PlatformIO Open Source May Updates
New boards and dev-kits, Support for the latest ESP-IDF, Updates for Espressif32, ST STM32 and mbed-enabled dev-platforms
Welcome to the May 2025 updates of PlatformIO Open Source professional collaborative platform for embedded development.
This month we received a lot of helpful feedback from our community, which let us identify the most important parts of our OSS ecosystem that required our attention, so there are plenty of updates pushed in this month that we hope you will like.
During May, we added support for the latest ESP-IDF, rolled out updates for several popular development platforms, fixed a lot of issues. Some of the key highlights include:
- ESP-IDF v5.4.1
- Espressif32 dev-platform v6.11
- ST STM32 dev-platform v19.2
- Arduino Core for mbed-enabled devices v4.3.1
ESP-IDF v5.4.1
We’re happy to announce updated support for the latest release of ESP-IDF v5.4.1 - the official development framework for the ESP32, ESP32-S and ESP32-C Series SoCs. It provides a self-sufficient SDK for any generic application development on these platforms, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys to big appliances and industrial devices.
Major enhancements in v5.4.1:
- Added config to enable/disable BLE channel assessment and ping procedure on ESP32
- Optimization of RX calibration for Wi-Fi in high-interference environments
- Added MALLOC_CAP_SIMD flag to allocate memory that is suitable for SIMD instructions
More information on project configuration for ESP-IDF can be found here.
