# Code Examples

Ready-to-use MQTT-based examples for different platforms and environments.

* [**STM32Cube MQTT Client**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/tree/main/STM32F407_PPPoS_MQTT) - a FreeRTOS-based implementation for STM32 microcontrollers using generic AT command-based cellular modems like SIM7000
* [**Python 3** ](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/Python3/README.md)- suitable for use on Single Board Computers (SBCs) like `Raspberry Pi` and some Industrial IoT gateways
* [**MicroPython**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/MicroPython/README.md) - a fun and easy way of creating the device firmware
* [**Arduino / PlatformIO**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/Arduino_Blynk_MQTT/README.md) - a pre-configured project that supports over 15 connectivity-enabled boards, including the `Espressif ESP32`, `Raspberry Pi Pico W`, `Nano 33 IoT`, `Nano RP2040 Connect`, `UNO R4 WiFi`, `Seeed Wio Terminal`, etc.
* [**Plain C**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/C_libmosquitto/README.md) with the `Mosquitto` library - tailored for advanced use cases needing high performance, compact size, or system-level integration
* [**Lua**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/Lua_OpenWrt/README.md) - ready for deployment on `OpenWrt`-based routers and SBCs like `Onion Omega2`
* [**HTML5 / JavaScript**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/HTML5_WebSocket/README.md) - thanks to the `WebSocket` technology, this example can be used directly from the browser[**‍**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/ESP-IDF-Cellular/README.md)
* [**ESP-IDF Cellular**](https://github.com/Blynk-Technologies/Blynk-MQTT-Samples/blob/main/ESP-IDF-Cellular/README.md) - for Espressif ESP32 devices with a cellular modem
