## 1. Product Overview 

ESP-C3-01M-Kit is a core development board developed based on ESP-C3-01 module. The development board continues the classic design of the NodeMCU development board, leading all I/Os to the headers on both sides, and developers can connect peripherals according to their needs. When using the breadboard for development and debugging, the standard headers on both sides can make the operation easier and more convenient. ESP-C3-01M is a Wi-Fi module. This module core processor ESP32-C3 is a Wi-Fi+ BLE combination of system-level chips (SoC), designed for various applications such as internet of things (IoT), mobile devices, wearable electronics, smart home, etc.

## ESP32-C3-01M-KIT 

ESP32-C3 with industry-leading low power and RF performance, supporting Wi-Fi IEEE802.11b/g/n agreements and BLE 5.0. ESP32-C3 chip is equipped with 32-bit RISC-V single-core processor, operating frequency up to 160 MHz. The chip is support to have secondary development without using other microcontrollers or processors. The chip has a built-in 400 KB SRAM ， 384 KB ROM ， 8KB RTC SRAM.Also, the chip support external Flash while it built-in 4Mbit Flash. ESP32-C3 chip supports a variety of low-power consumption working states, which can meet the power consumption requirements of various application scenarios. The chip's unique features such as fine clock gating function, dynamic voltage clock frequency adjustment function, and RF output power adjustable function can achieve the best balance between communication distance, communication speed and power consumption. ESP-C3-01M provides a wealth of peripheral interfaces, including UART, PWM, SPI, I2S, I2C, ADC, temperature sensor and there are 15 GPIOs. 

ESP-C3-01M has a variety of unique hardware safety mechanisms. The hardware encryption accelerator supports AES 、 SHA and RSA algorithm. Among them, RNG, HMAC and Digital Signature modules provide more security features. Other security features include flash encryption and se-cure boot signature verification, etc. The perfect security mechanism enables the chip to be perfectly applied to various encryption products. 

ESP-C3-01M module supports low-power Bluetooth ： Bluetooth5 ， Bluetooth mesh. 

Bluetooth rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps. Support broadcast extension, multi-broadcasting, channel selection.

## 6. Design Guidance 

## 6.1 Power supply 

- Recommend 5V voltage, peak current above 500m. 

- It is recommended to use LDO for power supply; if DC-DC is used, the ripple is recommended to be controlled within 30mV. 

- DC-DC the power supply circuit, it is suggested to reserve the position of output ripple can be optimized when the load changes greatly. 

- It is recommended to add ESD devices to the 5V power interface. 

## 6.2 Antenna layout requirements 

It is forbidden to place metal parts around the module antenna, away from high-frequency components.
