BOM #1

Open MasahiroMorsihita opened 3 years ago

MasahiroMorsihita commented 3 years ago

Since I have no knowledge of electronics at all, I asked a vendor to fabricate and assemble the PCB, but I couldn't get them to make it because the BOM was incomplete. I need the model numbers of each component, please tell me the model numbers of CON1 and 100R which are not listed. Also, there are two 100Rs in the list, is this a mistake?

Hello,

Thanks for letting us know - let me take a look this weekend and get back to you on that!

Best, -Miranda

Thank you. I'm really looking forward to incorporating OptoGenie into my slice patch experiments.

hello, sorry for the delay, we will definitely get back to you with full details on this, however my colleague Omid Siddiqui is on holiday until next week so we might contact you at the end of next week instead (I wouldn't want to try and answer this without him as he's the engineering expert!). Really excited you'll be making an OptoGenie. Thanks, -Miranda

Please find our suggestion below:

Each PCB manufacturer has different components in stock and only requires the foot print of the resistors and capacitors. The model number for the 'non standard' components are included in the bill of materials (such as the mosfet). CON1 is exposed copper pads that wires are soldered onto to supply power, ground and the pwm signal. CON1 is not a physical component. Lastly, regarding the 100 Ohm resistor (the final item of the BOM) is the potentiometer and is not fitted to the PCB board. For instance, you can buy a potentiometer (i.e.: https://uk.rs-online.com/web/p/potentiometers/8427078/ ) and solder it onto the board using wires on to the appropriate contact pad on the board. These instructions are included in the BOM file itself.
