Ahoy DTU PCB Case
I looked online for suitable cases for my Ahoy DTU setup but found none. Therefore, I decided to create a custom PCB using a Wemos D1 Mini. I added support for powering it with 230 volts and included a micro USB connector. With this design, there are no more messy wires inside the casing.
Ahoy DTU is an open-source project that offers an affordable alternative to the Hoymiles converter. You can find more information about it here: https://ahoydtu.de/
Part List:
- Custom-made PCB: Download the ZIP file and place an order at https://jlcpcb.com
- Wemos D1 Mini: Purchase from https://www.amazon.com/s?k=wemos+d1+mini&crid=2VU92P26MS8U1&sprefix=wemos+%2Caps%2C236&ref=nb_sb_ss_ts-doa-p_1_6
- NRF24L01+: Available at https://www.amazon.com/s?k=nrf24l01%2B&rh=n%3A172282%2Cp_72%3A1248881011&dc&ds=v1%3AZwkScOqzc4E1mU8%2BmsScu%2B1a0Y0OWh2DRASALcTFAmE&crid=3ASP4SEBCMPT5&qid=1686300289&rnid=1248877011&sprefix=nrf24l01%2B%2Caps%2C165&ref=sr_nr_p_72_3
- 3mm LED*.
- 220-ohm resistor.
- 100uF capacitor.
- 8x M3*10 screws.
- 8x M3 inserts
- Terminal screw block*.
- Hilink 230 to 5 volt converter : https://www.amazon.com/HLK-PM01-Step-Down-Supply-Intelligent-Household/dp/B01B7GGL6C
Notes:
- The 3mm LED is optional and serves as a power indicator.
- Currently, the casing does not have a hole for the 230-volt connection. This feature is still a work in progress.
- The converter is also unnecessary if you want to power it using 5 volts from a USB source.
