@gohan said in 💬 Easy/Newbie PCB for MySensors:

Thanks @gohan for the feedback. Can I have the link to your solar project!

@gohan @sundberg84
This is my setup. my battery reading is a constant 2.75v, this is not true the multi meter says ~4v

Thanks @sundberg84 and @gohan

I have used made the board for 3.3v set up as per the instruction. I have usd the output from tp4056 into the Battery connector of the board I have a step board from https://www.aliexpress.com/item/New-Electric-Unit-1-PC-NEW-DC-0-8-3-3V-to-DC-3-3V-StepUP/32724361266.html According to the specification given in the same link it is supposed to stabilize to 3.3v above 3v but the sensor reports something else back to the gateway.

I do not have an electronics background. I wend through the pdf files and order the parts and looks like I got the wrong resistor and capacitor or wrong part. Looks like I have to wait for an expert to comment let me know which resistor/capacitor goes where what part size. I would love to hear from someone ;)

IS it possible to use TP4056 (https://www.aliexpress.com/item/5-pcs-Micro-USB-5V-1A-18650-TP4056-Lithium-Battery-Charger-Module-Charging-Board-With-Protection/32728720869.html?spm=a2g0s.9042311.0.0.A0lkC7) this instead of using the step up booster?
Thanks!!

@Miroslav-Kadaně Thanks!!

@gohan I have a lot c version with me :)

@llegoff nice board!!! I think 🤔 I am going to build this. However just wondering if this will support rfm69hcw?
Thanks

@NeverDie Not sure if you are referring to me?

Does any one have links to dirty pcb or OSH Park? Thanks a lot

@Koresh Might be a dumb question I am planning to work on this board, where do I find the complete part list.

@petewill Thanks Pete!!! .. I shall give it a try.

Can't wait to try this baby!!!!

@Koresh waiting for the final PCB design + BOM so I can go shop :)

@doug Can't wait for you to release the BOM

@Ed1500 @gohan Thanks. I am trying to create an ehternet gateway so I can do OTAs.

@Ed1500 Thanks for you feedback. I have switched over to using W5100. However I have noticed that for some reason I am missing a data which is sent over nrf24. The gaps in the data are random and I can't seem to figure out why this is happening. BTW I am using domoticz on a pi to get the data. Initially I was using mysensor over usb to get the data and used to work fine. In order to get the update OTA I am trying to switch to ethernet Gateway and does not seem to work :(

I am not sure where I went wrong the below code hangs half way through. I am using ENC28J60
