Raspberry Pi is a wonderful platform you can use to build and experiment with electronics. The IOT Weather Kit comes with everything you need to program with Python. It has an OLED display, buttons, pressure sensor, humidity & temperature sensor, and an air quality sensor.
This kit runs on the Pi 3 B+ with a 5V 2.5A power supply. You also get an open source tool to monitor, log and display data on the OLED display.
