Review on 10PCS OSOYOO Obstacle Avoidance Sensor Kit with IR Transmitting, Receiving Tube, and Photoelectric Switch for Arduino, Raspberry PI 4, 3 Model B - Ideal for Smart Cars and Robots by Pat Peoples
Troubleshooting
These boards have a 100 ohm current limiting resistor. Assuming a 1.2V, 20mA IR LED, a 190Ω resistor is required when 5V VCC and 105Ω at 3.3V VCC. This is why such a high failure rate is too much current for an LED at 5V. Solution: Either use 3.3V VCC or replace the 100 ohm resistor (marked 101 on the resistor) with a 200 ohm one -Resistance. I did the latter and the LED lived for 4 days while the original died after one day.
