Espressif introduced the ESP32-C3-WROOM-02 system-on-chip past year with options between the onboard PCB antenna and the external antenna connector. Adafruit has taken the lead to unveil an ESP32-C3 based developer board supporting Wi-Fi and Bluetooth Low-Energy wireless communication. As an entry-level RISC-V development board, hardware is an ideal choice for a wide range of applications, from IoT, embedded systems, smart homes to even wearable electronics.
Let’s take a peek inside the ESP32-C3-WROOM-02 module featuring a 32-bit RISC-V-based single-core processor clocked up to a frequency of 160MHz. The highly integrated ESP32 module comes with embedded 4MB SPI flash storage, 384kB ROM, 400kB SRAM, and 8kB SRAM for RTC. A rich set of peripherals and high performance make the module a good choice for industrial automation with decent support for wireless connectivity.
