Product Introduction:
The ESP32 C3 SuperMini is an loT mini development board based on the Espressif ESP32-C3 WiFi/
Bluetooth dual-mode chip. The ESP32-C3 is a 32-bit RISC-V CPU that contains the FPU (floating
point unit) for 32-bit single-precision operations with powerful computing power. It has excellent F
performance and supportsIEEE 802.11b /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 and
delicate form factor combined with a single-sided surface mount design. It is equipped with a
wealth of interfaces, with 11 digital I/ OS that can be used as PWM pins and 4 analog I/OS that can
be usedas ADC pins. It supports four serial interfaces: UART, I2C and SPI. The oard also has a
small reset button and a boot loader mode button.
Combined with the above features, the ESP32C3SuperMini is positioned as a high-performance, lowpower, cost-effective IoT mini development board for low-power IoT applications and wireless
wearable applications.

External power supply:
If external power supply is required, just connect the + level of the external power supply to the
position of 5V.GND connects to the negative terminal. (Support 3.3 - 6V power supply). Remember
that when connecting the external power supply, you cannot access USB. USB and external power
supply can only choose one.
CAUTION: When welding, please be careful not to short-circuit the positive
and negative electrodes, otherwise it will burn the battery and equipment.
