ESP32-C2 Features

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

Features include the following:

32-bit core RISC-V microcontroller with a maximum clock speed of 120 MHz
2 MB or 4 MB in chip (ESP8684) or in package (ESP32-C2) flash
272 KB of internal RAM
802.11b/g/n
