OpenHardware.io

I think you can just set the I2C pins in MyBoardNRF5.h without remapping the pins in MyBoardNRF5.cpp. Look in MyBoardNRF5.h, under the Wire Interfaces section. Set SDL and SCA to 30 and 31 as appropriate for your board.

@yveaux said in 💬 Ikea Molgan Hack: @magpern the instructions on openhardware.io state that the Molgan must be battery powered while programming: Well, then I can confirm that you don't have to power the Molgan from batteries just for programming. Burning the bootloader works fine with just power from the ISP port and programming it through FTDI works fine if power comes from the FTDI. What I found wierd is that the atmega328 had power, the radio had power, it wrote debug messages to the FTDI - when powered through the FTDI, it send radio messages etc, but it just did not receive messages. Messages where not received until I supplied power to the + / - pads (battery pads). I did read the instructions on openhardware.io, but I didn't follow then to the t. :)

By the way, I'm currently using the RF Nano as a 'usb key gateway', or sorts. With the WebThings Gateway, a user just has to install the Candle manager add-on. Then they plug in the RF Nano and select that they want to upload gateway code from a menu. That's all they have to do.

@shajek Drivers for MS are on the Internet. There is a project in which the author finalized the library and launched MQTT for sim5320. Here is the link: https://www.instructables.com/id/Remote-Control-and-Photo-Surveillance-Over-MQTT/ . Only there Arduino M0 is used (for convenience of working with several interfaces of UART). And it even transfers the image from the camera through MQTT and 3G channel.

Please send me kicad files, the ones that can be downloaded, can't be opened in kicad 5, or upgrade here. Thank you

Could you please update the description with what component goes where on the pcb?

With how long max tape you test it ? I have a living room and i need control RGBW with about 16 meters.... I can use your controller ?

could you share a circuit diagram? thanks

Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: [image: 1562049826169-5e44feda-bb1e-4a93-b30a-0bc99a201ee5-image-resized.png] Do you remember the discussion about multinode? So, it will be available soon))

Sorry, only saw your message now. If still needed, I do have a few boards left.

I'm wondering what the minimum input voltage is. The description only says max. 6.5V input voltage from the battery, but does not say what the minimum is. Both the nrf24l01+ as well as the atmega328P work with 3.3V, so if I use three AA batteries, that should be fine, right? I suppose using two AA batteries is not enough?

Everything is possible :) I just added CAD files. If anyone wants to change something.

Please add the documents required by the CERN license used.

Really nice, did you buy the glass plates from there ? https://www.aliexpress.com/item/2gang-golden-small-glass-switch-panel-match-with-Bingo-Elec-frame-glass-or-aluminum-and-2gang/32393507034.html If not, can you please tell where you get them from ? Thank you !

id also second the use of 18650s

@user2684 Thanks a lot
