DimeDuino

Yes im at it again with the Arduino family. I focus a lot on Arduino because of its popularity and how easy it is to use. This time around i give you the DimeDuino. Its a Flex PCB based which utilizes the ATMEGA328P. Using this MCU allows for the installation of the Arduino bootloader. Hence the Duino in the name. These will come pre-programmed with the bootloader. One portion of the circle is just for programming. There is a GND, VCC,RXI, TXO and DTR & RST depending on your programmer.

As soon as its available ill post it here and on Twitter.

Specs:

  • Atmega328 running at 3.3v/8MHz or 5v/16MHz
  • Power LED (Green)
  • User LED (D13– Color may vary but mainly Blue)
  • Reset Button (makes board 2.35mm tall, if removed its only 1.36mm)
  • 3.3v(AP2112K) or 5v (AP7335A) Linear step down
  • Flash 32KB (2KB is Bootloader)
  • SRAM 2KB
  • EEPROM 1KB
  • 20 I/O Pins (A6 & A7 are not used here. Input Only anyway)
    • 1 UART D0 (RX) and D1 (TX)
    • 1 SPI D10 (SS), D11 (MOSI), D12 (MISO), D13 (SCK)
    • 1 I2C A4 (SDA) and A5 (SCL)
    • 6 PWM D3, D5, D6, D9, D10, and D11
    • 14 I/O D0-D13

Here are some pictures for now 🙂
