Job description

I am looking for a person to design a PCB board. Ultimately the board will be a connector between the following components:

1. Raspberry Pi CM4

2. mPCIE SIM7600e (or similar)

3. connectors (description below)

G-Sensor (preferably on I2C bus) 5.


The board must be designed so that it can be placed in RS 195-1525 (https://docs.rs-online.com/3133/A700000006685444.pdf) aluminium case.

All kinds of fixings, power sockets, HDMI, sim cards etc. must be prepared so that the connectors can be led out of the enclosure.


1. hdmi output

2 Ethernet connector

3 Sim card socket

4th Power supply 9-36V + ACC with tolerance 9-36V

Input 6xGPIO (used only as INPUT, galvanically isolated, tolerance 9-36v)

Sockets for external GPS and GSM antennas

RS-232 connector 8.

8. 2 outputs 12V (1A)

9. 1 output 20V (0,5A)

10. 1x USB

4x Analog input (tolerance 0-36v) 12.

12. power LED (shows if there is voltage behind the converter)


ACC must be designed so that a short circuit to "plus" will start the device immediately, when ACC is disconnected CM4 should take over the power supply in such a way that it is CM4 that will turn off the inverter after a certain amount of time and proper shutdown. The simplest solution would be to use GPIO, but we are open to other suggestions.


Voltage is to appear on the outputs when the device is running.


The device will be a kind of extended GPS locator used mainly in municipal vehicles (garbage trucks), so the whole design must be able to work in summer as well as winter temperatures (from -25 to 45 degrees).


Most likely we will choose JLCPCB, if it is possible please choose components that this manufacturer can solder into the board.
