Over the years, we were fortunate enough to be involved in several wireless sensor network projects in real world applications. These boards were custom boards derived from our Mini Ultra 8 MHz, Mini Ultra 8 MHz Plus and also an unreleased Mega2560 variant. On top of that, different battery chemistry, secondary power source, and different radio technology were used. Based on these iterations, we refined our design and put them forward in a new board named Mini Ultra Pro. The Mini Ultra Pro is an Arduino Zero compatible board that is ultra low power targeted at wireless sensor network (ah come on, that IoT term bore us) applications. As much as we love our ATMega328P based design, we wanted something more powerful and more peripherals than that. Running out of program flash, RAM, serial port and other resources half way through our project development is not a pleasant experience especially when time is the biggest constraint. Read more

After months of design iterations and testing, TraLog Shield v2 is finally here! We made several changes & improvement over the initial design and also managed to push the cost down. Read more

We made some small changes to the Mini Ultra 8 MHz Plus board which involves the charging circuitry on the board. Read more

We have just released our very own version of the USB-Serial board based on the new FT231XS chip. This board went through numerous revision which initially was using the older FT232RL chip. Read more

Mini Ultra 8 MHz Plus is finally out for sale. The design went through several iterations before the final version (from the full feature white board on the left of the image above to the final version on the most right). We want the cost to be optimized in order for people to be able to deploy them in bigger volume applications like for example wireless sensor network. So, we had to strip off some on of the feature available on the initial design. Having an Arduino board factor allows you to test them with available shields in the market before you eventually make a power optimized version of that shield as not many shields out there are optimized for low power applications.
