Component Notes for moonratII

[ForrestErickson]

Notes as we make the KiCad Schematic for moonratII

The tac switch: https://www.amazon.com/Momentary-Tactile-Through-Breadboard-Friendly/dp/B07WF76VHT/

Need a foot print. Start with Button_Switch_THT:SW_PUSH_6mm perhaps.

An OLED display https://www.aliexpress.us/item/2251832770994631.html?spm=a2g0o.cart.0.0.774338da9DELqk&mp=1&gatewayAdapt=glo2usa Check that it works with drivers for a domestically sourced OLED display.

Buzzer from Version 1. https://www.amazon.com/RuiLing-12x9-5mm-Raspberry-Electronic-Continous/dp/B07S85WRSZ/ref=sr_1_5

MOSFET https://www.infineon.com/dgdl/irf540npbf.pdf?fileId=5546d462533600a4015355e39f0d19a1&redirId=112283 THis has Vth GS of 2-4 Volts.

Temperature Sensor TMP36 https://www.arduino.cc/en/uploads/Main/TemperatureSensor.pdf

The OLED from aliexpress also seams to be the same (Module 12864) as this one at amazon:

While this part is wrong it might be a part with which to start to make a footprint for the OLED display of our choice.

@RobertLRead , Is the design asumption to have the two color OLED display with yellow on top and blue below? I have a vague recollection of seeing that on the moonrat somewhere but do not remember for certain. Image:

No it does use that but that was just what we had on hand. I have no strong design preference on the OLED as long as it can draw a small temp graph. On Sun, Jul 30, 2023 at 1:06 PM Forrest Lee Erickson < @.***> wrote:

Regarding Digikey source for Tac switch Lee got an email:

6/27/2023 10:33 AM

Hi I was able to find this one. SW798TB-ND B3F-6050 Omron Electronics Inc-EMC Div | Switches | DigiKey I hope it fits your needs. T4576700 is the technical reference for this call.

@melanielaporte

A quick review please and then I think you can close this out with a few notes about how the PCB satisfies the requirements above.

[melanielaporte]

Completed and discussed.
