About this 3D model
Below, translated into English by DeepL Housing for the Ahoy DTU / Open DTU with Waveshare 1.54 Inch E-Paper Display and External Antenna The Ahoy-DTU / Open-DTU is suitable for connecting the Hoymiles PV inverters of the HM series to the WLAN. There is a cutout in the lid for the Waveshare 1.54 Inch E-Paper Display. You just need to place it on it and drill into the supports with a soldering iron. Furthermore, I designed a PCB in Kicad that fits exactly into the housing. I will also provide the Gerber files. I would like to thank the Ahoy team for the ingenious implementation of the software. https://github.com/lumapu/ahoy https://ahoydtu.de/web_install/ Parts List: 1x ESP32 (I used this one: AZDelivery 3 x ESP32 NodeMCU Module) 1x NRF24L01+ PA + LNA (the plus after NRF24L01 is important) 1x extension SMA male to SMA female 10cm 1x Waveshare 1.54 Inch E-Paper Display 1x ELKO 100 μF 1x PCB (unfortunately, I don't have any left.
