The following tests were conducted on Rev0:
- CircuitPython APIs tested. Note that import order is important for correct hardware configuration and pin assignments.
- Range confirmed >100m on grass and tress, >250m on reflector.
- Resolution confirmed <1cm for nearby targets indoors.
- Update rate set to 1024 readings per second to allow for interleaved software functions.
- EMC - emission levels extremely low especially around 2.4GHz and all satellite bands.
- EMC - susceptibility minimal over wide range of frequencies and power levels.
- Power consumption - VGA draws significant current (48mA) so power control added to Rev1.
- With VGA power control on the average consumption is approximately 70mA at 5V.
- Operation on battery connection confirmed.
- Serial port tested (not I2C).
- Servo ports tested. Note that port D4 produces 3.3V logic but port D5 produces 5V logic.
- Initial eye safety testing done. Repeat for Rev1 to include the laser power controls.
- Confirmed laser SMPS draws 2.5mA at firing rate of 2048 shots per second.
- Confirmed APD high voltage supply draws 2.0mA at operating point.
- Lenses and optical filter characterized through functional testing.
