GVSDuino Features

GVSDuino-X4-CCA-01.JPG

  • GVSDuino takes two awesome boards and puts them together on one board taking the best of each and improving on both.
  • The board is a minimalist Arduino design without a USB interface so it requires an FTDI board such as the USB-to-TTL Converter board to connect up to a Host Computer.
  • The board has GVS connectors for all of the Processor I/O pins.

GVSDuino Rev X4

GVSDuino Rev X3 is a fantastic card but we wanted to change a couple of things.

  • We wanted to be able to use an ISP cable to directly program the card.
    • The pinout of the ISP connector was intended for the ATProgHead design which had a difference on the reset/D10 pin.
  • We also wanted to connect up the extra pins on the extended header.
  • We wanted to add the land-boards.com web address onto the card.

Headers/Connectors (Revision X4 board)

Digital D0-D13 GVS Headers

The Digital GVS D0-D13 headers surround the Microprocessor. The square pins are pin 1. The Microprocessor I/O connections on the headers are:

Pin Function
1 GND
2 VCC
3 Signal

Analog AD0-AD5 GVS Headers

The Analog GVS AD0-AD5 headers surround the Microprocessor. The square pins are pin 1. The Microprocessor I/O connections on the headers are:

Pin Function
1 GND
2 APS Jumper selection
3 Signal

J2 - DC Power Connector

2.1mm connector. Center connection is Plus (+) and outside is Ground (-).

J3 - In System Programming (ISP)/ATProgHead Connector

This connector allows an ATProgHead to be used with the GVSDuino. The ATProgHead is used to program Arduino Chips and Arduino cards which have ISP Connectors.

Pin Function Arduino ISP Function
1 D12 MISO
2 VCC VCC
3 D13 SCK
4 D11 MOSI
5 RESET* (IN) RESET*
6 GND GND
7 D10 RESET* (Out)
8 D7 Prog LED
9 D6 N/R
10 D8 Error LED
11 D6 N/R
12 D9 Heartbeat LED

J4 - FTDI Connector/Header

Pin Description
1 GND
2 CTS (In)
3 VCC
4 TX (Out)
5 RX (In)
6 DTR (Out)

Analog Power Selection Header

Connection Function
1-2 Power Analog pins from +5V
2-3 Power Analog header pins from Processor AREF

Board Power Selection Header

Connection Function
1-2 Power board from J2 connector
2-3 Power board from FTDI

Board Dimensions

The board size is 49mm x 49mm.

The mounting holes are sized to support 4-40 or M3 screws.

Past Revisions

GVSDuino Rev X4

  • ISP connector didn't work
    • Suspect that the RESET line on the ISP connector goes to the wrong side of the reset capacitor
    • Cut trace ARDRES U1-5 and U1-6 on rear of board
    • Add wire U1-1 to J3-5 (signal is new RESET line)
    • Rework worked
