Espressif Systems’ ESP32-C2 incorporates Wi-Fi 4 and Bluetooth 5 (LE), and was specifically developed to target simple high-volume, low-data-rate IoT applications such as smart plugs and smart lightbulbs.
The chip comes in a 4 mm square package with 272 KB of memory. It runs frameworks such as ESP-Jumpstart and ESP RainMaker, as well as ESP-IDF, which is Espressif’s open-source, real-time operating system for embedded IoT devices. This SoC also continues the tradition of Espressif’s strong security, having features such as secure boot and Flash encryption, while also providing a hardware chain of trust for any applications.
The enhanced RF performance of the ESP32-C2 allows the device to transmit 802.11n packets (72,2 Mbps) with 18 dBm of output power, and it can transmit at the full 20 dBm FCC limit for low data rates..
