DTU / AHOY housing with adapter board (socketed components)

Hey guys, I would like to introduce you to my latest OpenDTU case for the ESP32 Dev Kit C V4.

In this slightly larger version of my well-known case https://cults3d.com/:1701918, the adapter board (new version) is equipped with low-profile socket strips (max. 7mm socket height) so that the ESP32 board and the antenna module can simply be plugged in. Soldering the sockets is much easier than soldering the components directly, as the order no longer plays a role and later repairs (e.g. defective antenna module) are easy to carry out.

If a 0.96 inch display is also used, a four-pole pin header is also fitted so that the display can be easily connected using Dupont jumper cables.

To secure the display in the lid, the OLED display is placed over the pins in the display lid and these pins are then lightly melted with a soldering iron so that the display is firmly seated in the lid.

The housing (currently) comes in 2 different versions.

One version is suitable for the CTM2300A antenna module linked below and the other version is suitable for the NRF24L01+ antenna module with the attached connector for the rod antenna, also linked below.

A third version for the NRF24L01+ module with the straight antenna connection will follow soon.

Features:

• Specially designed for the ESP32 Dev Kit C V4

• The components are simply inserted on an adapter board, which is equipped with socket strips of max. 7mm height.

• Two different basic designs for different antenna modules

• Two alternative housing covers: a closed cover and a cover for the installation of a 0.96 inch OLED display.

The two variants for the different antenna modules:

• OpenDTU housing version for NRF24L01+(version with attached antenna socket)

• OpenDTU housing version for CMT2300A (from blinkyparts)
