Note: Most (pretty sure all) of the stuff listed here is obsolete but could still be useful for playing around or if you want a cheap entry point to learn about creating embedded systems. I am willing to break it up if you really don't need everything.
That said, here's what this contains:
2x RX63N Demonstration Kit
The Renesas RX63N Demonstration Kit (RDK), also known as the Renesas Starter Kit+ for RX63N (YRDKRX63N), is a comprehensive evaluation board designed for the Renesas 32-bit RX63N microcontroller, providing engineers with a powerful, user-friendly platform to quickly develop and test applications, featuring an integrated debugger (J-Link), numerous peripherals like Ethernet, CAN, USB, and an LCD, and comes with sample code and development tools for rapid prototyping.
RL78/14 Demonstration Kit
The Renesas RL78/G14 Demonstration Kit (RDK) is a comprehensive hardware and software platform for evaluating and developing applications with Renesas' RL78/G14 microcontrollers, featuring an integrated debugger (like the TK Debugger or E1 emulator), various peripherals (LCD, audio, sensors, Wi-Fi), and development tools (e2 studio, IAR Embedded Workbench) for quick prototyping of products like home appliances, security systems, and motor controllers
2x SK-S7G2 Starter Kit
The Renesas SK-S7G2 Starter Kit is a low-cost development board designed for the Renesas Synergy S7G2 MCU, offering an entry point to the Synergy Platform for IoT and industrial applications, featuring an ARM Cortex-M4 core, Ethernet, USB, CAN, BLE, a 2.4" touch LCD, Arduino/Pmod expansion, and full access to the Synergy Software Package (SSP) and IDE tools like e2 studio for rapid prototyping and HMI development.
PE-HMI1 HMI Product Example
The Renesas PE-HMI1 Product Example is a development board showcasing a connected Human-Machine Interface (HMI) using Renesas Synergy S7G2 MCU, featuring a 7" capacitive touch display, Wi-Fi, Ethernet, and GUIX Studio for rich graphical applications like thermostats and weather apps, demonstrating real-world HMI design with full hardware/software documentation for developers to adapt for industrial IoT, automotive, or appliance products.
2x TMS320-XDS100-V3 - USB XDS100 V3 JTAG DEBUGGER DEVELOPMENT BOARD
The TMS320-XDS100-V3 is a low-cost, USB-powered JTAG emulator from Olimex, designed to debug Texas Instruments (TI) DSPs and ARM processors, acting as an interface between a PC running Code Composer Studio (CCS) and the target device for programming, emulation, and debugging (breakpoints, memory viewing). It's a hardware implementation of TI's XDS100v3 reference design, supporting various TI families (C28xx, C54xx, C674x, ARM Cortex) via multiple standard JTAG connectors and powered entirely by USB.
IAR Systems IAR Embedded Workbench
The IAR Systems IAR Embedded Workbench is a comprehensive Integrated Development Environment (IDE) and toolchain for building, debugging, and analyzing embedded software for various microcontrollers (MCUs) and processors, featuring a highly optimizing C/C++ compiler, advanced C-SPY debugger, project management, and analysis tools for efficient, reliable code. It streamlines development for architectures like ARM, RISC-V, and MSP430, supporting modern workflows and safety/security compliance.
There are also a couple of other odds and ends but I figured this listing was long enough.
