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.
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.
