STK551U3A2A-E

STK551U3A2A-E is an STMicroelectronics evaluation kit (STK) built around a target ST device to enable quick evaluation and prototyping on a ready-made hardware board. It typically includes the development board with the target IC and onboard peripherals (I/O, analog/digital interfaces, power section, connectors), debugging/programming capabilities, and bundled software tools plus example firmware and documentation. Use it for rapid learning, feature validation, and benchmarking before integrating a design. To get started: install the vendor’s IDE and drivers, connect and power the board, load the demo code or your project, and run the demonstrations. For exact specifications (target device family, interfaces, memory, clock options) and detailed setup, consult the official product page, datasheet, and user guide.

Manufacturer: SANYO (SANYO Electric Co., Ltd.).
What kind of company: SANYO was a Japanese electronics manufacturer that made consumer electronics and electronic components, including semiconductor devices and hybrid ICs (the STK series audio/power amplifier modules). Its semiconductor operations were later absorbed into other companies (e.g., ON Semiconductor).
