@crami25 I’ve been looking at the 4Relay Module with UIFlow as well. The main thing I’m trying to figure out is how the four relay channels are exposed in UIFlow and whether they can be controlled independently. It would also be useful to know if there are any limitations when switching multiple relays at the same time.

@Mumbles1 M5StampC5 as the first product with 7x7 matrix @ 2.54mm factor has no mechanical or pin compatibility in M5Stack ecosystem. The only thing that allows me is to use (from M5Stack) are two M5Stack proto boards such as: https://shop.m5stack.com/products/core-development-of-proto-board https://shop.m5stack.com/products/mini-proto-board-unit I expected that at least a new product line like Chain would have the 7x7 matrix 2.54mm factor in Chain Blank Proto with Chain Bridge, see the bellow screen snippet: [image: 1785142635549-573213aa-9a84-40ac-ac50-8fcad898b8ac-image.jpeg] but there is no a mechanical fit to the proto pins. The pin layout of the M5StampC5 is non-standard, even in its own ecosystem, I would understand if the non-stackable pins supported at least Atom (4x5pins), which would allow you to use everything from this extensive and supported Atom family.

A clear PCB photo from both sides would definitely help. I’d also measure the switch footprint and the button’s height, since the “M5” marking alone doesn’t seem enough to identify an exact replacement. If the original switch is still available, comparing its dimensions and pin layout with a replacement would be the safest approach.

Hello @mmattel I don't think you'll need a level shifter. DS18B20 can work with a voltage as low as 3 V according to its datasheet. The schematic would be something like below: 5 V --- LDO --- 3.3 V -+- DS18B20 (+) G | | R GND 4.7 k O | V G1 or G2 --------------+- DS18B20 (data) E GND --------------------- DS18B20 (-) I ran a quick test with such a setup and it worked fine for me. Thanks Felix

@charliehampton Unfortunately I wasn't logging the remote IP at the time because I was only expecting to see traffic from the Stick during testing. I subsequently reflashed the Stick to see if I could reproduce it, but saw nothing that time. So either it didn't originate from the Stick, or some first-run state survived the reflash in non-volatile storage. Yes, the traffic is unusual — it is clearly an attempted command-injection probe against a vulnerable router web interface. I've also tested and confirmed that my router is not forwarding traffic on port 8000, so I believe the request originated from inside my LAN.

Доброго дня всем, такая проблема, после зарядки с включенным переключателем (он заряжает батарею вроде только так), перестал включаться и реагировать на любые нажатия. Если извлечь StampS3, то при подключенном к нему экране и подключении кабеля Tipe-C он загорается и работает. значит проблема в обвязке по питанию, точно так же при поключении батареи в разьем он начинает ее коротить. Подскажите, в какую сторону копать? Какой мосфет или преобразователь DC-DC вышел из строя и как его проверить?
