inspect out all the stuff crammed into a little swath of strip board. It’s got that characteristic look of a roll-your-own Arduino board, which is precisely what it is. [S. Erisman] shows you exactly how to develop your own copy of his YABBS; Yet one more Bare Bones Arduino (on Stripboard).
The strips of copper on the bottom of the substrate run perpendicular to the DIP chip as well as have been sliced in the middle. This greatly reduces the amount of jumpering that would have been required if utilizing protoboard. A few wires make the required connections between the two tooled SIL headers that comprise the chip socket. On the best hand side there a voltage regulator with smoothing caps. The left side holds the obligatory pin 13 LED, as well as the crystal oscillator can be glimpsed on the far side of the ATmega328.
Pin headers along either side of the board have been modified to enable for soldering from the wrong side of the plastic frames. note that there’s a three-pin hunk that breaks out the voltage regulator, as well as an ISP programming header sticking out the top to which those female jumper wires are connected.
Ringing in at as bit as $2-$4.75 a piece you’ll have no issue leaving this in a job for the long hall. We can’t state the exact same for a $30+ brand name unit.
