An electrical schematic is not just a drawing โ it is the core of the entire project. Everything that follows, from PCB layout to firmware to testing, relies on decisions made at this stage. A poor schematic does not become better on the board.
Our approach to schematic design starts with defining the system architecture. Before a single component is placed, we work out the block diagram: what functional blocks the device consists of, how they communicate, where the critical points are. Only then does the detailed work begin.
We work with the full spectrum of components and technologies. Microcontrollers of all architectures โ from simple 8-bit to 32-bit ARM Cortex cores. Programmable logic โ CPLD and FPGA for applications requiring parallel operations, deterministic timing, or high-speed signal processing. Power management โ linear regulators, switching converters, battery chargers, voltage supervisors. Communication interfaces โ UART, SPI, I2C, USB, Ethernet, CAN, RS-485, and wireless technologies.
Component selection is not only a technical task โ it is also a logistical one. Designing around a component that is unavailable or has a 52-week lead time is not a solution. Every selection is checked for availability at distributors, alternative sources are analysed, and where possible, approved substitutes are defined already during the design phase.
We pay particular attention to power design. The power tree โ the hierarchy of voltages and currents through the system โ is defined carefully, with current headroom, proper power sequencing where required, and protection circuits where critical. Power design errors are the most common cause of non-functional prototypes.
Similarly, every digital signal that crosses a voltage domain boundary, transitions between fast and slow domains, or carries sensitive data, is handled consciously โ with isolation, level shifters, or appropriate line drivers.
We deliver the schematic in whatever format the client can use โ PDF for review and archiving, native Altium format for further work if the client has their own team, or a neutral format by agreement. Along with the schematic comes an initial BOM list with selected components, references, and recommended distributors.
If the client comes with their own schematic โ no problem. We also offer schematic review and revision services, with a written report of findings and recommendations before moving into the PCB phase.
