ESP32-C3 Adblock

This project shows that effective network-level ad blocking can run on extremely low-cost hardware by shifting blocklists from RAM into flash as compact hashes, reducing memory requirements and eliminating the need for PSRAM. For CIOs and technology leaders, the strategic takeaway is that edge appliances and embedded devices can now deliver practical security and filtering services at materially lower cost, power, and operational complexity—an example of how software architecture choices can unlock cheaper infrastructure without sacrificing capability.
