# UniSketch Panel Connections **3G SDI Arduino Shield**

The 3G SDI Arduino Shield imbedded in UniSketch panels is not compatible when using the UniSketch panel with a Blue Pill device. It will only function when working only via the UniSketch platform.

The Eth-GPI Link and Color Fly have 8x GPI Inputs and 8x GPI Outputs, this is different than the SDI-GPI Link.

The RCPv2 only has 1x GPI Input that is programmable, this is different than the RCP Pro.

The SDI-GPI Link has 16x GPI Inputs and 0x GPI Outputs, this is different than the Eth-GPI Link.

GND 2\. 12V 3\. 5V control signal for red tally 1 4\. 5V control signal for green tally 1 The next four are for daisy-chaining tally lamps: 5\. 5V control signal for red tally 2 6\. 5V control signal for green tally 2 7\. 5V control signal for red tally 3 8\. 5V control signal for green tally 3 Our tally lamps need 12V power in order to light up the LEDs. The control signals are 5V so whenever you apply 5V on one of the pins the corresponding LEDs will illuminate. **[![Tally Box.png](https://wiki.skaarhoj.com/uploads/images/gallery/2022-10/scaled-1680-/tally-box.png)](https://wiki.skaarhoj.com/uploads/images/gallery/2022-10/tally-box.png)**
