Particle Photon Development Board (Support WiFi & BLE)

Photon 2 Development Board is a Wi‑Fi and Bluetooth enabled microcontroller platform designed for rapid IoT prototyping and connected product development. The compact networking module integrates the Realtek RTL8721DM MCU with dual‑band 2.4 GHz and 5 GHz wireless connectivity, offering significantly expanded RAM and flash resources compared with earlier Photon‑series hardware. A Feather‑compatible form factor simplifies integration with existing expansion ecosystems while supporting migration toward surface‑mount production modules. This wireless IoT development board enables reliable cloud connectivity, advanced edge processing, and scalable connected applications across smart devices, automation systems, and prototyping environments compatible with Arduino style workflows.

Dual‑Band Wi‑Fi and BLE Connectivity

This IoT connectivity board supports 802.11a/b/g/n wireless networking across both 2.4 GHz and 5 GHz bands, enabling flexible deployment in environments with congested radio spectrum. An integrated PCB antenna ensures straightforward installation, while a built‑in U.FL connector enables external antenna attachment for improved signal coverage. BLE 5 support shares the same antenna system, allowing efficient wireless communication with mobile devices, sensors, and gateways in compact embedded systems.

High‑Performance Realtek RTL8721DM MCU

An ARM Cortex‑M33 processor running at 200 MHz provides strong computational capability for IoT applications requiring local data processing, communication management, and peripheral control. The embedded architecture supports complex firmware, real‑time device management, and advanced networking tasks. This microcontroller development platform suits connected prototypes, embedded gateways, and intelligent edge devices that require higher processing capability than traditional entry‑level MCU boards.

Large Memory for Complex Applications

Expanded memory resources enable significantly larger and more capable firmware projects. Up to 2048 KB user application size supports advanced networking stacks and complex device logic, while 3072 KB RAM provides ample runtime resources for buffering, encryption, and multi‑task operations. An additional 2 MB flash file system enables local data storage, configuration management, and log recording for connected IoT hardware and edge computing applications.

Typical deployments include smart home devices, wireless sensor networks, cloud‑connected monitoring equipment, and embedded control systems. The compact networking controller also fits well in educational prototyping, rapid IoT product development, and scalable hardware designs transitioning from development boards to surface‑mount production modules.
