Hi! I'm considering the use of e-paper displays in my IoT project for low-power applications. What are the notable e-paper display modules available, and are there any specific microcontrollers compatible with these displays that you would recommend?

This man is a champ! Have a look at https://hackaday.io/project/11537-nekocal-an-e-ink-calendar
Used here is ED060SC4 800x600 Eink display. Some of the other projects:
https://www.zephray.me/projects/

NekoCal - an E-Ink Calendar

A simple calendar made with e-ink display and stm32 microcontroller. Can display date&time and a background image. Images are stored in the SD card. The ultra-low power consumption and always on display make it perfect for basic information display purpose. Next step would be trying to use an ESP-32 to replace the STM32F4 make it possible to gra...

Hey @everyone!
We're about to start this week's Office Hours! The topic? Going from Maker to Pro: To Arduino or not to Arduino? See the link above!

Is there a reason you need cellular? Can you use subGHz instead?

How much data are we talking? Small control and occasional sensor updates, or high bandwidth data?

techielew•2/24/24, 12:53 AM

Hey @Software Integration devs,
We have a friend @Marvee Amasi who needs pointers on moving to RTOS-based design: Need help making the shift from bare-metal to RTOS. I missed it so am resurfacing it to the group.

Anyone have experience they can share?

AAccur4te how to setup a mqqt server in aws?

Umesh Lokhande•2/24/24, 12:12 PM

Hi @accur4te AWS IoT CoreAWS IoT Core support MQTT by default so no need to setup anything there. But if you wish to use only a Server from AWS then its possible to deploy EC2 instanceEC2 instance running Ubuntu Linux and install mosquitto brokermosquitto broker on it. Also, if you make this server public then deploy node-red and develop a custom dashboard

techielew•2/25/24, 3:09 AM

Seems like @wafa_athmani @youcef_ali @aymen ammari need to build an LPWAN system together under the guidance of @BenCos18 lol.

Not sure about @aymen ammari use case that requires cellular over LoRaWAN so like @orionrobots I’d be curious to hear about the amount of data transmitted etc before commenting further.

As for @wafa_athmani and @youcef_ali you may both want to look into ADR. It’s only good for stationary deployments but it adjusts the transmit power and data rate of the gateway/server based on the received signal strength of the device/node/endpoint so you should be able to get the power/performance optimization you’re looking for.

Umesh Lokhande•2/25/24, 5:34 AM

Hi @accur4te Yes, this is possible. The only catch is usually web hosting companies will not allow changes on the web hosting server. So better to take data from AWS IoT CoreAWS IoT Core to a custom dashboard which will be hosted on some kind of server like from AWS EC2, Digital Ocean etc. and then link to your business website. Best wishes!
