Get up and running in minutes with our simple installation and basic example.
Install the ESP32 GPIO Bridge library via pip.
Upload the modular firmware to your ESP32 board.
Connect and control GPIO pins from Python.
from esp32_gpio_bridge import ESP32GPIO, find_esp32_port
# Auto-detect ESP32 port
port = find_esp32_port()
# Connect using context manager
with ESP32GPIO(port) as esp:
print(f"Firmware version: {esp.get_version()}")
# Digital output - LED control
esp.set_pin_mode(2, "OUT")
esp.digital_write(2, 1) # LED ON
# Analog input - Sensor reading
sensor_value = esp.analog_read(34)
voltage = (sensor_value / 4095.0) * 3.3
print(f"Sensor voltage: {voltage:.2f}V")Professional-grade performance with all critical issues resolved in v0.1.8-beta.

Failsafe System
Transform your ESP32 into a powerful hardware interface with professional-grade Python control.
All critical issues resolved! The ESP32 GPIO Bridge is now production-ready with zero known issues.
Fixed hardware watchdog timer issues that were causing unwanted ESP32 restarts during normal operations.
Enhanced serial communication with robust error filtering and mixed message parsing. No more parsing errors!
Fixed ESP32 hang issues after idle periods by optimizing failsafe mechanism and health monitoring.
Less aggressive failsafe timeouts (30s vs 10s) and simplified health monitoring for better responsiveness.
100% test success rate with zero reboots, zero parsing errors, and stable long-term operation.
Comprehensive testing confirms the ESP32 GPIO Bridge is ready for production use with all core features working perfectly.
