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.

如果需要外部供电只需将外部电源+级接入5V的位置，GND接负极。（支持3.3～6V电源）。切记连接外部电源的时候，无法接入USB，USB和外部供电只能选择一个。

注意

焊接时请注意不要使正负极短路，烧坏电池和设备。

如果想使用外置天线，可以按照一下图片外接外置天线。

您需要准备以下内容：

1 个ESP32C3SuperMini

1 台电脑

1 根 USB Type-C数据线

提示

有些USB线只能供电，不能传输数据。如果您没有 USB 线或者不知道您的 USB 线是否可以传输数据，可以购买Type-c数据线open in new window

• 步骤 1.通过USB Type-C数据线将ESP32C3SuperMini连接到计算机

• 步骤1.根据您的操作系统下载并安装最新版本的Arduino IDE

{{https://www.nologo.tech/assets/img/arduino/other/ArduinoIDE.png?nolink&}}open in new window

如果下载缓慢可以在国内Arduino社区下载ArduinoIDE下载地址open in new window

步骤 2.启动 Arduino 应用程序

步骤 3.将 ESP32 板包添加到 Arduino IDE

导航到File > Preferences ，然后使用以下 url 填写“Additional Boards Manager 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。
