Review on 🔌 Sintron 40-Pin GPIO Extension Board + LCD 1602 + Micro Servo Motor Starter Kit - Compatible with Raspberry Pi 1 Models A+ and B+, Pi 2 Model B, Pi 3 Model B, and Pi Zero by Victor Ewing

Excellent kit. I've been using it for 3 months now. The cobbler didn't quite fit the breadboard's holes, so I had to separate the +/- ends from the rest of the breadboard. Also, the shoemaker's labels didn't seem to match those on the RPi Model B. Luckily I found a diagram online that solved this problem. I haven't found any helpful instructions on this kit, but all components work with equivalent manuals found online. I was able to get the LCD screen, LEDs, servo, relay, variable resistor (button), diode, buzzer, and transistors working just by googling how to use each item with a Raspberry Pi. I didn't bother with the ambient light sensor or anything else that wasn't mentioned.
