This Camera Module is based on a PhotoGraphy DSP embeded,have 3 resulations ,captura VGA(640×480),Capture QVGA(320×240)
capture QQVGA(160×120),uart baud rate fixed 115200.n.8.1
this module can direct controlled by a MCU through a uart interface(TX,RX),or can controlled by a PC through a RS232 port.
when power on ,user can send a serial sample command to this unit,Start Capture,GetCapture Data,and then the module can send you a compressed .jpg data to your host(MCU or PC),then you can save the data to a jpeg file on your pc,or review the image by your embeded mcu.
this voice recorder based on a Arm7 TDMI processor,it receives command from uart/RS232 interface,store voice in a SD Card based on G711 A-Law encoder.
user can send start record command to this recorder,and then recorder will work, generate a *.wav file in SD acrd,and record the voice from a expend Micphone and save the data to wav file
user can send stop record command to unit,and unit will stop work.if user want get the data in sd card fom a far distance,user can send trans data to host command,unit will send recorded file to the host through a 10meters length RS232 Cable.
this unit is very cool when you want to monitor a place.in fact this unit has worked well
in bus for driver-monitor,police or consol can conduct when bus have accident
