Hello people. This time I will give you one of my menu systems for graphic liquid crystal displays. I have made graphical menus in the past with a more project oriented approach, once-off, but I ended up spending time redoing the same functionality. This one I made it to be more reusable and it seems promising. It is difficult to […]

I have changed my mind regarding the project I had started with LoRa modules. I will use it as part of a commercial product for the company I am working for, and since this product will need certification, I decided to change and choose another module. I will leave HopeRF’s RFM9xW in favor of Microchip’s RN2483. RFMs are cheaper but […]
I understand from what I ‘ve read lately, that LoRa technology is gaining on, and in places overtakes competing solutions, in WAN deploying solutions. This is true especially in outdoors applications, but with good penetration in buildings and good and easier to achieve network stability, as below sources show, the future seems very promising. Deploying a Wide Area Network for […]
We all know Microchip, right? When i read about Microchip adopting LoRa technology last August, I was expecting something interesting, and it seems I was right. Microchip already had solutions based on almost every wireless technology known to man (MiWi -their own thing-, WiFi, Bluetooth, Bluetooth LE, ZigBee, and some more 2.4 GHz and sub-GHz modules). Not having a solution […]
Lately I was playing around with a kit I had bought from ICStation: MAX7219 Dot Matrix Module Control Display DIY kit. I liked it and bought it because it is compact, small and cheap. I got 4 pieces a couple of months ago, and soldered them the same day I got them! Other obligations took my mind off them and […]
LoRa,IoT
According to this EDN article, things are happening in the Internet of Things field. Especially interesting the part about LoRa internals unveiled. I think I should have a look at it first chance I get. EDN – Opening up the IoT data flood gates: Semtech/IBM put LoRa spec public.
I had some sample boards made. They have been ready for a few days now, but I have had no time to deal with them, I still don’t. I hope next week I will have them populated, and then the hardest part will start: I will need a lot of free time to tackle the software… To be continued… […]
I worked a bit on this project on the National Holiday of the 28th of October. I designed a simple PCB with through-hole parts. Here you can find the project files if you want to modify it with KiCAD: RFM92W If you just want to replicate it as is, here are the Gerbers I will have the PCB made soon […]
Well, I started working on the new LoRa modules I got from HopeRF, today. I decided I would make a small pcb to accommodate a module, a microcontroller and some LEDs and buttons. My EDA suite of choice is kicad once more. I made a footprint and schematic symbol for the modules. I’ll post here any progress…
