Battery-free NFC lock module (single master/multi-slave)
TNLMSGen1 from Chivotech is a passive smartlock module developed for the unified management of multi-motor locks. It has a master module and multiple slave modules. The master module’s functions include communication, energy harvesting, power management, authentication and motor control, and can connect with an e-paper display. The master module controls the slave module through the data bus. The slave module only has the motor control function. Both the master module and the slave module connect with motors to control the managed locks. Just by closely touching the smartphone to the antenna of the main module, the main module and/or the slave module can drive the motors to unlock/lock through TNLMSGen1, without batteries. The user can be given the unlocking authority of each lock through the built-in flexible authority management function. An e-paper screen connected to the main module can display a variety of information that is fully customizable by the user. TNLMSGen1 is especially suitable for delivering cabinets, luggage, filing cabinets and other equipment with multiple locks, and can be easily managed through the unified management interface.
This is the TNLMSGen1 Standard version which contains the following components: the master module PCBA (internal firmware compatible with the TNlockGen2 standard API), the slave module PCBA, and the Android demo APP. The following features are included:
