Teensy PCB Ardumower (T-Mow)

[Sascha]

This was the Schematic on Bernards PCB and the Picture from you is the new.

Ok Sascha, in this case, my PCB is like the picture you sent.

 

[Sascha]

Your PCB should be like this Schematic:

 

[Sascha]

Ok my bad, looks like I forgot to update the PCB from the schematic. Then you have to do it like on Bernard's picture with the resistors.
And I have to check again why this works for me.

 

[LaurentS]

Yes Sascha, it's like on your right pic, not the left one. This is the bottom connections on the left.

 

[LaurentS]

Ok, now I understand; no problems; is it the only difference one ?

It will be my Version1... I will reorder new ones later if more things have to be changed.

 

[Sascha]

Yes, that was the only mistake I just saw. Otherwise, everything should be ok.

 

[LaurentS]

OK, perfect now Thanks Sascha.

Test of Power PCB V1.06 is OK with ESP8266 3.3V module.
R10 and R11 i use 4.7K . D3 is not mount.

@Sascha Hello I also have to do this R10 and R11value change to 4.7K on the PCB Card ? and about R9-R10 / R8-R7, same soldering changes as for R12-R5 / R6-R13 ?

 

[Sascha]

I have not tested the powerpcb

No problem with power PCB v1.06 locate on my git repo
You need to see with @Sascha to be sure nothing has been changed.

 

[Sascha]

Nö Changes in the powerpcb.

Nö Changes in the powerpcb.

Thanks Bernard and Sascha, OK for power pcb. Received components from Reichelt today

 

[LaurentS]

Is it charging station and charger for 69€? I do not know it at all more.

Here a picture:

Hi Sascha and Bernard, just to let you know that for 69.90€ it's the charging station and the charger; already ordered.

 

[LaurentS]

Hello, working in my PCB could you let me know for what are J27 and J36 used ? which sort of ESP32 sensors ?
Are J3 and J30 Reserve ?

Have a nice Xmas time !

 

[Sascha]

Are J3 and J30 Reserve ?

Yes, for Sensors that need extra Pullups

for what are J27 and J36 used ?

I'm not sure, think Reserve for Sensors

 

[LaurentS]

Thanks Sascha

Many things to do; change 100 Resistors with 010 ones on cards, to solder the condensator, to add pinconnectors on Teensy and esp32 etc... .

Sascha, if you do a next version of Power PCB, could ot be possible to add room between J11/J12 and INA226 card ? I can't connect J11 and J12 without pushing on INA card.
Also, I had to bore larger holes for D2 and D5.
Question: the two connections on INA226 cards with seperated pins shouldn't be connected with stronger pins, with stronger holes in PCB ? (the question also is what could be used in this case... didn't find strongers from Reichelt, with the same distance between both pins).

Don't hesitate to let me know if you see something wrong !

 

[Sascha]

I have the normal pinheaders for the INA.

Bonjour Laurent et Joyeux noel.
Sur les photos je vois ceci:

Power PCB:
Q3 ne semble pas etre dans le bon sens.
J2 J3 J11 J12 il vaut mieux les souder dans l autre sense (comme vous l avez fait pour J9 et J10.)

Main PCB.
Diode D7 et D8 :
D7 sert a eviter une inversion dans le + et - du connecteur J25 ,donc si vous faites attention elle n'est pas utile. Si vous l'utilisez vous devez penser qu'il y a une chute de tension a ses bormes et donc vous devez avoir (5V a la SORTIE de D7 en reglant le DC/DC XL4015 ), soit certainement 5.2 V ou plus a J25.

D2 et R11 ne servent a rien ,il est preferable de ne pas les connecter (en effet lorsque le PCB est alimenté il y a deja une led sur l'ESP32 et sur le GY-521 qui nous assure de la presence de tension sur le PCB et cela evite de surcharger le convertissuer DC/DC du teensy).Lors des premiers tests ,j'avais un doute sur la puissance du convertisseur DC/DC du teensy qui genere le 3.3V a l'ensemble des peripherique du PCB (c'est pourquoi la presence de J29 et JP1 , mais apres les tests il n'est pas nécessaire d'avoir plus de puissance sur le 3.3V du PCB et donc J29 est inutile D8 inutile et JP1 toujours a gauche ATTENTION il n'est pas present sur votre photo)

N'oubliez pas de couper le shunt sur le teensy4.1 si vous alimentiez le PCB par J25 et avez le cable USB connecté a votre PC en meme temp.
et sutout regler le DC/DC XL4015 pour avoir 5V a la sortie de D7 avant de connecter l'ESP32,le Teensy et le GY-521.



R7 R8 R9 R10 je ne sais pas les changements que @Starsurfer78 a fait sur le schema, il faut donc verifier comment tout est relié . Avez vous le plan exact de votre PCB.

R5 R6 R12 R13 sont a adapter en fonction du type d'odometry que vous allez utiliser et vérifier le plan pour etre certain de ne jamais avoir plus de 3.3V sur une des entrées du TEENSY.
