💬 Easy/Newbie PCB for MySensors
-
I have now updated this to Revision 9!
- Bigger mounting holes 2.5mm
- IRQ Jumper from Radio. This makes this trace disabled and D2 can be used for interupts unless jumper is connected.
- BAT and REG jumpers changed positions for better tracing.
- MysX 2,6
- Text on voltage regulater (Vout/Vin/Gnd)
- Bug with G on CAP now on the right side.
- GND and VCC swapped - so you could use a 2 pin block for GND/RAW as well.
- Capacitor to filter the booster output more (optional)
Please wait for PCB house to update to new gerber files before ordering (It should say M.Rev 5 (Manufacturer rev 5) for lastest revision when selecting PCB house)
I have not yet tested this rev... but no major changes so it should be pretty safe.
If you want to be 100% sure, download and order Rev 8.Controller: Proxmox VM - Home Assistant

Wait, what?
Missed this. I am using v8 boards. Cant seem to figure out how to search individual threads and 247 posts is a bit much to go through tonight. Will get the DMM out and try to figure it out, but what cap is labelled wrong?
Thanks,

@sundberg84 cheers, no problem on my boards, multimeter confirms this...

Hey I recently got a batch of ten pro 3.3v pro minis from ebay, I removed vreg + LED on two of them and they no longer work... Well, I cant upload. I have done this low power mod heaps of times, the boards are different from ones Ive seen before, has anyone here had this problem? Or am I just a problem magnet? Have yet to solder programming headers on a non modified board to see if its a bad batch... Maybe main power is routed through the vreg or LED regardless or something? I dont have the eyesight or mag abilities to play around...

@Matt - I have killed some when i tried to remove them led/reg with a knife (ie cutting). So i began desoldering them which workes nice. I have killed one because of a short circuit and one because i damaged the pad.
Could be as you say another routing if its a new clone. Removing the led/resisotor led to being with should not affect this as it most likely only goes to ground.

Thanks for your reply. Given I've done six or seven to date without issue I am somewhat skeptical that I have borked two in a row. I use a fine tip hakko iron, solder sucker, wick + a tiny wee flathead screwdriver for the butchery.
Maybe its time I invested in a magnifying glass heh.
Is it necessary to remove the vreg as I would think its not doing anything anyway as we are powering via VCC rather than raw? -

Yeah it is a bit. As I said, may yet be a bad batch, too busy with other things right now to test a third one.
Mind you, just found this and as I suspected, there appears to be no point in removing the regulator if we are powering directly via vcc. -

Did you try to use side pins for Vcc/Gnd connections from usb-ttl adapter? It is known for some clones that Vcc/Gnd pins on programming header do not work after regulator and led are removed and side pins must be used for uploading sketch...

Had further problems with intermittent sends. Sometimes on initial presentation it only sends the sketch name and not version number. Also sends are infrequent up to six hours apart. When it does send it often only sends one child_id when there are three to send.
Previously I thought this was most likely an issue with a noisy boost converter. However I just tried replacing the 4.7uf cap on the radio with a 47uf one. Problem solved!

Matt@Matt - Nice to hear problem solved! Its again the sensitive radio and the booster might be the cause since changing the cap worked.
One trick is also to add a delay(10) between the presentations if possible. Sometimes the radio cant keep up or something... -
Gah! I ordered through the https://www.openhardware.io/order/4/PCB10X link from Itead but got the rev8 boards. Thought the "I always update the gerber files for sale" meant it was safe to order...
-
@Efflon did the order say version m5 when you ordered? Which date did you place the order?
@mfalkvidd I ordered January 2 and can't remember what version was stated. I'm quite sure I picked Itead because it had a higher version numer (and a slightly higher price), honestly don't remember. All I know is that I didn't read this thread but rather just browsed through the page and clicked order. Afterwards I realized it wasn't clear if it was the 5V or 3.3V version but the order said 5x5cm. I also missed to choose color but "grönt är skönt".
Guess what confused me most was the statement "It may say another rev. at the orderpage but this is not EasyPCB rev but the rev for manufacturer." causing me to be trigger happy :smile: -

I wrote this notice just because itead was so slow updating to the right revision! I also spoke to hek about this a month ago according to my chat log. -
Sorry to hear... Checked the log. The order was for manufacturer revision 4 (which is what @sundberg84 call rev 8 ).
The system automatically increments the revision number each time an author makes a new release. Each manufacturer must set price on each revision(which in some cases may take a while if they do this manually). Until they've done that, any older revision where they've set a price is still available for purchase.
The revision is stated below the big order-button.
