- 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:
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:
|2||APS Jumper selection|
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|
J4 - FTDI Connector/Header
Analog Power Selection Header
|1-2||Power Analog pins from +5V|
|2-3||Power Analog header pins from Processor AREF|
Board Power Selection Header
|1-2||Power board from J2 connector|
|2-3||Power board from FTDI|
The board size is 49mm x 49mm.
The mounting holes are sized to support 4-40 or M3 screws.
3D Printed Open Frame
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
