Project description

Offering remote earnings for a PCB development specialist. There is a principled electrical circuit without microcontrollers, it must be upgraded for a printed circuit board. Add microcontrollers to the circuit, replace or add certain elements.

In short, the scheme is approximately as follows:
Two power sources (+12v) that will come on the control board.
Connect to the 5 consumers (load management), one of the consumers uses one of the power sources.
- Add two current sensors to the board (Voltage measurement of two specific consumers)
- Load management of two additional relays, with a separate external power line, coming additionally on the board
- Connecting three sensors on the I/O line to the board
Connecting to the board line of digital temperature sensors
- Connection to the thermistor circuit board
Microcontroller for receiving data from sensors
Modular connection of the SD driver, a separate microcontroller for managing the SD driver
A master microcontroller that communicates with other existing microcontrollers in the circuit.
USB output for connection to PC
- Ability to flash/flash all microcontrollers in the finished board.

Information about the names of the connected sensors to the control board, as well as the name of the SD driver, is available.
The power consumption and other necessary information for each consumer is available.
Use of microcontrollers atmega, attiny

It is necessary:
- Consultation.
- Development of a circuit board

In addition:
Protection against overloads in the chain
- Microthrow protection

For an experienced specialist, the scheme is quite simple, it does not take much time to develop a printed circuit board.
Programming of microcontrollers is not required.

Please indicate the price immediately, at least approximate.
