Freenove Ultimate Starter Kit for Raspberry Pi 5 4 B 3 B+ 400 Zero 2 W, 962-Page Detailed Tutorial, Python C Java Scratch Processing Code, 223 Items, 128 Projects (Raspberry Pi NOT Included)

Just buy the whole kit with protective box, power unit and sd card. Also buy a micro sd card reader for pc or laptop if you don't have one onboard. Also practical: OTG adapter, micro HDMi adapter, LAN cable And if your 13 y/o wants to learn something about electrical engineering, there are GPIO breakout kits and video learning material out there. I would recommend a starter kit with some control elements and LED lights and stuff (see amazon link) https://eu.robotshop.com/products/adeept-raspberry-pi-gpio-breakout-kit https://www.amazon.com/dp/B06W54L7B5/ref=mp_s_a_1_1
