GSAS Cables, Adapters & Power Supplies

GSAS provides a complete range of cables, power supplies, and accessories designed and tested for use with GSAS microprocessor trainer kits, development boards, and peripheral interface modules. Every cable and power supply is specified to match the electrical and mechanical requirements of GSAS hardware, ensuring reliable connections, correct voltage/current ratings, and proper pin-to-pin mapping. Using GSAS-supplied accessories eliminates the troubleshooting overhead that comes with sourcing generic cables and adapters, particularly in multi-station lab environments where consistency across setups is essential.

For institutions setting up new labs or expanding existing ones, GSAS offers these accessories individually or as part of complete lab deployment packages. The FRC (Flat Ribbon Cable) range covers the standard 26-core, 40-core, and 50-core connections used between trainer kits and peripheral modules, available in 1-foot and 4-foot lengths to accommodate different bench layouts. Power supplies range from compact switch-mode adapters for single-board setups to multi-output bench supplies that power the trainer and all connected peripherals from a single unit. All accessories are available from stock for immediate dispatch.
