The devices below are personal projects & products in development which are designed to be used on a boat with onboard wireless networking and certain automation/monitoring systems (eg. SignalK, Openplotter, ESPHome, HomeAssistant). AEC-Q compliant (Automotive grade) components are spec'd when possible as they are more suitable for a marine environment than consumer grade components are.
Input: 12/24v(Min:6v, Max:36v)
- Output: 5v/3.5a & 3.3v/2a
for low voltage devices (Single Board Computers,
IoT devices/sensor/etc.)
12-48v Battery System, ~40-50 amps, Up to 75 volt panel array
Devices above are in various stages of active(semi-active?) development. Those mentioned below range from inital design planning to indefinitely on the backburner.
If you have an interest in any device here or need help with a project, get in touch.
