Limrose I.C. Patchboards







Limrose's family of low-cost Patchboard Systems will save you time and money over and over again. These solderless breadboards will work with TTL. CMOS, Linear and other integrated circuits for teaching logic and development work. All Patchboards are available with or without internal power supplies.

These robust units will last for years and are very easy to use. ICs are plugged into high reliability sockets and discreet devices mounted on inexpensive plug-in adaptors. Interconnections are made using Limrose's unique and proven solderless patch leads and 1mm gold-plated terminal pins. Sub-systems such as memory boards and smaller breadboards can be plugged into PCB sockets. Several boards can be used together for larger projects. The Advanced Patchboard MPT0026 has been specially designed for use with Limrose's Microtutor and will accept compatible RAM, Analog and Digital I/O Boards.
