This protobloc 2A (breadboard h21b) features 4 rows of 50 interconnected sockets suitable for use as power supply rails. All positions are clearly defined on an alphanumeric grid.
The ABS polymer board is mounted onto a rigid base plate complete with three 4mm terminals in red, black and green for power connections. A mounting bracket, which clips into the base, is also provided to accept a variety of components including switches and potentiometers, etc.
Q. 1, What is the spacing of the holes ?
2. What SWG can the holes Take ?
3. Is the board suitable for DIL IC's ?
4 I assume this is a clip in type board ie no soldering am I correct ?
A. Hi Kenneth. Thank you for your question. Hole pitch is 2.54mm (0.1”). It usually works well with 0.6mm solid wire such as 01-0300. It will take DIL ICs. It is a push in type – no soldering.
