Espressif launched the ESP8266 in 2014 and the ESP32 two years later. The ESP8266, with its Wi-Fi-only-MCU, facilitated simple connectivity use-cases, while the ESP32 addressed use-cases that required dual connectivity (Wi-Fi + Bluetooth/Bluetooth LE), considerably more computing power, and/or strong security features.
These two chips became the undisputed segment leaders in the hobby electronics and IoT sectors. These devices power a huge number of connected devices.
Meet the ESP32-C3 – A RISC-V Micro
ESP32-C3 is a single-core, 32-bit, MCU based on the RISC-V ISA (Instruction Set Architecture). It has 400KB of SRAM, and runs at 160MHz. The ESP32-C3 has built-in 2.4 GHz Wi-Fi and Bluetooth LE 5.0 with long-range support. It offers 22 programmable GPIOs that have support for all the most popular peripherals such as ADC, SPI, UART, I2C, I2S, RMT, TWAI, and PWM.
ESP32-C3 Can Function As A Host or a Client
ESP32-C3 also supports hosted mode. This means you can use this chip to provide Wi-Fi and Bluetooth LE connectivity to another micro-controller or microprocessor.
ESP32-C3 targets the most common and practical use-cases for connected devices. Espressif continues to build solutions that will address additional use-cases. In doing so, the company always takes community feedback into serious consideration. Espressif goes out of its way to show its gratitude for all the support from its maker friends, partners, and customers.
