A brand-new addition to our shop is this family of Arduino-compatible boards that are self-soldered and designed for interoperability. The Motherboard is the central unit in the system, containing an ATmega328p programmed with the Arduino bootloader, as well as space for a real-time clock and battery as well as a Bluetooth serial module. The connections are all broken out to a screw-terminal header along the bottom of the board, making it easy to attach wires of almost any size or shape.
The silkscreen is a very nice touch for beginners, helping you to see exactly which pins are connected to what, and labelling all the pins on the header clearly. Power traces are bolded, making them easy to spot. Additionally, every pin on the ATmega as well as the RTC are separately broken out to 0.1″ pads on either side of the chip, making it easy to solder in headers for quick prototyping.
