ESP32-C3Mini

ESP32C3SuperMini is an IoT mini development board based on the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-V CPU, including FPU (Floating Point Unit), which can perform 32-bit single-precision operations and has powerful computing capabilities. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small form factor combined with a single-sided surface mount design. It is equipped with rich interfaces, with 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins. It supports four serial interfaces including UART, I2C and SPI. Also on the board is a small reset button and a bootloader mode button.Based on the above features, ESP32C3SuperMini is positioned as a high-performance, low-power, and cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable applications.

If external power supply is required, just connect the + stage of the external power supply to the 5V position and GND to the negative pole. (support 3.3 ~ 6V power supply). Remember that when connecting to an external power supply, USB cannot be connected, and you can only choose between USB and external power supply.

Notice

When welding, please be careful not to short-circuit the positive and negative poles, which may burn the battery and equipment.

If you want to use an external antenna, you can connect an external antenna according to the picture below.

You need to prepare the following:

1 ESP32C3SuperMini

1 computer

1 x USB Type-C data cable

hint

Some USB cables can only provide power and cannot transfer data. If you don't have a USB cable or don't know if your USB cable can transfer data, you can buy a Type-c cableopen in new window

• Step 1. Connect ESP32C3SuperMini to computer via USB Type-C data cable

• Step 1. Download and install the latest version of Arduino IDE according to your operating system

Step 2. Launch the Arduino application

Step 3. Add the ESP32 board package to the Arduino IDE

Navigate to File > Preferences and fill in the “Additional Boards Manager URL” with the following url:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

导航到Tools > Board > Boards Manager… ，在搜索框中输入关键字“ esp32 ”，选择最新版本的esp32并安装它。

导航到工具 > 开发板 > ESP32 Arduino并选择“ ESP32C3 Dev Module ”。板的列表有点长，你需要滚动到底部才能到达它。

导航到“工具”>“端口”，然后选择所连接的 ESP32C3SuperMini 的串口名称。这可能是 COM3 或更高版本（COM1和COM2通常保留用于硬件串行端口）。

步骤1.将以下代码复制到Arduino IDE

''// define led according to pin diagram
int led = 8;

void setup() {
  // initialize digital pin led as an output
  pinMode(led, OUTPUT);
}

void loop() {
  digitalWrite(led, HIGH);   // turn the LED on
  delay(1000);   // wait for a second
  digitalWrite(led, LOW);    // turn the LED off
  delay(1000);               // wait for a second
}

''

上传后，您将看到板子上的LED 闪烁，每次闪烁之间有 1 秒的延迟。
