ESP32-S3 Modular Firmware
Budget: $250 – $750 USD
I’m building an ecosystem of ESP32-S3-based modules and I’d like to bring a seasoned embedded developer on board for the long haul. Every module in the roadmap—starting with the very first one we will tackle together—must combine three pillars: LoRa communication (with robust AES-based encryption), a lightweight web panel served from the device itself, and an on-device GUI rendered on a small display.
For the initial milestone you will deliver fully-tested, production-ready firmware that proves this trio works seamlessly on the S3: flawless encrypted LoRa packets, a responsive web panel for configuration/monitoring, and a smooth GUI (LVGL or comparable) sharing the same data layer. I’m working with ESP-IDF, but I’m open to your preferred toolchain if it speeds us up without sacrificing quality.
Speed matters—I’d like to see the first module running ASAP—yet maintainable architecture is equally important because we’ll be cloning and extending the codebase for many future modules. Please share links or repos that showcase similar embedded or IoT work you’ve done; that’s the single most useful input for me right now.
If you thrive on clean C/C++, ESP-IDF, LoRaWAN stacks, over-the-air updates, and tight GUI/WebSocket integrations, we’ll get along great. Let’s ship the first module quickly and set the foundation for a series of innovative devices.
Proper documentation for each code base should be included as well as git repo creation and implementation.
