We’re all familiar with the wide variety of Arduino development boards available these days, and we see project after project wired up on a Nano or an Uno. Not that there’s anything wrong with that, of course, but there comes a point where some hobbyists want to move beyond plugging wires into header sockets and build the microcontroller right into their project. That’s when one generally learns that development boards do a lot more than break the microcontroller lines out to headers, and that rolling your own design means including all that supporting circuitry.

To make that transition easier, [Sean Hodgins] has come up with a simple Arduino-compatible module that can be soldered right to a PCB. Dubbed the “HCC Mod” for the plated half-circle castellations that allows for easy soldering, the module is based on the Atmel SAMD21 microcontroller. With 16 GPIO lines, six ADCs, an onboard 3.3 V regulator, and a reset button, the module has everything needed to get started — just design a PCB with the right pad layout, solder it on, and surround it with your circuitry. Programming is done in the familiar Arduino IDE so you can get up and running quickly. [Sean] has a Kickstarter going for the modules, but he’s also releasing it as open source so you’re free to solder up your own like he does in the video below.

It’s certainly not the first dev module that can be directly soldered to a PCB, but we like the design and can see how it would simplify designs. [Sean] as shown us a lot of builds before, like this army of neural net robots, so he’ll no doubt put these modules to good use.

A new development board has been released from the Arduino – Arduino Zero:

A new development board has been released from the Arduino stable of development products. This board has been developed jointly by Atmel and Arduino and targets ‘The next generation of IoT development’.

The Zero board contains an Atmel SAMD21 microcontroller, built around the 32-bit ARM Cortex M0+ processor. The board also packs 256 KB of flash and 32 KB of SRAM. Shield connectors are Arduino R3 compatible at 3.3 V. The (EDBG) Atmel embedded software debugger is available to aid program development.

Acording to Massimo Banzi, co-founder and CEO at Arduino “The Zero board expands the Arduino family by providing increased performance to fuel creativity of the Maker community. The flexible feature set enables endless project opportunities for devices and acts as a great educational tool for learning about 32-bit application development”.
