Dear all,

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 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.

And finally some pictures about it:
