U1C61

U1C61 is a fictional designation that appears in teaching resources and case studies to illustrate embedded hardware design. It is not a real product, standard, or catalog item, and there is no official specification outside of its use in examples.

In the typical depiction, U1C61 is a compact single-board computer or microcontroller module intended for educational experiments in sensing and control. The imagined platform combines a 32-bit CPU core with moderate RAM and persistent storage, a selection of interfaces such as UART, I2C, SPI, GPIO, and a wireless transceiver. The design emphasizes modularity, with plug-in boards or shields that add sensors, actuators, or power management. A low-power sleep mode and a simple wake-up mechanism are commonly described to illustrate power budgeting in embedded systems.

Software and development for U1C61 are described as using mainstream compilers and open-source IDEs, with firmware written in C or C++ and sometimes a lightweight real-time operating system. The workflow typically covers hardware hookup, peripheral initialization, interrupt handling, and debugging in simulated or real hardware environments.

Applications of the fictitious U1C61 include classroom labs and online tutorials to demonstrate board-level architecture, hardware-software integration, and prototyping workflows. It is often used to teach topics such as peripheral interfacing, timing, and energy efficiency, providing a concrete example without relying on a specific real-world device.

Variants and status described in sources include different connector layouts and sensor suites (for example, U1C61-A and U1C61-B). Because U1C61 is fictional, there is no official maintenance or warranty, and real-world projects should rely on actual hardware and documented specifications.
