Mingjiada Supply Espressif ESP32-C61-WROOM-1U-N8R2 Module | Wi-Fi 6 + BLE Wireless Communication Module

In today’s rapidly evolving landscape of the Internet of Things (IoT) and edge computing, selecting a wireless module that offers powerful performance, stable connectivity and ease of development is key to a product’s success. Espressif’s ESP32-C61-WROOM-1U-N8R2 general-purpose module, with its support for 2.4 GHz Wi-Fi 6 (802.11ax) and Bluetooth 5 (LE), as well as its rich resource allocation, has become the ideal choice for the smart home, industrial automation and consumer electronics sectors.

Shenzhen Mingjiada Electronics Co., Ltd. maintains a long-term stock of the ESP32-C61-WROOM-1U-N8R2 and simultaneously offers high-value cash buyback services for this model, as well as various IC chips and IoT modules, helping global customers safeguard production and revitalise assets.

I. Product Overview: Ushering in a New Era of Wi-Fi 6 IoT
The ESP32-C61-WROOM-1U-N8R2 is a high-performance, low-power wireless communication module launched by Espressif, specifically designed to meet the dual requirements of high concurrency, low latency and low power consumption for the next generation of smart devices. Built on the ESP32-C61 series chip, this module fully supports dual-mode wireless communication via 2.4 GHz Wi-Fi 6 (802.11ax) and Bluetooth Low Energy 5 (Bluetooth LE). It utilises an external antenna connector (I-PEX/U.FL socket), offering significant advantages in terms of wireless signal coverage and RF performance.

II. Core Hardware Architecture
2.1 Processor Core
The ESP32-C61-WROOM-1U-N8R2 is equipped with the Espressif ESP32-C61 series SoC, which integrates a 32-bit single-core RISC-V microprocessor with a maximum clock speed of 160 MHz. With 256 KB of ROM and 320 KB of SRAM built-in, it provides ample on-chip memory resources for system operation and protocol stack execution. The openness and flexibility of the RISC-V architecture, combined with Espressif’s mature ESP-IDF development framework, enable developers to rapidly complete the entire development process from prototype validation to mass production.

2.2 Memory Configuration
In the model suffix “N8R2” of the ESP32-C61-WROOM-1U-N8R2, “N” indicates an operating temperature range of -40°C to 85°C, making it suitable for the vast majority of industrial and consumer applications; “8” denotes 8 MB of Quad SPI Flash; “2” denotes 2 MB of stacked PSRAM. The stacked PSRAM, connected via the Quad SPI interface, supports a maximum operating frequency of 120 MHz, providing ample RAM expansion capacity for applications with moderate data processing requirements (such as smart devices with simple graphical interfaces and sensor data acquisition systems). The Quad SPI Flash ensures secure firmware storage and fast read performance, supporting OTA (Over-the-Air) firmware updates.

2.3 Antenna Interface
The ESP32-C61-WROOM-1U features an external antenna connector (I-PEX/U.FL socket) design, allowing users to freely select high-gain external antennas according to their specific application environment to enhance wireless communication range and signal penetration. Compared to the on-board PCB antenna version (WROOM-1), the WROOM-1U offers a more flexible RF design, making it particularly suitable for metal enclosures, long-range coverage, or other scenarios involving signal attenuation.

2.4 Electrical and Environmental Specifications (ESP32-C61-WROOM-1U-N8R2)
Dimensions: 18.0 × 19.2 × 3.2 mm
Operating voltage: 3.0 V to 3.6 V, typical 3.3 V
Operating temperature: -40°C to 85°C

III. Wireless Communication Features
3.1 Key Features of Wi-Fi 6
The ESP32-C61-WROOM-1U-N8R2 supports the Wi-Fi 6 (802.11ax) protocol in the 2.4 GHz band, operating in 20 MHz bandwidth mode, whilst remaining backwards compatible with the 802.11 b/g/n protocols. Its key technical features include:
OFDMA (Orthogonal Frequency Division Multiple Access): Supports both uplink and downlink OFDMA, allowing multiple devices to be served simultaneously on the same channel, significantly reducing network latency in multi-device connection scenarios and improving channel utilisation.
MU-MIMO (Multi-User Multiple Input Multiple Output): Supports downlink MU-MIMO, enhancing network capacity; particularly suitable for scenarios where gateway-type centralised devices communicate with multiple terminals simultaneously.
TWT (Target Wake Time): Enables devices to negotiate wake-up intervals with the AP, entering deep sleep during periods of inactivity, thereby significantly reducing power consumption and extending the battery life of battery-powered devices.

Data Rate: The maximum wireless data rate reaches 150 Mbps, fully meeting the data transmission bandwidth requirements of IoT devices.

3.2 Bluetooth 5 Features
The module integrates Bluetooth 5 (LE) wireless functionality, utilising low-energy Bluetooth technology, and offers the following key features:
Long Range: Enables long-range transmission via the Coded PHY.
High-Speed Transmission: Supports a 2 Mbps PHY for efficient data synchronisation.
Advertising Extensions: Supports enhanced advertising capabilities.
Bluetooth Mesh 1.1: Supports full-featured Bluetooth Mesh networking, meeting the requirements of multi-device collaboration and self-organising network applications.

IV. Extensive Peripherals and Interfaces
The ESP32-C61-WROOM-1U-N8R2 provides up to 23 programmable GPIO pins, supporting flexible peripheral expansion. Its integrated peripheral interfaces include, but are not limited to:
Communication Interfaces: SPI, UART, I2C, I2S, USB Serial/JTAG Controller
Control interfaces: LED PWM controller, SDIO slave controller
Analogue signal processing: SAR ADC, temperature sensor, analogue voltage comparator, power-down detector
Advanced features: Event Task Matrix (ETM) for automated system trigger coordination, general-purpose timer, system timer, watchdog timer, GDMA (General-Purpose DMA)
With a rich combination of GPIOs and peripherals, the ESP32-C61-WROOM-1U-N8R2 can flexibly adapt to the hardware control requirements of diverse IoT end devices, such as smart lighting, temperature and humidity sensing, motor control, and audio playback.
