power supply 5V or 3.3V by SMD jumper.
- Same as promini:
- A4, A5, A6, A7 is inside in the board.
- Pull up reserved SMD resistors space for IIC on back side
- Buck order 10% off for more than 50pcs order. Please try sample first, and decide if all good to implement.

Appears to be compatible with Arduino 1.8 IDE and Pro Mini with ATm328P profile. Timing is a bit off; using the millis() function is not at all reliable for precise timing. I recommend using external oscillators or RTM modules for precise time functions.
For €1.25, not bad. Useful for hobby applications, inexpensive permanent installations that aren’t timing sensitive or mission-critical.

Using the LGT8F328P as an Arduino Nano replacement.
Am not able to get the EEPROM.h library to work. What is saved and what is read back from the same eprom memory address does not tie up. The reading error is also random. Sometimes one address will work 100% and then other times is’s a complete failure.
PWM and AI (12bit) seems to work correctly.

Hi, Thanks for bringing up the questions. According to the databook,
1. The LGT328P has 32KB flash, 2KB SRAM, but configurable EEPROM(shared with flash)
2. It does not have independent EEPROM port from the flash, it can be set to simulate as shared EEPROM from flash. This probably need a initialization method, which is not same to standard arduino libarry.
3. There is a method called “LPM” command to read the data structure.
4. We are poor at code, we update a C demo code from EEPROM LGT328P in the git, please see here. https://github.com/Edragon/LGT/tree/master/1-LGT8F328/Demo%20Code/lgt8f328p_eepp Please also take look into the datasheet.
Thank you. Best regards,

Please use latest HSP board files, it has demo sketch to use E2PROM.
