Re: Uno Wifi Rev 4
It seems to have something to do with the reset pin. If I disconnect that, it works fine. Is the reset pin important on your shield? Thank you for the observation, it is only used to reset the CJ125 if the shield is reset but it should not have any importance in the function. I can see in the schem...

Re: Reading lambda values higher than 10
I have a diesel engine and would like to be able to read lambda values at idle and cruise, which are leaner than the arduino code is programmed to support in the lookup table. Is there a more detailed lookup table available or will this require the values to be calculated on the fly? I can't seem t...

Re: Uno Wifi Rev 4
Hi, I have found that the Lambda Shield 2 Example works on the new Uno Wifi Rev 4 board, returning the expected 20.95% result in free air. However, I can only do this by first uploading the example without the shield attached. If I try to upload any program with the shield attached I get a board no...

Re: Lambdashield 2
Is there a reason why you removed the Pin-Bypass in the new Shield? Even though you have the full pinout, most pins are in use which makes it unusable with any stacked shield. Instead Lambda Shield 2 can be used with Arduino Mega 2560 giving plenty of additional pins for expansion. You can still pu...

Re: Lambdashield 2
Hello Maxburn, Is there a detailed circuit diagram of the Lambda shield 2? Schematics is available on the product website . I don't understand e.g. why the shield uses the ICSP ports and why the shield does not output the whole pins reusable on top. Some Arduino boards only have access to SPI pins t...

Re: Car battery
Hi Christian, i plan to use the lambda shield in my old car to measure the air/fuel ratio for adjusting my carburetors. My question is now can i attach the board directly to the car battery? And is there something i have to take care of? Cheers Hello, No problem, just connect the battery to the lam...

Re: App freezes
I have reset the Adruino and updated it again, and uploaded the code again. When I connected the arduino I had a signal almost directly and it look liked it didnt froze but I need to drive my bike to say for sure. But I think the problem is solved. Great, problem solved? I got a realme 7 pro with A...

Re: Pins remaining for Serial Tranmission
Hello Arch, Pins D11 and D12 are reserved for SPI communication on any Arduino (MISO and MOSI). SPI is required for the Lambda Shield 2. You can use the standard Serial hardware interface RX (D0) and TX (D1) pins for serial communication on the Arduino Uno / Mega versions. On Arduino Mega you have 3...
