Boards

ESP8266

A very popular board due to its price and built-in wifi. It can be programmed with Arduino, Lua and C++. There are several options

• [NodeMCU v3] (http://www.aliexpress.com/item/5Pcs-lot-V3-Wireless-module-NodeMcu-4M-bytes-Lua-WIFI-Internet-of-Things-development-board-based/32469433622.html?btsid=1c01a4a2-e0a7-4607-9cc1-07bbf36e4851&ws_ab_test=searchweb201556_6%2Csearchweb201644_5_10001_10002_10005_301_10006_10003_10004_62_61%2Csearchweb201560_1%2Csearchweb1451318400_6148%2Csearchweb1451318411_6451&spm=2114.01010208.3.28.nqz0x0) - this is the newest known module
• [NodeMCU v0.9] (http://www.aliexpress.com/item/New-Wireless-Module-5x-NodeMcu-Lua-WIFI-Internet-of-Things-development-board-based-ESP8266-with-pcb/32452157536.html?spm=2114.01010208.3.345.Wyl06k&ws_ab_test=searchweb201556_6,searchweb201644_5_10001_10002_10005_301_10006_10003_10004_62_61,searchweb201560_1,searchweb1451318400_6148,searchweb1451318411_6451&btsid=6e317f20-ffaa-4a95-8987-1b3e45c05c2a) - The old model used at the first GeekyCamp lecture
• [ESP 12E naked module] (http://www.aliexpress.com/item/ESP8266-serial-WIFI-model-ESP-12-ESP12-Authenticity-Guaranteed-ESP-12E/32503234463.html?spm=2114.01010208.3.234.Ok7jTQ&ws_ab_test=searchweb201556_6,searchweb201644_5_10001_10002_10005_301_10006_10003_10004_62_61,searchweb201560_1,searchweb1451318400_6148,searchweb1451318411_6451&btsid=8efed771-3bce-4373-ae0b-14f968a1ba3f). This module is smaller and cheaper, but lacks USB to serial chip, so that an external USB to serial cable is required. It is more suitable for production (e.g. to save money and space) and for flying stuff, where weight matters a lot.

Arduino

Very popular board with a lot of accessories (shields). This is the preferred choice if you want to work with some accesories (e.g. the ZumoRobot). More info on the [official website] (https://www.arduino.cc/)

Raspberry PI

A full fledged Linux computer board. From IoT perspective, the main benefits of the board are that more complex Linux software, such as computer vision, can be used directly. Another advantage are the USB ports and the existing device drivers as well as higher level libraries, such as libnfc. There are different versions of Raspberry PI with varying capabilities. See [the Raspberry PI shop] (https://www.raspberrypi.org/products/). There are also alternative boards with similar capabilities, such as the Orange PI. The Orange PI comes in several models, of which the Plus 2 seems like the best option, due to the 2GB of RAM.

Breadboards & cables

• 830 point breadboard
• another 830 point breadboard
• Cable set for breadboard - this set includes MM (male to male), FF (female to female) and MF (male to female) cables and shall be sufficient for most of your needs.
• Additional FF cables - if you get the full set above, these are probably not needed
• Additional MM cables - these may not be needed too

• Power adapter for raspberry PI shall be powerful enough to yield 2A current. Otherwise the board might work unreliably
• LiPo charging/boost module TP4056

Tools

• Multimeter
• Pliers
• Tweezers
• Screw driver set
• Soldering iron
