$30-250 USD

Paid on delivery
I need a circuit designed for a Raspberry Pi that contains the following: Voltage regulator receiving +12V DC input and outputs +5V DC. The +5V DC will power a Raspberry Pi and should contain a UPS circuit using either battery power or capacitors (preferred). Upon +12V DC loss, the battery should power the Raspberry Pi for ~5 minutes and a signal should be sent to the Raspberry Pi over either an SPI or I2C interface to shutdown the Raspberry Pi. Within the same circuit, I'd also like to power an AV amplifier/distributor. The circuit should take one RCA input (Video, Left Audio, Right Audio) and have 4 outputs.

Hello, I have many years of experience in the development of electronics. I have projects for Raspberry Pi and other I can prepare all the technical documentation for mass production. Also fulfill all conditions for certification CE, FCC and ROHS compliance. PCB layout and Circuit Design (Altium or KiCad) I develop compact solutions, and use the new component base and surface mount components. I can show examples, add me to Skype - ivanchuba or email. I'm calculating the minimum cost of BOM at the time of development. Also I can make the necessary number of industrial prototypes. Best regards
