I'm doing a replacement cost estimate for 4H STEM materials. We have a Google Making and Science activity kit that teaches conductivity with Arduino 101s, along with 9V battery hookups, breadboards, 104 capacitors, USB hookups, alligator clips, and breadboard jumper wires. I do not have any instructions for what the Arduinos are used for specifically. Which Arduino board should I list to replace the 101s?
There's also resistors with yellow, purple, orange, and brown lines on them included in the kit.
Are there any dependencies on the Arduino 101 specifically, for example lots of documentation, course material or hardware ad-ons (shields etc.) specifically for that board ?
Really you have to have a clear idea of what experiments, classwork etc. are going to be used in conjunction with the board for a meaningful recommendation. A very basic board but with extra hardware could also be an option. Another consideration in the choice of board may also be the availability of online simulators so students, who may not have the hardware at home, can also participate. Yet another could be the choice of programming language. In most cases C++ is standard but some offer various flavours of Python etc.
Here is the Arduino 101: https://docs.arduino.cc/retired/boards/arduino-101-619
I would seriously consider adding a wall wart to power the arduino, the nine volt battery is a bad choice, expensive and will not last long when running the Arduino. We see several times a month directly related to using a 9V battery which is solved when going to a power supply.
It is my understanding but not confirmed is the 101 is being obsoleted. Since it is a beginner course consider the basic UNO.
