Summary
ESP32-C3 is a development board based on the ESP32-C3FN4 chip.
ESP32-C3FN4 is a 32-bit microprocessor based on RISC-V architecture. It is a very low-power and high-integration MCU system-level chip (SOC), integrating 2.4 GHz Wi-Fi and low-power Bluetooth (Bluetooth® LE) dual-mode wireless communication. Internal integration 4MB flash, contains SPI, I2C, UART, ADC, etc.
It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.
Main Features
- Microprocessor: ESP32-C3FN4 (RISC-V architecture 32-bit, main frequency up to 160 MHz)
- Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
- Onboard SH1.25-2 battery interface, integrated lithium battery management system(charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching);
- Integrated WiFi, Bluetooth two network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz PCBantenna;
- Integrated CH340K USB to serial port chip, convenient for program downloading, and debugging information printing;
- Support the Arduino development environment;
- With good RF circuit design and basic low-power design (sleep current: 10uA theoretically), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
