Take Your Aerospace Projects to Orbit with a Field-Tested, Wire-Free 1U CubeSat Architecture

Unlock the blueprint to a highly reliable, flight-validated nanosatellite platform. This premium 1U CubeSat Design Package delivers a complete, professional-grade hardware architecture structured specifically for high-density sensor telemetry, active attitude control, and advanced payload integration.

Engineered with a modern wire-free stacking architecture, this design eliminates fragile wiring harnesses by utilizing high-density mezzanine connectors and flexible printed circuit (FPC) cables. It is the ultimate plug-and-play foundation for universities, aerospace startups, research laboratories, and advanced embedded systems engineers looking to deploy or validate space-ready subsystems.

Why Choose This Architecture?

Zero-Wire Stacking Topology: Features three custom-designed PCBs stacked over structural brass standoffs. Inter-board signals are bridged using parallel 36-pin FPC connectors with a 1-to-1 pin-to-trace mapping, isolating high-frequency switching noise and optimizing internal volume.
Ready-to-Scale M.2 Expansion: The main flight computer incorporates a high-density 67-position M.2 Key mezzanine interface. This allows developers to seamlessly snap in secondary experimental payloads, high-capacity data logging cards, or edge-compute hardware accelerators.
Proven 16 km Communication Range: This architecture has been experimentally validated under real-world conditions, establishing robust, uncorrupted telemetry downlinks over a tested ground line-of-sight distance of 16 km.

Subsystem-by-Subsystem Specifications

1. Centralized On-Board Computer (OBC) & Navigation Hub

At the heart of the satellite is an ultra-capable command center designed for robust multi-tasking:

Processing Power: Powered by an 84 MHz 32-bit ARM Cortex-M3 microcontroller (ATSAM3X8E).
Sensor Fusion Array: Integrates a high-performance 9-axis BNO085 IMU with its own Cortex-M0+ sensor fusion coprocessor (delivering drift-free quaternion orientation vectors), alongside a secondary low-power 6-axis Bosch BMI270 IMU.
Environmental & Optical Sensing Suite: Fully populated with a Renesas HS3003 temperature/humidity sensor, a Lite-On LTR-390 UV and ambient light sensor, and an Avago APDS-9960 RGB color/proximity/gesture sensor.
Scientific Payload & Storage Ready: Integrates a dedicated 7-pin SPI camera payload connector and a microSD card socket for high-capacity local flight data logging.
On-Board Display & Indicators: Includes a native dot-matrix SSD1306 OLED screen for real-time ground debugging and a physical piezo buzzer.

2. Smart Electrical Power System (EPS)

An autonomous, self-monitoring energy backbone designed to harvest, protect, and regulate power:

Dedicated Control: Powered by an independent, low-power 8-bit AVR core (ATmega328P running at 8 MHz) which handles localized battery diagnostics.
Dual-Source Charging: Employs four independent solar panels, each routed to its own STMicroelectronics SPV1040TTR step-up switching regulator with a localized Maximum Power Point Tracking (MPPT) algorithm. It also features a USB Type-C ground-charging port powered by a Consonance CN3302 asynchronous boost battery charger.
Battery Chemistry Support: Designed for a 2S (two-series) 18650 Lithium-Ion battery array (nominal system voltage of 7.4V, 3000 mAh capacity).
Fine-Grained Telemetry: Features four high-side digital INA219 power monitors tracking real-time logic rail, payload rail, charging path, and discharging path currents with extreme accuracy over I2C.

3. Active 3-Axis Attitude Determination & Control System (ADCS)

Maintain spatial stability and execute precise orbital orientation maneuvers:

Custom Actuator Geometry: Features a planar, zero-remanence air-core Z-axis coil integrated parallel to the solar panels (307 turns, AWG30) and dual high-density X/Y-axis transverse iron-core cylindrical solenoids (2,679 turns, AWG32).
Uniform Driver Electronics: Powered by three Texas Instruments DRV8835 dual H-bridge motor drivers designed to restrict peak power dissipation to 1.50 W per active channel.
Highly Responsive Control: Linear scaling of magnetic dipole moments is handled via dynamic Pulse-Width Modulation (PWM) signals from the flight computer.

4. Double-Redundant Wireless Communications (COMMS)

Keep constant contact with your ground segment:

Dual-Band Transceivers: Configured with redundant Ebyte LoRa transceivers (supporting both 400 MHz and 900 MHz bands) utilizing impedance-matched 50 Ω microstrip transmission lines.
GPS Tracking: Houses a Quectel L80-M39 GNSS receiver module with an integrated patch antenna and a hardware 1-pulse-per-second (1PPS) LED lock indicator.
