OSOYOO ESP32-S3 GPIO Breakout Board w/ LED Indicators, 5V/3A & 3.3V/3A Output Bluetooth Robot and cost-effective implementationKey Features Real Time Visual Debugging Each GPIO pin is equipped with a dedicated LED indicator driven by 74HC04 hex inverter ICs completely isolated from the MCU's GPIO with zero current loading. This non intrusive design ensures ADC accuracy, bus signal integrity (IC SPI UART), and output drive capability remain unaffected. Logic HIGH illuminates the LED; logic LOW turns it off. Instant visual verification without external test equipment. High
