HyTech Racing / circuits-2020 - History

TSAL rev3 (#79)

* Created a copy of TSAL rev 2 to make minor changes

* Changed the size of the pads, moved the resitor names to the right side of the board, and moved the traces so that the silk screen is visible

* Finished making the revisions for rev 3 of the TSAL

* Copied Rev2 schematic to connect to the rev3 board

* Made the board and schematic consistent

* Altered the silk screen so that it said rev 3 instead of rev 2

* added the new na555 timer schematic

* Added the gate resistor and made the text on the symbols layer

* Added a description to the schematic

* Changed a zener diode to a tvs diode and got rid of the LED silkscreen

* Changes in board review

This reverts commit d30a44cf333b6e75a81830c5357fabca05badc4e.

* Simplified switches, More cooling

Replaced MAX4622 with ADG1423
