What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

eDOTcore: A bit more than an Arduino Uno board

eDOT core is a versatile Arduino board with built-in precision RTC. It has been originally designed to be employed with eDOT clock and the board fits perfectly inside the eDOT enclosure, but it is also suitable for custom made portable project (solar, etc.) where a very low power consumption is preferable. It features a very essential component layout that makes the board very compact. The board does not fit USB to TTL converter but just the interface connector; an external USB to TTL converter will be required to upload the Arduino sketches. In case of very low power application the power LED can be disconnected so that the total current will be less that 500 microamperes at 5V.

The board employs Atmega 328PU chip and DS3231 for real time clock functionality and has the back-up battery on board.

The board can be supplied up to 12VDC and has two on-board low drop regulators that provides 5VDC (SPI) and 3.3VDC (I2C) for optional external board's supply. The regulators may be easily replaced to fit custom supply voltages for both the ATMEGA and the external sensors.

The double layer PCB is professionally manufactured with metallized and gold plated holes, green matte paint and silkscreen.

The I/O connectors allow to access to the full ATMEGA 328PU functionality as follow:

  • No.7 x Multipurpose digital I/O
  • No.3 x Analog inputs with 10kohms pull-down resistor
  • No.1 x LDR input (or normal analog input)
  • No.1 x IR remote controller sensor
  • No.1 x SPI port - (or 4 multipurpose digital I/O)
  • No.1 x I2C port, paralleled on two connectors - (or 2 analog inputs)
  • No.1 x ATMEGA 328PU programming port (by external USB to TTL converter)

Notes:

  • I2C lines have not the pull-up resistors. The board have been designed to accommodate external breakout boards that already fits pull-up resistor. In case no external board are required the I2C lines may be pulled-up by an external terminator.
  • For the board programming is required an external USB to TTL converter (RX,TX,DTR)

Risks and challenges

The working prototypes have been already produced and tested.All the risks are limited to the delivery times achivable by the suppliers.
