ESP32-C2

ESP32-C2 has 256 KB of physical RAM, but with default configurations, only 24 KB remains free in typical Wi-Fi + BLE scenarios. This article explores comprehensive memory optimization strategies that can free up over 100 KB of RAM, making complex applications viable on this cost-effective chip.

In this article, we explore a simplified ESP32 boot process using single-image binaries to speed up build and flash times — ideal for development workflows. This approach sacrifices features like OTA updates but enables faster iteration.
