Overview

Pico-Sensor-Kit is a PICO entry-level sensor kit, including common sensors such as LED, buttons, and buzzers, which is easy for beginners to get started.
All-in-one design, all the modules are connected with PCB castellated holes, which is not needed to be soldered or wired anymore. Hence, you do not need to worry about the wiring. and it can provide you with an excellent programming experience.

Of course, you can separate these modules, and then connect them with the wires we provided, and these modules are easy to be integrated into your projects.

  • PS: Please pay attention to the sharp cuts and fragments when disassembling the modules.

FAQ

Question:I tried the "I2C1-OLED.py" example. The upper half of the display looks good but the bottom half contains noise or very garbled data.

 Answer:

The problem should be caused by the speed setting in the codes.
You can increase the speed and test again.
