The Enclosure Circuit Board has pre-cut strips. The convenient ProtoBoard pattern provides an easy way to connect parts while maximizing usable board area. It also provides an easy way to connect parts on a high-quality, single-sided FR4 glass-epoxy circuit board.
The Enclosure Circuit Board is made of aluminum alloy as the material of various shell. With high flexibility, depth can be arbitrary cutting, general internal circuit board slot, as long as the circuit board can be inserted directly, no need to be fixed, the convenience of other types of shell is incomparable. Aluminum shell using a die-casting technology, with waterproof and explosion-proof characteristics.
