Conrad Digital Thermometer Module With LED Display Kit 192147 Data Sheet

Solder now both the spindle-trimmer potentiometers in the circuit. 

P1 = 100 k 

P2 = 100 k 

 

 

Set the LED-displays in the 40-pin IC-socket. 

See to it that each of the decimal points are below. 

LD1 = D 350 PA, TDSR 5150, SL 1119, LTS 546 AP, 0S-516 HWA or the like 
LD2 = D 350 PA, TDSR 5150, SL 1119, LTS 546 AP, 0S-516 HWA or the like 
LD3 = D 350 PA, TDSR 5150, SL 1119, LTS 546 AP, 0S-516 HWA or the like 
LD4 = D 350 PA, TDSR 5150, SL 1119, LTS 546 AP, 0S-516 HWA or the like 

 

 

The integrated voltage regulator (after bending the contact pins) is now inserted in the 
openings provided and the contact pins are soldered on the soldering side. 

Pay attention to a short soldering time, so that the voltage regulator is not destroyed by 
overheating. 

IC3 = 7805 TO 220
