Frequently Asked Questions
What are the core processing, memory, and wireless specifications of the ESP32-C3-MINI-1-N4 module?
The ESP32-C3-MINI-1-N4 is a compact Wi-Fi and Bluetooth Low Energy (Bluetooth® 5) module based on the ESP32-C3 SoC. It features a 32-bit RISC-V single-core processor running at up to 160 MHz, with 384 KB ROM, 400 KB SRAM (including 16 KB dedicated to cache), 8 KB RTC SRAM, and an integrated 4 MB SPI flash. The module supports IEEE 802.11 b/g/n Wi-Fi operating in the 2.4 GHz band and Bluetooth LE 5 with Bluetooth Mesh support. The ESP32-C3-MINI-1-N4 uses an onboard PCB antenna for wireless communication. Depending on the Wi-Fi data rate and operating mode, the typical transmit output power is up to 20.5 dBm (802.11b at 1 Mbps or 11 Mbps).
Which peripherals are supported by the ESP32-C3-MINI-1-N4?
The ESP32-C3-MINI-1-N4 provides a wide range of integrated peripherals, including UART, SPI, I2C, I2S, USB Serial/JTAG, LED PWM, remote control (RMT), TWAI® (CAN 2.0 compatible), SAR ADC, temperature sensor, general-purpose timers, watchdog timers, and up to 15 GPIOs. The module operates from a 3.0 V to 3.6 V supply and is suitable for embedded wireless applications requiring standard communication and control interfaces.
What are the power consumption characteristics and operating limits of the ESP32-C3-MINI-1-N4?
The ESP32-C3-MINI-1-N4 operates over an ambient temperature range of -40°C to +85°C and requires a 3.0 V to 3.6 V supply. Power consumption varies with the operating mode, including Active, Modem-sleep, Light-sleep, and Deep-sleep. During active Wi-Fi operation, typical peak current ranges from approximately 290 mA to 350 mA depending on the transmission mode, while receive current is typically 82–84 mA. In low-power operation, typical current consumption is approximately 130 µA in Light-sleep and 5 µA in Deep-sleep when using the RTC timer and RTC memory.
