I was finally able to test this on a pro lab with full 20A throughput. The small Fan started moving at ca 10A, but was still silent at 20A. We shorted and let the module take a bit of beating with no effect – it continued to behave. This turns out to be a very…
I had a few requests for these breakout boards earlier, so a few of them are on www.basicpi.com for sale at cost price. More of the boards will become available later – if you want to dive in early just watch out for proto-type offers or send me an email janvb@basicpi.org
I purchased this for < 12.- USD and tried it as a driver stage for DPS5020. It works fine. It is small and perfect for a 0-35V / 0-6A “bread & butter” lab PSU. The DPS5020 have a cut-off setting that I set to 6A. It cut’s the PSU if you by mistake allow more…
The interface on the UART is Modbus RTU. I managed to translate the document from Chinese to English yesterday, so it is uploaded on the download page. Running the top-side app was straight forward on Windows 10. I had a bit of issues with antivirus installing it, so had to switch that off. The graphs…
The diagram above show the minimum needed for any mains PSU. We need a On/Off switch and a fuse. This can be purchased as a single unit. The 2nd is the PSU itself that is available in numbers on the net in nice modules. A 12V/10A module cost < 10.- USD and they can be…
I received a DPS5020 module yesterday, well packed. This is the 0-50V/0-20A Lab PSU module I mentioned earlier. Assembling and switching this on was straight forward, and using it was a very positive surprise. I was initially concerned about it’s HMI, but I am actually impressed by the cleverness of this design. This first picture…
This is the test suit for Smart SPI. This is an old pic, but I will upload a newer one showing RPI mounted behind the 32xServo and how we access SWD & Raspberry PI for development. The mechanics of thos robot is dodgy, but it is a very good and fun test kit. I also…
I need a specialized SPI driver to support the Smart SPI concept. The block diagram above show the logical view with device to device communication, while the diagram below show the physical design. Just to remind everyone – in the logical concept we communicate device to device. In the physical this is done by a…
I have already talked about using this module as key for a home automation central. I am going to look into a few extensions (or additional module). A normal wireless have a range on ca 100m, but dealing with home automation you could use 1Km range – solutions for that exist. Another change is the…
