HDMI monitors may be a little difficult to come by? USB keyboard mice etc should be easier but you might have to concider including a USB hub. One idea to concider is bundling RPi and a cheap projector together with keyboard/mouse etc in a case, as proposed here[1] for use in India. I wouldn't get too hungup on the laser cut steel case I'm sure locally sourced alternatives could be used.

Re: [Hampshire] raspberry pi and educational software
Hi Roger, I'll give an anecdote. The Raspberry Pi runs a hardware-tweaked version of Linux and I was surprised at just how well it performs and what's installable from the repositories. I bought one out of curiosity then, after a machine failure, put it into my home networks as a DMZ and postfix mail host as a temporary fix. system, load with "w" was 0 0 0, even with anti-spam running. Oh; right; let's try anti-virus filtering, too. Still around 0 0 0. Wow. Later I also added a squid proxy ... system load still modest. It stopped being a temporary fix ... it's still there. I would suggest they get one and try it for their wanted purposes. I think they'll be pleasantly surprised at what it can do. https://tutorials-raspberrypi.de/ https://www.makershop.de/raspberry-pi https://www.raspberrypi.com https://thepihut.com/ In a hot climate the standard Pi may well want some heat-sinking.

The main limitations in these remote areas is POWER Only if they have enough power, is it worth adding more screens and other electronic equipment. You still need a screen and keyboard to program a Raspberry Pi. I have used a sharpened rod of iron, placed in a fire, to do soldering before.

Sounds like a fascinating and wholesome project! The whole Raspberry Pi web site is a valuable resource; they have a education landing page here: https://www.raspberrypi.org/teach/ The forums at https://www.raspberrypi.org/forums/ has a plethora of people discussing the Pi and its numerous uses.
