ESP32-C3 Development Board Modules Super Mini 32-Bit Single-Core Processor ESP32 C3 16Pin Type-C with Expansion Module

Description

The ESP32C3SuperMini is an IoT 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 RF performance and supports IEEE 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 used as ADC pins. It supports four serial interfaces: UART, I2C and SPI. The board 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, low-power, cost-effective iot mini development board for low-power iot applications and wireless wearable applications.

Expansion Board Overview:

The ESP32-C3 SUPERMINI expansion board is specifically designed for the ESP32-C3 SUPERMINI development board. It addresses many

limitations of the ESP32C3 SUPERMINI development board.

* The expansion board allows for the connection of an external 3.7V lithium battery and supports charging the battery via USB.

* The green indicator light turns on during charging and turns off when the battery is fully charged.

* All 10 GPIO pins are extended, making it convenient for users to connect various sensors.

* The expansion board provides a better power supply solution, featuring two power outputs: VCC1 and VCC2.

* By default, VCC1 and VCC2 output 3.3V.

* If a higher voltage output is required, you can short the PCB (as shown in the image below). In this case, VCC1 and VCC2

will output the power supply voltage of 3.7V.

* The default factory setting uses a 0Ω resistor connected to 3.3V. To output 3.7V, remove the 0Ω resistor and bridge the

three solder pads with solder.

* VCC1 and VCC2 control the voltage output independently. You only need to modify the one you intend to use.

Expansion Board Specifications:

* Voltage: 3.7V

* External Interface: PH2.0

* Dimensions: 22.50 mm × 37.40 mm
