Level translator for 2x3 AVR ISP.
Based on GTL2003 chip; jumper to select voltage between 3V3 onboard regulator, ISP voltage, or target board (powered independently); breakout pads for a breadboard.
Designed to be flat (headers mounted on the sides).

A new design for OpenEVSE. This is the logic/display board.
This version swaps out the previous power supply caps with new parts, since the old ones were marked as obsolete on DigiKey.
Also, MOSFET gate biasing has been added to the pilot generator secondary side. This allows us to use the same BOM part for both primary and secondary in the pilot generator, at the cost of adding two resistors back to the design. Alternatively, you can use pre-biased BJT arrays for the secondary pair and leave the extra resistors out. Both options are known to work properly, with slew rates of 1 µs or less.
