List of components and related markings on the PCB:
The components are placed on the PCB according to the markings below.
Note that for SMD components, the crescent coincides with the crescent already present on the integrated circuit or with the dot printed on the IC. This means that the ICs will be placed with the crescent to the left of the readable marking.
The two markings, illegible, are for the thermistor and the photoresistor. The thermistor is placed on the left, the photoresistor on the right. See the picture below.
