4/29/2023 0 Comments Infineon ice driverIf its made by a proper fab company and they say they can do it then it becomes a mute point in most cases cause there via's are nearly perfectly flat. You usually avoid putting via's underneath other components especially smt parts. The board is quiet lose in via placements, the via's in some cases look closer to pads then they should be. With a proper solder mask it won't be to much of an issue unless your really sloppy at soldering, without a solder mask that will be a nightmare. Having never researched how to wire/measure a thermo couple or used that driver chip, and not really interested in researching them, I can only say it looks like they know what there doing electrically and iffy on the layout.Īs to the PCB I'd say it depends on how your having that board made. Also, I am very sorry for the low res images and for the pcb and schematics not being. P.S: I am attaching in addition to the PCB and schematic files, the datasheets and motor curves. I will be highly grateful to anyone who could spare some time to give me some pointers and suggestions on this shield. ![]() I am not so sure if the schematics and the PCB is okay in terms of electronic engineering principles, circuit design best practices and as an arduino shield. General purpose MOSFETS are used to driver the heaters. The AD8495 is used as ice point compensated thermocouple amplifier and the BTN8980TA from infineon is used as the motor driver. ![]() The schematics and PCB was designed in Eagle 6. The shield is designed to connect to 3 k-type thermocouples for temperature measurement, to control 3 x 24VDC, 50W purely resistive silicone heaters, to control a high current 24VDC, 120W worm gear motor, take power input from a 24VDC, 480W power supply and provide regulated 5V to the arduino. I thought that the experts on the arduino forum would be the best to give me some advice. I took a lot of advice from the freelancer and am not sure if this would work and therefore need some help so that i don’t waste any more money manufacturing it. I have designed with the help of a freelancer and my limited knowledge some schematics for a shield for the arduino leonardo for a project that i am working on.
