1.2 Description
ESP32-C3-MINI-1 and ESP32-C3-MINI-1U are two general-purpose Wi-Fi and Bluetooth LE modules. The rich
set of peripherals and a small size make the two modules an ideal choice for smart homes, industrial automation,
health care, consumer electronics, etc.
The ordering information for the two modules is as follows:

ESP32-C3-MINI-1 comes with a PCB antenna. ESP32-C3-MINI-1U comes with a connector for an external
antenna. ESP32-C3-MINI-1 and ESP32-C3-MINI-1U have two variants:
• 85 °C version integrating the ESP32-C3FN4 chip and operating at –40 ~ 85 °C
• 105 °C version integrating the ESP32-C3FH4 chip and operating at –40 ~ 105 °C
The two variants only differ in chip integrated and ambient operating temperature. In this datasheet unless
otherwise stated, ESP32-C3-MINI-1 refers to both ESP32-C3-MINI-1-N4 and ESP32-C3-MINI-1-H4, whereas
ESP32-C3-MINI-1U refers to both ESP32-C3-MINI-1U-N4 and ESP32-C3-MINI-1U-H4.
The ESP32-C3FN4 chip and the ESP32-C3FH4 chip, both with a 4 MB flash, fall into the same category, namely
ESP32-C3 chip series. ESP32-C3 series of chips have a 32-bit RISC-V single-core processor. They integrate a
rich set of peripherals, ranging from UART, I2C, I2S, remote control peripheral, LED PWM controller, general DMA
controller, TWAI
®
controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also includes SPI, Dual
SPI and Quad SPI interfaces.
The ESP32-C3FN4 chip and the ESP32-C3FH4 chip vary only in the ambient temperature. For details, please
refer to Family Member Comparison in ESP32-C3 Series Datasheet.
