Powering the Board
3.3.1
Power Supply
The board supports supply voltages from 13.8V (6.9V per Atmel ATA6870) to 60V. However, to run the board on voltages
below 24V the ZDiode D3 needs to be replaced with a jumper to supply the Atmel
®
ATmega32HVB with sufficient voltage. If
the jumper is mounted, the stack voltage should not exceed 48V! The Atmel ATmega32HVB supports operating voltage from
4V to 24V.
3.3.2
Emulating Cells
Battery cells can be emulated by connecting a voltage divider to the specified clamps.
Section 3.1.1 “Installing the Hardware”
describes how to connect cells. The voltage limits for this setup are the same as for real batteries.
