Importing to Kicad 6 shows TEENSY LC not coorectly

renaming the project to something with .pretty would allow people to directly include the repository with the kicad lib manager

The Teensy_LC symbol shows D+ and D- pads without pin numbers. The footprint shows them as pins 39 and 40.

Updating the PCB from the schematic reports:

Error: U1 pad - not found in Teensy:Teensy_LC

Error: U5 pad 45 not found in teensy:Teensy40.
Error: U5 pad 46 not found in teensy:Teensy40.

teensy 3.1 pin 50 is GND instead of 3.3V.

Hi ! Thanks for this great lib!
I noticed a problem with the teensy 3.2 symbol which does not have pin numbers for the pins under the teensy, that is the smd pins. I got a lot of esoteric errors about a pin ~ and fixed it by giving these pins numbers.

Teensy 4.0 is now available. There are many changes from previous layouts. I started peeking at the symbol and footprint but I haven't made anything yet. Anyone else working on them?

https://www.pjrc.com/teensy-4-0/

I have added the Teensy 3.6 symbol to a schematic, connected it up and then generated the netlist.

Now I read the netlist into the PCB layout too and I receive errors stating the footprints 57-62 could not be imported.

The fact that you left out the second GND and 5V Pin in the symbol of Teensy 2.0 leads to a fatal shifting of pins when using your footprint. From pin 15 on the connection will not be correct.

If you don't want do put in extra pins on your symbol for multiple power pins (which I strongly recommend, though), you have to have multiple pads of the same number. Otherwise Kicad will give you an error when importing the netlist, because the number of pads does not match the number of pins.

I just made a PCB with a Teensy 4.1 using these symbols/footprints. I've used them many times before but this is the first time I'm using the USB device pads on the underside of the Teensy. The practical use is to use pogo pins for these if the Teensy is socketed, I don't like Micro USB so I'm carrying it over to a JST connector on the PCB. The pins aren't labeled on the underside so I didn't catch it until I assembled the PCB and tested. I realized D+ and D- are backwards from the Line card that is included with the Teensy. The picture is of the bottom of the Teensy so when you flip it over the pins are swapped.

Another thing I noticed is the footprint for these holes is too small for standard pogo pins. It's like the exact size and while it's good for these to be tight, you'll damage the plated hole installing the pins.

Ive noticed the 4.1 pins have changed from Beta from production. I'll verify it but if you want i'll fork it and you can update it if you'd like?

Your README says it includes the footprints which were moved. Could you add a link to that?
I found it... just thought it would be helpful.

Importing a net file (with a teensy 2++) into the pcb editor gives the errors:

Error: Symbol U1 pad 0 not found in footprint teensy:Teensy2.0++. 
Error: Symbol U1 pad 53 not found in footprint teensy:Teensy2.0++. 
Error: Symbol U1 pad 54 not found in footprint teensy:Teensy2.0++.

On the C version of the Teensy 1.0++, pin 3 is labelled as "PC0_INT0_OC0B_SCL", but should be "PD0_INT0_OC0B_SCL".

at teensy.lib line 257

Per PJRC the pinout for Pin34 on the Teensy 3.6 should be 34_A15_RX5_CAN1RX_SDA0 vs CAN1TX:

Hi,
Thanks for your fantastic job.
However:
The said library cannot be opened, see:

Yet while opening the file with a text editor, you can see that the github page text is also contained in the file. I tried to remove the parasitics and save it as .lib file, but KiCad doesn't accept it neither.

Even worse for teensy.dcm that KiCad can't even recognize, despite the fact 5.1 is still supposed to be able to access this deprecated format, officially abandonned in version 6: https://forum.kicad.info/t/is-dcm-file-will-be-deprecated/13763/5

I found an issue in the symbol for # Teensy2.0_(C)
there are two pin c6. and no d6.

The SMD pads listed at the back of the teensy 4.1 isn't included in the library (nor the footprint). Is it possible to include it here?

Ok just re-checked and uderstood the pinout, sorry, you can delete the issue

Pins 46 (3V3) is labeled Output when I think it should be at least Power Output (or input, I'm still not clear for the Teensy which is better).

Same goes for pin 47 (GND) - all the other GNDs on the board are labeled as Power Input except this one.

Editing the symbol in my project fixed the ERC errors I was getting.

Thanks for this project! I'm new to KiCad so sorry if I'm just doing it wrong.

Are you interested in adding this to the official symbol and footprint collection? It would need some changes to the look of the symbols and perhaps footprints (as documented here: http://kicad-pcb.org/libraries/klc/) but would make it much easier for people to access them and also integrates well with other symbols/footprints provided in KiCad.

Add symbols and footprints for Teensy 3.5 and Teensy 3.6.

• Teensy 3.5 symbol
• Teensy 3.6 symbol
• Teensy 3.5 footprint
• Teensy 3.6 footprint

hi,

there are problems linking to the footprint (https://github.com/XenGi/teensy.pretty)

Error: No footprint defined for symbol "U1".
Error: Cannot add new symbol U1 due to missing footprint .

if footprint value is set to "lib:Teensy30_31_32_LC" results:

Changing footprint U1 pad 25 net from to Net-(U1-Pad25).
Error: Symbol U1 pad ~ not found in footprint lib:Teensy30_31_32_LC.

The Reset pin of the Teensy 3.1 and Teensy 3.2 can be accessed with a pogo pin connector. These 2 pogo pin locations could be added to the footprint.

• Teensy 3.1 pogo pin
• Teensy 3.2 pogo pin

Hello from Japan.
I want to add the .lib and .kicad_mod files of teensy3.5,
but I don't know how to convert your C programing language(？) to those files.
I’m so sorry trouble you, but please teach me how to do.
