The Crowtail- Deluxe Kit contains a large number of modules- 27pcs. And they are choosed 24 kinds of powerful modules for you to build more projects. This kit has prepared 18 lessons for you to drive those modules，like making a vibration alarm and RTC clock, in addition we also teach you how to get data from some kinds of modules.The guidebook is perfect for you to start the project you needed.
Some powerful module like A6 GPRS/GSM module and Crowtail- ESP8266 nodeMCU, they could be a leader to applications, the crowtail- A6 GPRS/GSM Module uses low-cost but efficient A6 GPRS/GSM chip with its popular features of ultra-small size, low power consumption and wide operating temperature range. Also the module is an ideal solution to provide comprehensive GSM / GPRS text messaging, voice calls and GPRS data transmission services for M2M applications like phones, auto motion, industry and PDA, personal tracking, power and environment monitoring, the Internet of things, wireless POS, smart metering and so on. Also the Crowtail- ESP8266 Node MCU, it adds six crowtail interface on the board, so you can easily to use the ESP8266 Iot board with other crowtail modules. We wired up a USB-Serial chip that can upload code. It also has auto-reset so no noodling with pins and reset button pressings. To make it easy to use for portable projects, we added a connector for 3.7V Lithium polymer batteries and built in battery charging. 
The tutorials contains step by step instructions of how to build a project, the example code and images also have been supplied,you will know how to combine modules and program it by these.
The kit does not require any soldering and is recommended for anyone with a drive to learn more about the Arduino and its programming. Compared to Crowtail- starter kit and Crowtail- advanced kit,it has a greatly improved and you will get greatly enrich of your Arduino knowledge when you conquer this kit.
