The SB201-1 and SB201-2 have a common PCB and only differ in which components
are mounted and the silk screen. They will be commonly referred to as SB201 in this
document unless differences exist.
The SB201 consist of three parts, the edge connector, the main area and the
connector and support area. The main area contains all the circuitry needed in a
battery pack design.
Figure 2-1. SB201 Block layout.
The main area contain the ATmega16HVA device, charge and discharge N-FETs,
10mΩ sense resistor, decoupling capacitors, filter capacitors/resistors for the voltage
and current ADCs and ESD protection.
The connector area contains holes for two pin headers with 2x6 and 2x2 pins, to give
access to several signals and device pins as shown in Table 2-1 and Table 2-2. Pin
headers with 2.54mm spacing or wires can be soldered in here. A connector for in-
circuit programming is mounted. Lastly the area contains cell balancing and a board
ID system, which are described in more details in the next subsections.
