Re: Safety Concern: P-MOSFET Orientation in Power Path on Challenger LoRa Board

Anton,

I will investigate to see what could be happening. In the mean time i pushed the long overdue 0.2 version of the schematic to the repo.

Re: Safety Concern: P-MOSFET Orientation in Power Path on Challenger LoRa Board

Hi Anton, Thanks for getting in touch with us. This is a remnant from the 0.1 schematics which still seem to be available on our gitlab repo. This was caught early during the review process and never made it into production. The products that we are selling have the mosfet correctly oriented. We wil...

Re: Challenger RP2040 LoRa (868MHz) SPI TFT Screen

Hello Peter,

You still have access to SPI0 through the Challenger connectors where you can attach your display. I2C is also accessible so you should have no problems with either peripheral.

Re: Opendec02 V2.0 decoders not consistent

Hi, I have not been able to reproduce this on our Märklin test track. Can you share exacty how you have connected the decoder to the loco, including lamps and any other accessories that you have. I do not have a DCC-EX command station yet so tests are made with a Märkling CS3. I will try to get hold...

Re: ESP Hosted SPI based firmware now available

Hi, no not really.
We got a bit distracted when uBlox decided to cancel their modem business and we had to move new LTE boards up in the development queue.
Right now it is scheduled for this summer unfortunately.

Re: Arduino Lib Not found

Does "git clone https://github.com/PontusO/arduino-lmic.git" not work for you ?

RP2040 Connectivity board documentation update.

We've updated the "Dimensions" document to version 1.2 ( https://usercontent.one/wp/ilabs.se/wp-content/uploads/2025/01/54-00293-5_V1.2_Dimensions.pdf ) with more detailed measurements about the positions for the different connectors on the board. It should now be much easier to create a C...

Hi AlanH, It is definitely an RF issue that you are seeing here. Can you share more details about the setup that you have. What antenna are you using and how it is connected to the system as well as how it is placed in relation to the boards. A picture of your setup would help grately. The performan...

Re: RP2040 connectivity board mounting

As promised here's an updated dimensions drawing with the required copper cut out region for the WiFi antenna. This drawing is based on having the board mounted with 3mm stand offs from the base board. If the distance is increased from 3mm's the cut out region needs to be extended with the same amou...

Re: RP2040 connectivity board mounting

Hi, Thank you for the picture that clears it up a little bit. As a general rule there should not be any ground plane below the WiFi antenna area but I realize that this is not something we have documented. I will make sure to fix that during the day and reply here. But having said that, I have tried...
