This repository is a hardware reference design collection for the LattePanda Mu compute module, an Intel N100/N305-based system-on-module (SoM). It provides complete electrical schematics, PCB layouts (KiCad 8/9), 3D mechanical models (STEP), and pinout definitions for designing custom carrier boards. The repository includes four reference carrier board designs: Full EVA Carrier (DFR1141), Lite Carrier (DFR1142, V1 and V2), GPU Carrier (DFR1144), and Mini Carrier (DFR1293). Each design contains hierarchical KiCad schematics for interfaces such as PCIe x4, HDMI, USB 3.0/2.0, M.2 Key E/M, Gigabit Ethernet, GPIO/I2C/UART, and fan/temperature control. It also supplies BIOS firmware binaries (default, SATA, and carrier-specific branches), Windows driver packages, and mechanical dimension drawings. The repository is not a software application; it is a hardware engineering resource for building embedded system carriers. The codebase consists entirely of EDA files, footprints, symbols, and configuration, with no executable software or data pipelines.
The LLM identified 3 files worth highlighting for reuse:
A custom KiCad symbol library defining the 260-pin LattePanda Mu compute module. Pins are grouped by interface (Audio, DDI, GPIO, HSIO, I2C, etc.) and include power flags. This symbol is required for any carrier board design and is reusable across projects. It demonstrates disciplined hierarchical symbol design for a complex SoM.
A reusable hierarchical subcircuit for fan control and NTC thermistor temperature sensing. Implements a 4-pin fan connector (PWM + tacho) with reverse-voltage protection (Schottky diode) and optional pull-ups. The design is parameterized with DNP components and solder jumpers, making it adaptable to different carrier boards. It demonstrates clean, modular hardware design patterns for thermal management.
An Excel spreadsheet documenting the full 260-pin DDR4 SODIMM edge connector pinout for the LattePanda Mu module. Includes signal names, voltage domains, and interface assignments. This is the authoritative electrical interface definition, directly usable for schematic capture and PCB layout, and can be parsed programmatically for validation or automation.
