Note: This post documents our hardware design journey. Final implementation: ESP32-S3-based board with ports for 4 sensors (pH, temperature, NPK, moisture) as per government voucher deliverables.

Prototyping can only take us so far. It’s time for Dragonfly Lake to move our hardware into the next stage of maturity.

While many teams jump straight to fully custom boards, we’re taking a different approach for our first PCB.

We want our PCB to be compatible with existing development boards, for a very practical reason.
