Now we solder in the 5V switching regulator, the DC socket and 2 pin headers
Attention, it has to be a switching regulator , a normal 7805 gets too hot !
K5 is used to connect a power switch and must be bridged
K4 is later used for additional functions .
R78-E5.0-05, 12V DC,
header K4,K5
IC3 =R78-E5.0-05 = 5 Volt
K6= DC Plug
1x2 header K5 Power SW
2x3 header K4
-through hole
Recom switching power
regulator 5Volt
With this, we are done with the back of the board for now. The remaining components will
be soldered in at the very end, otherwise the soldering of some parts may not be easy.
