Hi, Looking for a PCB/Circuit Designer who is able to review, comment on and improve the design of an electronic product. The product works on PoE with a limitation not exceeding 60W power budget at maximum operation. 1- The review should be done using a computer software (Proteus or equivalent) showing the power flow under different scenarios. Stress testing should also be checked. 2- The comme...
The work consists of checking an electronic diagram based on an Atmel atmel sam3x8e microcontroller (arduino DUE). Check the choice of components, their values and the different connections. Then check the PCB, if the rules are respected, check the differential pairs, impedences or any other point before putting the electronic board into production. The project was carried out on Easyeda (free)...
