Development board without soldering 830pin 165x55mm

Quick assembly and configuration of electronic circuit layouts without the use of soldering, using plug-in contacts.
Ready-made mock-up field for 700 contacts made of ABS plastic.
Board dimensions: 165 * 55 mm.
Central layout field 60+60 groups of 5 contacts in each group.
Edge power rails (100 pins) are divided into 6 groups, which makes it easy to combine them in various combinations.
Contact pitch=2.54mm.
Allows you to install lead-out components with lead diameters from 0.3 to 0.8 mm inclusive (29...20 AWG).
When prototyping, it is optimal to use jumpers made of cheap PKSV-2, PKSV-3, PKSV-4 "crossover" wire.
