<p style="text-align: justify;">The PI4IOE5V6408 I²C I/O expander provides additional GPIO pins beyond the ESP32-C6's native capabilities, used for controlling the LoRa® subsystem (antenna switch, LNA enable, reset) and providing expansion port pins. It operates on the shared I²C bus (address configurable) and offers interrupt capability for event detection.</p>

<p style="text-align: justify;">Two PI4IOE5V6408 I²C I/O expanders provide additional GPIO pins for the system. These devices operate on the shared I²C bus with configurable addresses, allowing control of a wider range of peripherals while keeping the ESP32-C6's native GPIO resources for other functions.</p>

<p style="text-align: justify;">The first expander manages display control signals, status indicators, and power monitoring functions. The second expander handles user interface elements such as programmable buttons, manages LoRa® transceiver control signals, and provides GPIO for external expansion connectors. The I/O expanders also offer interrupt capability for event detection.</p>

<p style="text-align: justify;">The Grove connector provides both power (5V from boost converter) and signal connections. IO_0 and IO_1 are controlled through the GPIO 5 and 4, accessible via I²C commands. Use this connector for Grove modules requiring 5V operation or GPIO control.</p>
