The first test was to measure the current consumption

The first test was made to check the consumption of the components Surface Mount. After having installed the components Surfaces Mount, the resistances, the two diodes, two electrolytic capacitors and the regulator. It was necessary to check the current consumption. To minimize the problems, it is preferable to check the components one by one.

Checking of the condensers

The value of this condenser is 100nF or 0.1uF

The PCB is ready for the first test

The circuit must be tested with a 9 battery

Ready to apply the current

The current is 14.07mA all receivers should be in that range
