Have a number of questions but let me start with this one: Is the Pi3 Model B an improved/faster version of Pi 3? I'm looking at Pi3s for sale on walmart.com from a few vendors (Viaboot, ZiggyMemory, VILROS) and see different options in their kits. One includes heatsinks, another a fan, if heat is an issue which of these options is better? One vendor (EEEKit) only sells kits and not Pi3. Looking at their kit wonder what the advantage is because it's got open sides, maybe for heat dispersion (https://www.walmart.com/ip/EEEKit-for-Raspberry-Pi-3-Model-B-Sliced-9-Layers-Case-Box-Cooling-Fan-SanDisk-16GB-Memory-Card-HDMI-Cable/113846451)? Anyway, have learned from research that Pi 3 is a 1GB motherboard, thought I saw 2GB somewhere, but did read that swapping can emulate more RAM. Here's some more Walmart links, if anyone has some recommendations (that I won't hold you responsible for) for best of these to purchase, please advise me. These all have the closed case and purchasing from Walmart just because have a gift card from there (will include descriptions vs links): Low price, heatsinks, but no HDMI cable Raspberry Pi 3 Model B Basic Starter Kit--Black Case Edition
This case kit (no motherboard) is $10.97. Would go well with motherboard and power supply only EEEKit 3in1 Kit for Raspberry Pi 3 Model B,Transparent 6-layer Case Box w/ Cooling Fan+Aluminum Heatsink+HDMI Cable
Anyway, appreciate any suggestions on all of the above.
