Arduino has announced a new line of Nano boards that will begin shipping next month. From the design, to the chips and features on the board, to the price, there’s a lot that is new here. I stopped by their booth at Maker Faire Bay Area for a look at the hardware.
Immediately noticeable is the new design for the pins on either side of the board, which has transitioned from through-hole to a castellated through-hole hybrid. The boards can be ordered with or without pin headers soldered in place. If you get them without, you can reflow these nano boards as modules on a larger PCB design. Recommended footprints are not yet available but I’m told they will be published soon.
The most basic model in this lineup is the “Nano Every”, a 5V board with the ATmega4809 at its center. This brings 48 KB of flash and 6 KB of RAM to the party, running at 20 Mhz. A really nice touch is the inclusion of power regulation that turns up to 21 V of input into the regulated 5 V for the chip, with the added bonus of sourcing up to 1 A for external components through the 5 V pin on one of the headers. For the hackers out there, you can choose to inject your unregulated power through the VIN line, or the USB header.
All of this is a really nice upgrade to the previously available Nano design, with the $9.90 price tag making it a really desirable board for your 8-bit microcontroller needs. The one critique that comes to my mind is that the pins are labeled nicely on the bottom silk screen, but I would also have liked to see thes ..
