Electrical design and firmware: differential serial switching and radio-frequency detection
A board that switches RS-422 differential serial links with the logic implemented as FPGA firmware, and a unit that detects a radio-frequency signal and commands path switching with microcontroller firmware. Electrical design, board build, firmware design and development.
An electronic board that routes RS-422 serial links — differential transmission, used where the run is long or the environment electrically noisy — between different sources and destinations inside a test chain, for a space agency programme. The switching logic is implemented as FPGA firmware rather than hard-wired logic: one board covers several test configurations by reconfiguration rather than re-cabling, moving the variability from the bench into a file.
The second unit detects the presence and level of a radio-frequency signal and commands path switching accordingly, for a defence industrial group. Here the scope is engineering only: system electrical design and microcontroller firmware design and development, with no build — a contractual shape that documents how the company also sells design on its own.
Taken together, these are the supplies that reach the lowest level, the board and the firmware, and the pair that documents firmware capability explicitly.
