MIKROE has announced that the latest release of its mikroSDK software development kit now supports the Renesas RA2E1 family of low-power Arm Cortex-M23 MCUs. These devices run at up to 48 MHz and offer up to 128 KB of code flash, 16 KB of SRAM, and 4 KB of data flash.

The update, mikroSDK 2.17.12, continues the multi-year MCU development tool support agreement between MIKROE and Renesas, which was signed in January 2026. Under that agreement, MIKROE will provide development tools for 500 of Renesas’ most widely used MCUs, along with support for future devices as they are released.
Renesas is also launching, for the first time, a Planet Debug remote board farm. This setup allows developers anywhere in the world to remotely debug code without needing to buy or maintain their own hardware.
mikroSDK is designed to make application code portable across different platforms and architectures with minimal changes. It brings together open-source libraries, a unified API, and development tools that help engineers get started quickly with cross-platform embedded applications, including Click board™ projects and embedded GUIs.
The new 2.17.12 release also adds AGT PWM mode support for Renesas devices and includes a Cortex-M23 interrupt priority fix that resolves UART receive issues on RA2 devices. On top of that, support has been expanded to include 270 additional MCUs and 12 new board packages.
Leadership Comments
Comments Nebojsa Matic, CEO of MIKROE: “mikroSDK is open-source, and it’s natively supported in our NECTO Studio IDE. It is also available on GitHub. The approach is: ‘Learn Once, Code Anywhere’. Use it with our mikroC compiler or any other C compiler. Thanks to its modular structure, mikroSDK drivers are possible to integrate with other SDKs (including Azure Sphere and GCC).”
