Hackable IoT Devices

In addition to well known Raspberry-pi and arduino following are some lesser known but cheaper device for DIY hacks:

  • ESP8266 (WiFi)

Cheap WiFi module providing b/g/n connectivity using few AT commands over UART interface. It costs less than $3.5 (less than INR 300 in India). Manufactured by Espressif, which also provides IoT SDK. Also this module is currently supported in Arduino IDE as well.
