The ESP32-C3 DevKit offers an affordable, flexible RISC‑V-based platform with BLE 5 support and a rich set of I/O, making it ideal for custom aquarium controllers that need local processing, sensor fusion, or advanced automation logic. Its strong SDK (ESP-IDF), large community, and low unit price speed development and lower prototype costs compared with specialized mesh modules, though it is not focused solely on RF-centric mesh optimization like Nordic or Silicon Labs. Use it when you want a programmable node that can evolve into a smarter local controller while still participating in Bluetooth mesh topologies.

Review Summary
"The ESP32-C3-DevKitM-1 is celebrated for excellent community support, low cost, and easy development workflow, with many users successfully running BLE projects over extended periods; some note limited RAM/flash versus dual-core ESP32 variants and that advanced mesh features may require extra work. Overall it’s seen as a great value and very developer-friendly for BLE mesh prototypes."

The ESP32-WROOM-32D DevKitC is the most powerful and versatile option here, offering dual-core processing plus Wi‑Fi and Bluetooth in one low-cost module, which makes it ideal for aquarium controllers that need cloud connectivity or local ML inferencing. While heavier on power consumption than Nordic nRF52840-based boards, its combination of Wi‑Fi and BLE lets you avoid an extra gateway in installations that require remote monitoring or firmware updates. For feature-rich aquarium equipment that aggregates sensors (including waterproof probes) and streams data to a server, the ESP32 provides the best technical bang-for-the-buck.
