This Video/Audio IP device was designed with the goal to be used in the surveillance and access control market.
The main processor is a i.MX27 by Freescale and is based on an optimized embedded Linux system generated by buildroot. There are two possibilities of video acquisition: analogue video acquisition using a video code TVP5151 by Texas Instruments or digital video acquisition using an image acquisition sensor by OmniVision OV7670. For the audio system acquisition is used an electret microphone and 2 speakers of 500m Watts with the Audio Code TLV320AIC3254 and the audio amplifier TPS2012 by Texas Instruments.
Other features:
- PMIC (Power Management Integrated Circuit) TPS65051 by Texas Instruments.
- Ethernet 10/100Mbits LAN8700 by Microchip.
- RTC (Real Time Clock) M41T00S by ST Microelectronics.
- EEPROM 24AA02E48 by Microchip.
- SD Slot.
- 2 USBs.
- Expansion connectors.
This board is prepared to use with another expansion board through their expansion connectors with 10 inputs, 5 outputs with relays and 3 RS-485 ports.
I was in charge of the electronics design: schematics and PCB, as well as creating all the procedures for testing the devices in mass production.
Used technologies: Kicad and Buildroot.
