Fix ESP32-CAM's terrible Wi-Fi by adding a proper antenna to it. RSSI was between -95 and -85dBm with the PCB antenna and are now around -69 with the ½-wave dipole salvaged from an old Wi-Fi router.
You'll need:
- 1x u.FL/IPX - SMA pigtail (Amazon)
- 1x 2.4GHz antenna - you can buy these, but I pulled one off an old wifi router
- 1x M3x20-ish screw if you are mounting your ESP32-CAM as shown in this post's pictures
- Drill bit to create a hole for the u.FL/IPX connector to go through.
Install process:
- Modify ESP32 to use the u.FL/IPX connector. This requires a soldering iron, but no skill to speak of - you just need to bridge two existing adjacent solder pads.
- Install the SMA bulkhead connector to the mounting bracket.
- Remove two M3 screws that affix the acrylic/PC panels of your EnXLosure.
- Add the mounting bracket and re-install screws
- Drill a hole for IPX through the frame of the Enxlosure. See pictures for reference.
- Pass IPX connector through and attach to ESP32
Filament type shouldn't matter, but I printed mine in Polymaker PETG.
