I wouldn’t know I haven’t received it yet
I hope someday when the processors actually ship that I love them. I ordered them 19 days ago and based on tracking they either haven’t been shipped or they are in a truck somewhere in Australia

Great Company, Great Choice of Electronics Components and Modules
I've been buying from Lonely Binary (through eBay and Amazon) for years. I found their products and packaging to be of the highest quality. After dealing with them as well, I have found them to be extremely helpful and supportive. I highly recommend them to every one. They are a great company, and infact, one of the best, to deal with. Thanks.

PhotResistor Sensor
Item was well packaged with postage details updated regularly. Was exactly what i needed and got my projected finished. Very Happy

Light Photoresistor Sensor
used with arduino
Works well. Has quite a lot of torque. I bought the 180 degree model and noticed that it's maximum positions aren't exactly +90deg and -90deg. It actually rotates slightly more than 180 degrees range. I'm not using this servo with an RC transmitter but directly giving it a PWM signal from an arduino. Maybe this is a common problem with all servos, had no real issues with it.

I think this sensor is fantastic. Took a while for me to get it setup but that was all my fault as I wired it to the wrong pin lol.
One thing I particularly liked was the lonely binary packaging it come in. Only disappointment was that the spine did not have the sensor name on it. I think it would be fantastic for storing them in the lab if all packages come like that and were spine labeled.

OLED 0.91" I2C Display
I bought a three pack of these OLED 0.91" I2C displays and they came with in a plastic hard case with complete instructions. I was very impressed with the quality and the packaging.
I have always been delighted with the products I have bought from Lonely Binary, and I will continue to be a repeat customer.

DS3231 RTC
Behaves as expected. Installed Li2032 battery. Time seems accurate. I have used the EEPROM with ESP32 in Arduino IDE with #include "uEEPROMLib.h" and it is good.

Low power mode 12.3 mA??
This seems high. I would expect about 25 microamps from datasheet
