Micro IoT gateway RFM12B shield update

I have created a new version of the micro Internet of Things gateway RFM12b shield since the first revision had some drawbacks. The new version has a port that allows an OLED display to be plugged on top, this creating a combined gateway+status display solution. I don’t have a spare OLED display to use, I…

Optiboot on the micro IoT gateway

The uIoT gateway shield has FTDI plug that I used mostly for serial debugging, while for programming I used a clone of the USBTiny programmer. I wanted to adapt optiboot for the uIoT gateway, as that will make it easier for the end user to upload sketches. The challenges of having a bootloader on it are a…

Testing the micro IoT gateway shield

As I ordered the wrong magjack for the uIoT gateway, I couldn’t test the Ethernet connectivity yesterday. I only could test that the Atmega328 talks to the ENC28J60 and ran a LED blink sketch. Today I decided to test out the shield I mentioned yesterday too – it has a micro SD card slot, a LED, a…

uIoT gateway project update

My uIoT gateway project has been put on hold lately, I have the PCBs ready for more than a month now, but never had the time to make one and test it. I finally put one together today, but apparently have ordered the wrong MagJack 🙁 Oh well, putting it on hold again until the…

Putting together Simon’s Micro Web Server

I have mentioned already, that I purchased Simon K.’s micro Web Server and have his permission to develop it further, see my micro IoT gateway post. I received it couple days ago but only had time to put it together today. Here is how it looks:   Putting it together is one thing, getting it…

RFM12B shield for the micro IoT gateway

As I already mentioned, I planned to have a RFM12B shield for the micro IoT gateway. Here is how it is looking, rendered in 3D, still work in progress, but the idea is clear. I wanted to keep the shield top for other expansions, like a micro SD card slot, but I am still thinking…
