13 ESP32-C2 (ESP8684 core) is a low-cost, Wi-Fi 4 & Bluetooth 5 (LE) chip. Its unique design
14 makes the chip smaller and yet more powerful than ESP8266. ESP32-C2 is built around a RISC-V
15 32-bit, single-core processor, with 272 KB of SRAM (16 KB dedicated to cache) and 576 KB of ROM.
16 ESP32-C2 has been designed to target simple, high-volume, and low-data-rate IoT applications,
17 such as smart plugs and smart light bulbs. ESP32-C2 offers easy and robust wireless connectivity,
18 which makes it the go-to solution for developing simple, user-friendly and reliable
