rBoot: Open-Source Bootloader for ESP8266
An open-source bootloader for ESP8266 modules and development boards, allowing firmware updates over WiFi or serial connection without full chip erase.
What is RBoot?
rBoot is an open-source bootloader specifically designed for ESP8266 WiFi modules and development boards. It enables over-the-air (OTA) firmware updates via WiFi or wired serial connection without requiring a full chip erase.
Key features of rBoot include:
- OTA firmware updates over WiFi or serial - update firmware wirelessly without needing physical access to the device
- Dual boot slots for failsafe firmware updates - if an update fails, automatically roll back to the previous working firmware
- Partial chip updates - only update modified parts of firmware to save time and bandwidth
- Open source and customizable - source code is fully available to edit and adapt as needed
- Small memory footprint - space efficient to leave more room for user applications
- Compatibility with popular ESP8266 development boards like NodeMCU, Wemos, etc.
rBoot is commonly used in IoT devices, sensors, automation systems and other embedded applications where remote updates are necessary. Its dual boot feature provides safety during OTA updates. The project is hosted on GitHub and works with the Arduino IDE as well as Espressif's IoT Development Framework.
