Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: AC High Voltage Parts

- Solder the 22k Ohm resistors (Red – Red - Orange) in R1 and R2

- Solder the MID400 AC detect chips in IC1 and IC2, line up the notch/dot with the marking on the board.

- Solder the 2 250V 1A fuses in position next to the resistors.

- Solder the 2 and 3 position 5mm screw terminals in the Test and Input locations.

Step 2: DC Parts

-Solder the 0.1uf Capacitor in C1

-Solder the 47uf Electrolytic capacitor in C2 (Check Polarity)

-Solder the 3.5mm Screw terminal

-Solder the 6 pin female stack header

-Solder the Power Supply Module to the board.

Step 3: Testing

- Check your work carefully

- Connect AC input GND (Green), H (Black), N (White or Red)

- Connect to AC power

- Measure and verify 12V output.

Step 4: Stacking With OpenEVSE

- Solder the remaining female stack header to the OpenEVSE (labeled D2 - D3 - D4 -5V - GND - 12V). Older Open EVSE boards      without 12V pin still require an external power wire. Boards with the 12V pin are powered through the stack.

- Cut the male stack pins to size.

- Screw the 3/4" spacers to the OpenEVSE board with the 1/4 (shorter) screws.

- Use the longer ½” screws and the appropriate non-conductive spacers to mount the stack to the enclosure or enclosure tray. DO NOT TIGHTEN METAL SCREWS DIRECTLY ONTO THE BOTTOM BOARD WITHOUT NON-CONDUCTIVE SPACERS, HIGH VOLTAGE IS PRESENT IN THE BOTTOM BOARD.

    Hallo an alle Bastler,
    ich habe eine Openevse HEX Datei, die die Ausgaben auf dem Display in deutscher Sprache ausgibt und das auch noch mit Umlaute! Es ist die Version 5.1.0.
    Zur Zeit habe ich auch noch Platinen von der Hauptplatine und der I2C Platine für dieses Projekt, die man bei ebay kaufen kann.
    Wer diese Haben möchte, bitte eine PN an mich: dietmarma@web.de
