II. Mother Board : Project for Honglong C.

The project has to be done only whith Eagle CAD software ([login to view URL]).

Components should be on one side of the pcb.

The purpose of this project is to design a PCB board with a Rasperry Pi 2/3 witch include the UPS Hat Board :

- board has to fit Standard DIN rail mounting enclosure

- 12v/24v power supply with surge and reverse polarity protection,

- External battery connector,

- On-board LED for battery operations status,

- File Safe Shutdown Functionality,

- On-board LEDs for power supply (24v, 12v, 5v, 3V3, battery, UPS) and serial line activity,

- Lcd connector (16x2),

- external ADC (Analog Digital Converter) connected via SPI to Raspberry Pi,

- Real time clock (RTC) with on-board lithium back-up battery,

- PWM FAN control,

- Buzzer,

- 8 Relays + leds (8-Channel Relay Module with Optocoupler H/L Level Triger 12V/5V ?, relays that can be configured as ACTIVE-HI and ACTIVE-LOW)

- I2C Eeprom

- Reset Button

- 40 pins female connector to interface to the Rasperry Pi 3,

- Power supply, connections ( serial, can bus...), digital and analog I/O on screw terminal block

- Headers connectors:

(Standard RS-232 and RS-485 interfaces to the Raspberry Pi serial line, with opto-isolator and electrostatic discharge protection)

1 x Protected RS232 Port

1 x Protected RS485 Port

1 x Protected 1-wire port

1 x Protected I2C port

1 x Protected SPI port

1x Protected CAN bus to connect additional board

- Stackable Header for breadboard

Both projects will have to be made, they cannot be dissociate.
