Gaggimate is an ESP32-based smart control upgrade for Gaggia espresso machines, providing a custom UI for temperature monitoring and pump control. It leverages the FreeRTOS-based ESP32 platform using LVGL and TFT_eSPI for its display interface, and NimBLE-Arduino for wireless connectivity.

This project transforms an ESP32 into a bridge between wired USB peripherals and Bluetooth-enabled hosts. By combining software-defined USB host capabilities with the NimBLE stack, it allows standard USB keyboards and mice to function as wireless BLE devices across multiple operating systems.

NimBLE OTA is a specialized library for ESP32 devices that enables firmware updates over Bluetooth Low Energy (BLE). It leverages the memory-efficient NimBLE stack to provide a robust OTA service, featuring secure authentication, progress tracking, and compatibility with both Python-based and web-based upload tools.

An ESP32-based firmware that extracts vehicle data via an ELM327 OBD2 adapter and transmits it to an MQTT broker over cellular networks. Designed for Home Assistant integration, it supports a wide range of LilyGO T-Call and Waveshare modules with integrated GSM/LTE and GPS capabilities.

A versatile ESP32-based firmware designed for offensive security and Red Team operations. It supports a wide range of hardware including M5Stack and Lilygo devices, providing features for WiFi attacks, BLE manipulation, RF/RFID interaction, and a built-in JavaScript interpreter.

A high-performance ESP32 firmware for DCS World cockpit panels using the DCS-BIOS protocol. It supports native USB HID, WiFi, and Serial transports while providing drivers for various displays, LEDs, and input devices with a focus on static memory allocation and non-blocking I/O.

An intelligent arousal management system for ESP32 that connects to Lovense devices via Bluetooth LE. It uses a pressure sensor for automated edging control and features a real-time web dashboard for monitoring and configuration.

Firmware for an ESP32-C6 based E-Paper display device featuring BLE provisioning, AWS IoT connectivity, and OTA updates. It targets the Spectra 6 7.3-inch display and integrates motion sensing via the KXTJ3-1057 accelerometer.

A firmware project for ESP32-S3 that acts as a USB-to-BLE HID bridge, allowing Bluetooth controllers like the Xbox Wireless Controller to be used with the Nintendo Switch. It utilizes ESP-IDF, FreeRTOS, and the TinyUSB stack to emulate a Nintendo Switch Pro Controller over USB while acting as a BLE GATT client.

A multi-platform LoRa Terminal Node Controller (TNC) firmware supporting ESP32, nRF52, RP2040, and STM32. It provides a serial CLI for raw LoRa interaction, BLE packet sniffing, and a KISS-TNC mode for APRS, AX.25, and IP-over-LoRa networking.

An ESP32-C3 based smart thermos that measures liquid temperature using an NTC thermistor and displays it on a 1.28-inch round capacitive touch screen. The project utilizes the LVGL library for its user interface and NimBLE for Bluetooth connectivity.

A comprehensive open-source firmware for the LilyGo TWatch 2020 series based on the ESP32 and Arduino framework. It features a custom UI engine, Lua scripting, BLE/WiFi connectivity, and integration with Gadgetbridge for smartphone notifications.

An ESP32-based open-source universal remote firmware utilizing the Arduino framework and LVGL for its graphical user interface. It supports device control via Infrared, Bluetooth Low Energy keyboard emulation, and MQTT for smart home integration, featuring a cross-platform simulator for desktop-based UI development.

A portable suite of WiFi and Bluetooth offensive and defensive tools built for the ESP32 microcontroller. It enables security researchers to perform packet sniffing, beacon spamming, and network analysis through a dedicated handheld interface utilizing the Arduino framework.
