https://www.kickstarter.com/projects/11 ... w-dip-16-puChip: Arduino Zero compatible in a narrow DIP-16 package!
Specifications
CPU: 32-bit Cortex M0+ ATSAMD21-series running at 48 MHz (Arduino Zero Compatible)
FLASH: 256 kB (248 kB due to integrated bootloader).
RAM: 32 kB, zero wait states.
Powered via USB or externally (3.3V to 5V).
Integrated 500-mA boost and 1-A buck converters and automatic power switching circuitry.
Each converter can also be individually turned off, e.g. if you want to force power draw exclusively from external pins (self-powered device), or if you want to turn off an external USB device connected with a micro A cable.
When powered through the USB port, the output voltage on the power pins can be selected via software to be either 3.3V or the USB voltage (typically 5V +/- 10%).
14 I/O pins (2 of them can be used to connect an external SWD programmer/debugger) and 2 power pins (VCC and GND).
Status LED (it can be turned on/off via software using a single instruction).
Multi function push button for reset/program.
8 12-bit ADC inputs. (specification updated! Before there were only 7 ADC inputs!)
10-bit DAC output.
14 external interrupt input pins.
Up to 5 serials between SPI, I2C and UART.
I2S port for audio decoders such as UDA1334A.
13 PWM pins.
Size: 28.5 mm x 10.16 mm (1.1 “ x 0.40 “), including USB port protrusions (27.23 mm x 10.16 mm excluding USB)
4-layer board for improved noise performance.
Standards narrow-DIP footprint: 0.3” (7.62 mm) row spacing, 0.1” (2.54) pin spacing.
Pinout standard logic CMOS compatible: power and GND are on pin 16 and 8, so you can also emulate some 16 pin CMOS ICs (4000 and 74HC series)!
Low cost! (13.6€ per board for 10 pieces or 20€/board!).
