Product FAQ

  • 1. 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).
  • 2. 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.
  • 3. 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.
  • 4. What PCB layout considerations apply to the ESP32-C3-MINI-1-N4?
    The ESP32-C3-MINI-1-N4 integrates an onboard PCB antenna. The module includes a defined antenna keep-out area, and the datasheet refers designers to the ESP32-C3 Hardware Design Guide for recommended module placement and antenna clearance on the host PCB to help maintain wireless performance.
  • 5. What applications is the ESP32-C3-MINI-1-N4 intended for?
    The ESP32-C3-MINI-1-N4 is a general-purpose Wi-Fi and Bluetooth Low Energy module intended for embedded wireless applications. Typical applications include smart home devices, industrial automation, healthcare equipment, consumer electronics, smart agriculture, POS terminals, service robots, audio devices, low-power IoT sensor hubs, and low-power IoT data loggers. According to the datasheet, the ESP32-C3-MINI-1-N4 variant is designated Not Recommended for New Design (NRND), and Espressif recommends the ESP32-C3-MINI-1-H4X variant for new designs.
