Supply And Recycle Espressif ESP32-C61-WROOM-1U-N8R8 2.4GHz Wi-Fi 6 + BLE 5 Dual-Mode Wireless Module
Shenzhen Mingjiada Electronics Co., Ltd. – We maintain a long-term stock of the ESP32-C61-WROOM-1U-N8R8 and the full range of Espressif chip modules, whilst offering high-value global buyback services for related stock components, providing customers with a one-stop, end-to-end service covering everything from component supply to inventory management.
The ESP32-C61-WROOM-1U-N8R8 is a 2.4 GHz Wi-Fi 6 + Bluetooth 5 (LE) dual-mode wireless module designed based on the Espressif ESP32-C61 series chip. This module features an external antenna connector (I-PEX/U.FL interface). Unlike the WROOM-1 version, which utilises an on-board PCB antenna, the U-series module design allows users to select external antennas according to their specific application environment, thereby achieving higher wireless signal coverage quality and RF flexibility.
The core advantage of the ESP32-C61-WROOM-1U-N8R8 lies in its large 8MB PSRAM capacity. Such a substantial amount of PSRAM is extremely rare among Wi-Fi 6 modules in this price range, enabling seamless support for complex protocol stacks, data caching, audio processing and lightweight UI/graphics processing, thereby resolving the performance bottlenecks caused by limited memory in traditional modules.
