Atlas 🌍 أطلس
The third development board in Remal IoT’s family of development boards.
Atlas means “a book of maps”, and so, here at Remal IoT, we would like to think of Atlas as a board for anyone interested in exploring the world of IoT and embedded systems, using only one board as a foundation to learn.
The goal of Atlas🌍 (like Nabd🧡) is to allow users to feel comfortable working with hardware and writing code that interfaces with sensors. A number of components are built-in (like the SD card, accelerometer and more) to allow users to get started with no additional hardware.
Yes, the breadboarding area looks awkward. However, it serves its purpose well. All horizontal rows are connected (except the Arduino pinouts, which have their own area). This means you can easily connect and solder a lot of additional sensors and actuators and have Atlas be a powerful and all-encompassing board for your project, research, or prototype!
Additionally, any Arduino compatible shields you own will work on Atlas.
Check out the video for a quick introduction to Atlas v1 and all its features!
▶ Powered by ATMega32U4 (3.3V / 8-bit / 8MHz)
▶ Designed for rapid prototyping and testing
▶ Solderable breadboarding area!
▶ Arduino supported and Arduino shield compatible!
▶ Can be powered by USB-C (up to 3A!) or any battery via terminal screws
▶ Built-in MicroSD card slot for data logging or anything else
▶ On-board temperature and humidity sensor (GXHT30 – unused alert pin broken out)
▶ On-board accelerometer (KX023-1025 – two unused interrupt pins broken out)
▶ RGB LED
▶ Two free buttons
▶ Focused on educational use
▶ Circular design (looks cool!)
Atlas was brainstormed during a time when Khalid had no access to a PC. So, he sketched out the initial drafts and schematics in a notebook he had with him.
Some ideas made it, others were reworked, and some were dropped. Design is an iterative process. The best way to validate hardware is to build and use it. That is how you really get a feel for it. Have a look (at the terrible handwriting and sketches🥴) here:
