Supported Hardware

List of hardware and development boards that work with Blynk.

There are five ways to get your devices connected to the Blynk Cloud:

Blynk Library

An easy to use and portable C++ library, pre-configured to work with hundreds of development boards.

The library implements a streaming connection protocol (i.e. the device stays always connected to the cloud), that allows for a low latency, bi-directional communication.

Try Quickstart flow and make sure to explore Blynk Library documentation afterwards.

Blynk.Edgent

Blynk.Edgent is a packaged solution that allows you to easily connect devices to Blynk and take advantage of all its advanced features, including:

• Blynk.Library API

• Blynk.Inject (dynamic device credentials provisioning)

• Blynk.Air (firmware OTA updates)

If your hardware supports Blynk.Edgent, we recommend using this flow at all times.

Blynk.NCP

Blynk provides a versatile software stack for Network Co-Processors (NCPs), which are dedicated connectivity chips or modules.

NCP handles Blynk.Cloud connectivity (WiFi, Ethernet, Cellular), offloading this task from the main device's MCU. The main MCU operates with a lightweight client library, communicating with the NCP via UART or SPI. This setup offers rapid and high-quality integration, making it ideal for retrofitting scenarios.

To get started, check our firmware examples to connect a dual-MCU board or design your own device by incorporating an NCP module.

HTTP(s) API

This is a standard communication protocol suitable for any internet-connected device.

It allows the device to connect to the cloud periodically to transfer data. Additionally, it supports sending timestamped data in batches, a feature especially beneficial for cellular devices.

You can find more guidance in HTTP(s) API documentation.

MQTT API

A secure, industry standard two-way communication protocol.

Supports authentication, updating data streams, widget properties, events, metadata, timezone/location information, OTA firmware updates and more.

Ideal for projects utilizing MQTT libraries, Node-RED and similar, or SDKs with MQTT support.

Works for integrating off-the-shelf MQTT-enabled gateways and other hardware directly into the Blynk environment.

Hardware that works with Blynk library or HTTPs API (using Static Tokens)

This is the easiest way to migrate from legacy Blynk projects. Just add BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME at the top of your firmware (prior to any includes), update your auth token and that's it. Read more about project migration.

Traffic optimization is usually required for cellular connections. Using realtime streaming protocols like Blynk or MQTT has benefits of interactive device updates, but it also requires device to stay "always connected", which significantly increases the traffic. Blynk recommends using HTTPS (batch) API for reporting telemetry and fetching DataStream values periodically in such scenarios. It will also help saving the battery.
