MIKROE has announced that the latest version of its mikroSDK software development kit now supports the Renesas RA2E1 family of low-power, Arm Cortex-M23 MCUs that operate at up to 48MHz with up to 128KB code flash, 16KB SRAM, and 4KB data flash.
mikroSDK 2.17.12 continues the multi-year MCU development tool support agreement between MIKROE and Renesas, signed in January 2026, which commits MIKROE to providing development tools for 500 of Renesas’ most popular MCUs, plus upcoming new releases. Renesas is also establishing, for the first time, a ‘Planet Debug’ remote board farm, which enables developers anywhere in the world to remotely debug code without having to invest in any hardware.
mikroSDK makes application code portable and reusable on many different platforms and architectures, with virtually no code changes. It is a collection of open-source software libraries with unified API and software development tools. Everything you need to start developing and prototyping cross-platform embedded applications, including Click board applications and GUIs for embedded devices.
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).”
The new version of mikroSDK 2.17.12 also includes AGT PWM mode support for Renesas devices and a Cortex-M23 interrupt priority fix, resolving UART receive issues on RA2 devices. Support for 270 more MCUs and 12 new board packages has also been added.
