We built this board for makers who want a suction LFR without the mechanical complexity of building one from scratch. Instead of designing an acrylic chassis, sourcing standoffs, running wires between a controller PCB and a structural frame, then bolting an impeller housing somewhere it fits,you start with one flat board that already does all of that. The PCB is the structure. The impeller is integrated. The SMD work is done.
The Spirit PCB is a PCB-cum-chassis for suction line follower robots. The circuit board is the structural body. Motor mounts bolt directly to the board. The impeller system is mounted at center. There is no separate frame, no standoffs, no acrylic plate beneath it.

ARDUINO NANO TYPE-C
◘ The Spirit PCB is a monolithic, integrated PCB-cum-chassis designed to function simultaneously as the structural frame and the primary electronic platform of a high-speed suction line follower robot. By combining the airframe and robot controller into a single load-bearing PCB, it reduces overall mass, simplifies assembly and improves structural rigidity.
◘ The PCB supports an Arduino Nano (ATmega328P, 16 MHz, 5 V logic) and is configured with an onboard TB6612FNG dual H-bridge motor driver for standard N20 geared motors. User buttons, status LEDs, reverse-polarity protection, filter capacitors and supporting SMD circuitry are factory assembled, minimizing external wiring and simplifying system integration.
◘ Dedicated interfaces are provided for dual drive motors, an external impeller motor controller, an 8-channel analog sensor array, battery input and user peripherals. Independent logic, sensor and impeller power rails enable flexible power distribution while maintaining compatibility with high-speed suction line follower architectures.
◘ The PCB geometry is engineered for balanced mass distribution and structural efficiency. The impeller is positioned near the geometric center of the platform, motor mounts are integrated directly into the board, and the overall airframe minimizes unnecessary mass while maintaining the rigidity required for high-speed operation.
SOFTWARE AND PROCESSING
◘ The Spirit PCB is built as an open, programmable embedded platform optimized for real-time robotics applications. It provides developers with direct access to the ATmega328P microcontroller resources, enabling implementation of custom firmware for sensing, motion control and peripheral management.
◘ Developers can implement PID control, state-machine architectures, interrupt-driven routines and other embedded control algorithms according to application requirements. The platform supports both Arduino framework development and direct AVR register programming, allowing high-level application code to be combined with low-level hardware control where required.
◘ Hardware PWM, ADC and timer peripherals support deterministic motor control, stable analog sensor acquisition and precise timing operations. Time-critical functions may directly access the microcontroller registers, while the remaining application can continue using standard Arduino libraries.
◘ Whether developing educational projects, research prototypes or competition robots, the Spirit PCB provides a flexible hardware foundation for real-time embedded applications and custom robotics firmware.
