Ahoy-DTU & OpenDTU Case for Hoymiles inverter (photovoltaic)

thingiverse

This case is meant to be used to house the DIY electronics for an Ahoy-DTU or OpenDTU device which wirelessly connects to a Hoymiles photovoltaic inverter. The printed case measures roughly 4.5x5.0x2.3cm (1.8x2.0x0.9in) plus the triangular overhang at the back for improved stability when used with a relatively large external antenna. The electrically connected PCBs can be slid in side-by-side in guiding grooves of the "tray" part. The shorter PCB's groove can be filled up with some printed "spacer" (included) for a tight fit. The "hood" is just put over the electronics tray and held by some shallow grooves. I designed this case to house both a Wemos(-like) D1 Mini and a Nordic NRF24L01+(-like) PCB featuring an external antenna with an extra capacitor. The case is explicitly meant for use with short soldered wires and not for use with jumper wires to connect the electronics. Indoor use only. The goal was to keep it as small as possible. There are other great cases available from other makers fulfilling other needs.
