[Course Design] Face Recognition Access Control System

The face recognition access control system test board based on MAIX BIT (K210)
currently comes with:

Voice broadcast function:
16 ADC matrix buttons,
a buzzer,
a pressure detection module
, a display screen,
the voice broadcast can be controlled through the serial port, and can accommodate more than 30 voice messages. ADC matrix keyboard with 0-9 and delete, confirm keys. The pressure detection module can replace other ADC modules as needed, such as temperature, flame, gas sensors, etc. The display screen can display camera information and discrimination information in real time.
The above functions have been verified in kind.
In addition, the board has a wealth of IO interfaces that can be expanded arbitrarily such as radio frequency modules, fingerprint modules, etc. The fpio function of MAIX BIT can arbitrarily register the multiplexing function of the current IO, so there is no need to refer to the data sheet and consider issues such as pin multiplexing.

Lithium battery power management circuit will be added in the future

Will integrate stm32 master control and JQ8900 voice chip into pcb

Radio frequency verification, fingerprint verification, distance sensors and life detection cameras will be added

besides?

As for why to use Arduino nano

Mainly because stm32 is too expensive

Secondly, Arduino is easy to use and quick to use.

MAIX BIT is a cost-effective face recognition processing module equipped with K210, developed using mircopython
