let introduce you my latest development, a power shield for Astroberry (Raspberry).
This board has the following HW features:
One power input
Integrated 3A 5V power supply for RPi
4 switchable (ON/OFF) (not regulated) power outputs
2 switchable (ON/OFF) or PWM controlled power outputs for dew heaters
Each output has LED feedback
Each output are protected with 4A fuse
All fuses have separate sense pin to detect if a fuse burned
Integrated GPS module with integrated antenna (but there is the possibility to connect external antenna as well)
Integrated BME280 sensor to measure temperature/humidity/pressure
Input voltage level measurement (max 20V)
Total output current measurement (max 16A, allowed 15A)
Cooling fan for RPi processor (selectable 3,3V or 5V fan power supply)
3,5mm jack connector with selectable one wire or I2C interface to connect external sensor or extension board
Box size: 105x125x35mm (WxDxH)
I have already tested every feature of the board and they working correctly.
One thing is open, to load the board with 15A and check how the temperature spread over the board, the next weeks I will perform the measurement.
But I have a big problem, I am an HW developer, I can write some easy SW, like I wrote some scripts to test the different features of the board but I fill myself no so confident to write an Indi library with that high quality how you do it guys.
So if someone is interested in this board I am looking for somebody who could make an Indi implementation. Of course, I can provide HW for SW development.
I think I would certainly be interested, I have no idea how to use the files on the github repo to order the boards, and would that still mean I would have to source all the components and solder them on myself, or is that the service a PCB supplier would do?
If it could be supplied as a kit to assemble, with no soldering required, then I would suppose we need to find out how much interest there is, as I'm sure ordering a number of prototypes instead of one at a time would work out cheaper with the economy of scale.
On Github, every file are available to modify the design and create your own variant. Or you can use the generated Gerber files, with these files you can order the PCB from any PCB manufacturer. Yes, also you have to take care of the order and solder every component.
I am working on to get price offer from manufacturers who can completely populate the board, I will post here how much would such a board cost.
That is not a bad idea, but currently, there is no space in the housing, a new housing concept would be needed, this SSD has no fixing screws that would make the fixing a little bit difficult. I can also imagine that the front- and backplate design should be changed as well in case of a new housing concept.
