LQFP32 / Pro Mini compatible

The LGT8F328P LQFP32 5.0V MiniEVB Development Board (BTE17-14) is a compact, high-performance microcontroller platform designed as a direct replacement for the classic Arduino Pro Mini. It retains the familiar Pro Mini form factor and pin layout while delivering significant performance and peripheral upgrades through the LogicGreen LGT8F328P microcontroller.

At the heart of the board is the LGT8F328P, an enhanced 8-bit RISC microcontroller that runs at up to 32 MHz — double the clock speed of the standard ATmega328P . It maintains 99% compatibility with the ATmega328P architecture, meaning existing Arduino code and libraries generally work without modification . The chip integrates 32 KB Flash, 2 KB SRAM, and configurable EEPROM (emulated from Flash) .

The LGT8F328P brings several features not available on the standard ATmega328P. It includes a 12-bit ADC with up to 8 analog channels (compared to the 10-bit ADC on the ATmega328P), providing finer resolution for analog sensor readings . A 1-channel 8-bit DAC enables true analog output without external components . The chip also features a computing accelerator (DSC) for faster integer operations, and high-current push-pull I/O pins capable of driving LEDs and small loads directly .

This 5.0V version provides logic-level compatibility with standard Arduino shields and 5V sensors, making it a drop-in replacement for Pro Mini projects . Programming is done via UART using an external USB-to-TTL serial adapter, or through the ISP/SWD interface for advanced debugging .

Development is fully supported through the Arduino IDE with the lgt8fx board package, available via the Boards Manager . Once installed, you can select the appropriate LGT8F328P board type and program the module just like any Arduino board.

Whether you are upgrading from an ATmega328P project, building a compact sensor node, or exploring a low-cost 32 MHz microcontroller with enhanced analog capabilities, the LGT8F328P 5.0V MiniEVB offers a compelling balance of performance, compatibility, and value.
