The LGT8F328P SSOP20 MiniEVB is a compact development board designed as a lowcost, highperformance alternative to the Arduino Pro Mini [citation:1][citation:2]. Powered by the LGT8F328P microcontroller in an SSOP20 package, this board runs at double the speed of a standard Arduino Nano while offering enhanced features such as a higherresolution ADC, a builtin DAC, and a unique ID (GUID) for each chip [citation:1][citation:4]. It is fully programmable via the Arduino IDE.

# Programming Requirements
This board requires an external USBtoTTL serial adapter (e.g., FT232RL, CH340, CP2102) for programming [citation:1][citation:6].
# Arduino IDE Setup
# Known Issue: Auto-Reset
The DTR auto-reset circuit may not function correctly when powered at 5V because the LGT8F328P has a lower reset threshold than ATmega328P [citation:4]. If you experience upload failures, try:
√ Compatible with most Arduino libraries and sketches
√ Direct replacement for Pro Mini in many applications
√ Supports 3.3V and 5V logic systems
√ Built-in internal oscillator for fewer external components
