ESP32C3 SuperMini is an IoT mini development board based on the Espressif ESP32C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-V CPU that includes an FPU (floating point unit) and can perform 32-bit single precision operations with powerful computing power.<br/><br/>3. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocol.<br/><br/>4. The board comes with an external antenna, which can enhance the signal strength of wireless applications.<br/><br/>5. It also has a compact and exquisite appearance combined with a single-sided surface mount design.<br/><br/>6. It is equipped with rich interfaces, including 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins.<br/><br/>7. It supports four serial interfaces: UART, I2C, and SPI.<br/><br/>There is also a small reset button and a boot loader mode button on the board.<br/><br/>9. ESP32-C3 SuperMini 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.<br/><br/><strong><span style="font-size:20px">Parameter Description:</span></strong><br/><br/>CPU: ESP32-C3, 32-bit RISC-V single core processor<br/><br/>Operating frequency: 160 MHz<br/><br/>Main frequency: 160M<br/><br/>SRAM: 400KB<br/><br/>ROM: 374KB<br/><br/>ADC: 2 * 12-bit SARADC, 6 channels<br/><br/>WiFi: 802.11b/g/n protocol, 2.4GHz, supports Station mode, SoftAP mode, SoftAP+Station mode, hybrid mode<br/><br/>Bluetooth: BT 5.0<br/><br/>Power consumption: Deep sleep power consumption is about 43 μ A<br/><br/>Rich on-chip resources: 400KB SRAM, 384KB ROM<br/><br/>Rich interfaces: 1xI2C, 1xSPI, 2xUART, 11xGPIO (PWM), 4xADC<br/><br/>Single sided components and surface mount design<br/><br/>Classic appearance, suitable for wearable devices and small projects<br/><br/>Reliable security features: Encryption hardware accelerator that supports AES-128/256, hashing, RSA, HMAC, digital signatures, and secure boot<br/><br/>On board LED blue light, GPIO8 pin<br/><br/>Size: 22.52x18mm<br/><br/><strong><span style="font-size:20px">Attention:</span></strong><br/><br/>If external power supply is needed, simply connect the external power supply+stage to the 5V position and connect the GND to the negative pole. (Supports 3.3-6V power supply). Remember that when connecting to an external power source, USB cannot be connected, and only one can be selected between USB and external power supply.<br/><br/>2. Please be careful not to short-circuit the positive and negative poles during welding, which may damage the battery and equipment.<br/><br/><strong><span style="font-size:20px">Instructions for use:</span></strong><br/><br/>Enter download mode: Press and hold the BOOT button on ESP32C3, then press the RESET button, release the RESET button, and then release the BOOT button. At this time, ESP32C3 will enter download mode. (Every time you connect, you need to re-enter the download mode. Sometimes when you press it once, the unstable port will disconnect, which can be determined by the sound recognized by the port.)<br/><br/><strong><span style="font-size:20px">Introduction to Expansion Board:</span></strong><br/><br/>The ESP32-C3 Supermini expansion board is a specially designed expansion board for the ESP32-C3 supermini development board. It compensates for many shortcomings of the ESP32C3 Supermini development board. The expansion board can be used to connect a 3.7V lithium battery externally, supporting charging the lithium battery through USB. When charging, the green indicator light lights up. When the green indicator light goes off, the lithium battery is fully charged, and the expansion leads out all IO ports, making it convenient for users to save various sensors.<br/><br/>The ESP32-C3 Supermini expansion board provides users with a better power supply solution, with two power supply options available: VCC1 and VCC2. The default output voltage of VCC1 and VCC2 is 3.3V. When you need to output a higher voltage, you can short circuit the PCB (as shown in the figure below). At this time, the output voltage of VCC1 and VCC2 is the power supply voltage of 3.7V. The default factory uses a 0R resistor connected to 3.3V. If you need to output 3.7V, simply remove the 0R resistor and short circuit the three solder pads with tin. VCC1 and VCC2 respectively control the voltage output, and you need to take one and process the other.<br/><br/><strong><span style="font-size:20px">Expansion board parameters:</span></strong><br/><br/>Voltage: 3.7V<br/><br/>External interface: PH2.0<br/><br/>Size: 37.4mm * 22.53mm<br/><br/><strong>Product List 1:</strong><br/><br/>1X development board<br/><br/>2X needle arrangement<br/><br/><strong>Product List 2:</strong><br/><br/>1X expansion board (product does not include batteries)<br/></div><br/></div></div><br/>
