This is a board on which even your bigger project will fit. This breadboard consists of 3 base modules and 5 bus modules.
A base module consists of two columns of 5 x 64 connections with a 7.62 mm separation channel. A bus module consists of 4 sockets of 25 connected terminals spread over 4 rows.
In contrast to many low-cost breadboards, the spring contacts are durable and continue to work well even after multiple use. The contacts consist of an alloy of silver and nickel.
