{"data":{"model":{"id":"454784","slug":"esp32-devkitc-case-with-wifi-antenna","name":"ESP32 DevKitC case with wifi antenna","authorship":"author","club":false,"excludeCommercialUsage":false,"price":null,"eduProject":null,"ratingAvg":"0E-10","myRating":null,"ratingCount":0,"description":"

This is a box to hold an ESP32 DevKitC board with a grid board to solder on connectors or some electronics. The board itself is meant to rest on pin headers so that it remains removable. There is a hole for an external antenna. To use that lookout for the specific version that has the Ipex connector for the antenna. The hole in the case fits then the usual RP-SMA antennas. The long hole (that's closed by putting the lid on) is meant to hold the micro USB power cable. It intentionally cannot be detached while the lid is closed. Holes for the lid and board screws are for threaded inserts (M3 x 3mm).

The case comes with a matching holder that can be fixed with two small Tesa power strips to a wall, so that the case itself remains easily detachable. Alternatively there are also four grooves for magnets (10 mm x 6 mm x 2 mm). Extra grooves underneath simplify later removal with a narrow screw driver.

The connector slot is mean to be used with a 4 pin angled header soldered to the board. I'm using this to connect to a power meter reader, both once with the holder and once with magnets. I have also uploaded an ESPHome config for the power meter with an ESP32 DevKitC.

I have added the FreeCAD file for easy remixing, e.g., for different connectors.

Print Instructions

I have used PETG, but any other material should work just as well.
