AVR455
Please see the ATmega16HVA datasheet for how to wake the device from Power Off
mode, and thus enable programming and/or operation. The SB200 provides this
functionality automatically and manually.
The resistor (R24) connecting the PV2R and CELL+ should be removed on SB201 to
facilitate correct current measurements through the jumper position, as otherwise
some of the current may flow through the PV2R connection.
Max continuous current: +/-3A.
Max input voltage: 9V.
Table 8-1. Power consumption.
Application current consumption is dependant on the firmware, and if communications
are active as the ATmega16HVA has no hardware UART. AVR455 showed a typical
current consumption of 160uA for SB201-1 in a 1-cell application.
The schematics for SB201-1 and SB201-2 are provided in the .zip-file that can be
downloaded from

WARNING:
Frequency [MHz]

Connecting SB201-1 in a SB200 with Cell2 mounted will result in the
destruction of tracks as PV2R and PV1R is shorted through a 0 Ω resistor
(R9) on SB201-1. Make sure you use correct board with correct number of
cells.
