We need to teach the students the design rules right?
But that comes with production week group assignment.

I think this week the introductions of the test equipment right?
input week is looking deep in to DSO
14:51:06 Von Miriam an Alle:
So for the group project this week, they should be using the testing equipment on any dev board?
14:52:12 Von Noor Ahmed Raza Pirwani an Alle:
yes it make sense
14:52:13 Von Krisjanis Rijnieks an Alle:
I would split the equipment in several weeks
Oscar Diaz, andri-fab lab reykjavik:👍
14:52:23 Von Krisjanis Rijnieks an Alle:
as oscilloscope alone is a lot
Luc Hanneuse - AgriLab, andri-fab lab reykjavik:👍
14:52:29 Von Saheen Palayi an Alle:
can we switch the group assignment : )
so we get the Design rules
14:52:29 Von Krisjanis Rijnieks an Alle:
and logic analyzer is a lot
14:53:15 Von Claire Lake Mac Libraries Fab Lab an Alle:
You can design without design rules and then correct after you do the testing

looking at pwm on na osciloscope is very easy to try. plus they all have exemple/calibration signals.

# global open time
- use kicad 8, 9 still has some problems
- have 2 leds: power & debugging
debugging: run a blink program and make sure your mcu is still alive.
how to use the pin with the led? just solder pin header before or after the led.
- 2 layers
put pin through the board -> bam, 2 layers
you can connect then the two pins on the backside with a cable. there is no shame in that btw.
- suggestion: use labels. makes your design a bit easier.
- use disconnected mark in kicad if pins are not connected
- use power flags if you get errors regarding power
- you need to tell kicad where power is coming into the board
- hit p on keyboard
- pull-up & pull-down: check adrians doc
- if you do not connect the open switch directly to pin, there will be noise due to --- internal processes in the chip
- add pulldown resistor with low resastance so that noise rather goes to ground.
- how big pulldown resistors to be? (ricardo marques)
- for buttons you can use lke 5k,
- LEDs between 500 and 1k
- i2c depends on a few variables but between 900 and 5k.
- for 3.3v logic don't go over 2.5k
- [getting started with electronics](https://archive.org/details/getting-started-in-electronics/page/n5/mode/2up) pgase 6 to 41. for this weeks assignment
- make beautiful pcb, not a square. it is the design week
- check ccc talk
- make power lines of fatter thickness on a pcb
- you see it better
- signal lines you want to be thin
- thick power lines can handle more current
- some more about pullup/pulldown by ricardo marques
- if you dont use pulldown pullup, there a tristate. its not defined what voltage is on the pin. internals of mC.
- this is explained further by neil in input devices
- only use bat gnd and bat vin if usb is not used. otherwise they will conflict.
