IoT WiFi Linux Computer Module BIT module BIT32CYI1 Datasheet What the heck is an IoT computer? It is a Linux computer designed specically for building connected hardware applications. It combines the tiny form factor and power-efciency of the Arduino, with the power and exibilities of the Raspberry Pi. Easy to use, even for people who are just getting started with building hardware and software. Expandable, and plugs into a variety of dock boards which support a family expansion to allow you to make cool projects. Affordable, allowing everyone to own one. With it, we want to lower the barrier of entry, and allow everyone to take the leap into hardware development. Size 1.3 inches * 0.7 inches, It is really very small.so that it can easily t into your class project or companys product. Specications MODEL: BIT32CYI1,BIT16CYI1 Field

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product. Any company of the host device which install this modular with limit modular approval should perform the test of radiated & conducted emission and spurious emission,etc. according to FCC part 15C : 15.247 and 15.209
& 15.207 ,15B Class B requirement, Only if the test result comply with FCC part 15C : 15.247 and 15.209 &
15.207 ,15B Class B requirementthen the host can be sold legally. widora.io Beijing Widora Technology Co., Ltd. BIT module Datasheet widora.io Beijing Widora Technology Co., Ltd.
