Works as it should and cheap
Does exactly what it needs to do, much cheaper than other places so you can buy a spare and still save money

Works fine
Worked first time (only been running for 4 days though). I’m using it on a raspberryPI running Solar Assistant interfacing via RS485 with a Growatt SPA3000. I didn’t have an issue with the included screwdriver and appreciated the USB cable extension so there is no stress on the USB port.

have not yet tried to use it so only 4 starts at present
Arrived extremely quickly, have not yet tried to use it so only 4 starts at present. It will be used to take output from wind direction sensor to feed into raspberry pi and then to website. it didn't work, according to chatGPT after thorough testing it said it was incompatible with the wind vane

Works with no issues on RasPi3
Fairly straightforward setup on Rpi3 running Bullseye (v11) arm7l. Install the mbusd package running as a service to support the mbus protocol commonly used on RS485. Can then use a simple Python program (for example) to access devices on RS485. The mbusd can be used by other frameworks, e.g. I'm using a standalone HomeAssistant plugin (without HomeAssistant) to read from a SunSynk inverter and push results to MQTT.

Ottimo convertitore RS-485 per uso con Modscan32
Presa su Amazon Warehouse per soli €12,71, ottimo affare e funziona senza alcun problema con Modscan32 su computer Windows 11 Pro. A mia preferenza - quando inserita su una porta USB di un computer portatile - mi sembra flettere un po' troppo, tuttavia con il cavo di estensione (20cm) compreso lo si può tranquillamente distanziare e usarla senza problemi.

Adaptateur fonctionne à merveille
Relié à un système de pesage agricole, il répond parfaitement au besoin pour récupérer les informations via la liaison RS485. Merci.
