    SB030092024 – WIFI SCHEMATIC BLOCK

      ESP32-C3-WROOM-02 — RF TXRX MOD BT WIFI PCB TH SMD

      SKU: SB030092024 Category:

      This schematic block features the ESP32‑C3‑WROOM‑02, a fully integrated wireless module combining a RISC-V microcontroller core with 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) connectivity. Designed for compact, connected embedded systems, this module integrates a crystal oscillator, power management circuitry, and 4 MB SPI flash in a small SMD footprint.

      The module supports rich peripheral connectivity (GPIO, SPI, I²C, UART, I²S, remote control peripheral, PWM, ADC, and more) and includes built-in USB-Serial/JTAG for programming and debugging. With secure-boot and flash-encryption capabilities available at the SoC level, it’s suitable for secure IoT, smart home, and industrial automation designs.

      Key Features:

      • RISC‑V single-core MCU, up to 160 MHz
      • 384 KB ROM, 400 KB SRAM, 8 KB RTC SRAM
      • 4 MB SPI‑flash on module for application storage
      • Wi‑Fi: IEEE 802.11 b/g/n, 2.4 GHz, 1×1, up to 150 Mb/s
      • Bluetooth LE: Bluetooth 5.0, support for long range and mesh
      • On‑board PCB antenna (for this version)
      • Wide I/O support: GPIO, SPI, I²C, UART, I²S, PWM, ADC, watchdog, remote control, and CAN-like TWAI
      • USB Serial / JTAG interface built into module
      • Operating voltage: 3.0 V to 3.6 V
      • Operating temperature options: –40 °C to +85 °C (standard), and –40 °C to +105 °C (high-temp variant)
      • Power-saving modes: deep sleep, light sleep with µA-level consumption
      • Security: supports secure boot and flash encryption (AES) via the ESP32-C3 SoC

      Typical Applications:

      • Smart home & IoT devices with Wi-Fi and BLE requirements
      • Battery or USB-powered connected sensors
      • Industrial automation & control nodes
      • Environmental monitoring and telemetry
      • Connected wearables or health devices
      • Edge-computing applications with wireless connectivity

      By integrating this Quickboards schematic block, engineers can expedite wireless product prototyping, reduce external component count, and rely on a secure, production-grade module optimized for modern IoT systems.
