Table 2: Helike 1.0 UA-E3010 supplies and compatible products
1)
The copper lines of VCC_36V0 are designed for a current rating of 2 A. One Dione Maxi UY-R3020 sound strip
—
in
conjunction with an Amalthea 2.0 UA-R3020 amplifier, has a maximum current consumption of 275 mA (20 kHz). Providing
that the power supply can source sufficient current, up to seven Dione Maxi UY-R3020 sound strips can be attached to the
outputs.
2)
The copper lines of VCC_5V0_EXTERNAL are designed for a current rating of 10 A. Dione Mini UY-R3010 has a maximum
current consumption of 900 mA (per segment, 20 kHz). Since the power supply can source sufficient current, up to ten
Dione Mini UY-R3010 segments can be attached to the outputs. In a typical use case, the current drawn by one
Dione Mini UY-R3010 segment should not exceed 21 mA.
3)
A Carme speaker box (Carme 3.0 UJ-R1030 or Carme Kit Ganymede UJ-E1040G00 speaker box) has a maximum current
consumption of 180 mA (20 kHz). Since the power supply can source sufficient current, up to eight speaker boxes can be
attached to the Helike 1.0 UA-E3010 outputs (four per amplifier).
4)
Up to four Danube 5.0 UAM-R2050 audio modules can be connected to Helike 1.0 UA-E3010.
For high current applications (>2 A on VCC_5V0_External and >2.5 A on VCC_36V) replace the respective
coaxial connectors with screw terminals. The respective THT holes are in place underneath the barrel
connectors. TE Connectivity PN 282836-1 are recommended.
5.1.
USB SUPPLY
To supply the Helike 1.0 UA-E3010 PCB via the built-in USB-C connector, set a jumper to location JP1.
Ensure that no jumper is set at JP2, JP3, or JP4.
The Helike 1.0 UA-E3010 PCB is configured as USB slave device with a current draw of up to 3 A. When
using the USB supply scheme, ensure that the host device (e.g., a computer, a phone or a power bank) can
supply the required current.
5.2.
EXTERNAL 36 V SUPPLY
The Helike 1.0 UA-E3010 PCB can be supplied externally with a voltage of 36 V via the barrel
connector J2. JP2 needs to be set to select this supply. An onboard DCDC converter is used to provide
suitable voltages to the microcontroller and peripherals.
The 36 V external supply is intended for use in conjunction with the Dione Maxi UY-R3020 output device.
The necessary Amalthea 2.0 UA-R3020 amplifier can then be directly supplied with power via the Dione
Maxi UY-R3020 output connector (J16).
