Low Cost Renesas Target Boards for RX MCUs are Designed for Home Appliances, Building & Industrial Automation

Renesas Electronics has announced three new Target Boards for the RX65N, RX130 and RX231 32-bit Microcontroller (MCU) groups designed for home appliance, building and industrial automation applications.

Each board has minimal features with an on-chip debugger, a mini USB port, the micro-controller, and through-hole pin headers providing access to all MCU signals. This design allows to access all MCU features while keeping the price below $30.
