5PCS ESP32-C3 MINI Development Board ESP32 Super Mini Development Board WiFi Bluetooth Expansion Boa
1. ESP32C3 SUPERMINI is an I0T mini development board based on the ESP32-C3 WIFI/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-VCPU that includes an FPU (floating point unit) that can perform 32-bit single-precision operations and has powerful computing power. It has excellent performance and supports IEEE 802.11 B/G WIFI and Bluetooth 5 (LE) protocols.
2. The board comes with an external antenna to enhance the signal strength of wireless applications. It also has a small and exquisite appearance combined with a single-sided mount design. It is equipped with rich interfaces, with 11 digital I/O that can be used as PWM pins and 4 analog I/O that can be used as ADC pins.
3. It supports four serial interfaces such as UART, and SPI. There is also a small reset button and a bootloader mode button on the board. 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.
4. Note: If external power supply is required, just connect the external power supply + level to the 5V position and GND to the negative pole. (Support 3.3-6V power supply). Remember that when connecting an external power supply, you cannot connect to USB. You can only choose one between USB and external power supply. Be careful not to short-circuit the positive and negative poles during welding to burn the battery and equipment.
5. Instructions: Enter download mode: and hold the BOOT button of ESP32C3, then the RESET button, release the RESET button, and then release the BOOT button. At this time, ESP32C3 enter download mode. (You need to re-enter download mode every time you connect. Sometimes, if you it once, the port be unstable and disconnected. You can judge it by the port recognition sound)
