The Renesas Starter Kit for RX210 (B Mask) is intended as a user-friendly introductory and evaluation tool for the RX210 microcontroller. The board also provides a useful platform for evaluating the Renesas suite of development tools for coding and debugging, using High-performance Embedded Workshop. You can use the Renesas Starter Kit for RX210 (B Mask) in CubeSuite+.

The purpose of the board is to enable the user to evaluate the capabilities of the device and its peripherals by giving the user a simple platform on which code can be run only minutes from opening box. It can also prove an invaluable tool in development by providing a useful test platform for code already debugged using one of our more powerful emulation tools.

About the bundled emulator

We have already discontinued production of the E1 emulator due to components of the product having reached their EOL (end of life, i.e. end of production). Please click on the following link to confirm the details and our successor products.
