21 pin Stay Alive

This blog covers wiring a stay alive to a 21 pin TCS decoder but is applicable to all decoder conforming to the 21 pin standard

TCS do not recommend soldering onto the decoder

Using the attached image solder the black [earth pin 20] and blue [positive pin 16] onto the pin of the adaptor board. When finished ensure that no balls or solder bridges are present as the SD card slot resets are close to these pins.

If the 12 volt comes into compact with the blue pin comes into contact with the SD card slot will send 12V to ground and will cause arcing/sparking that will destroy the decoder.

Use of Kapton tape across the pads is recommended.

Note: Do not use additional KeepAlive devices in parallel with the TCS motherboard.
