2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 Charger click 2 3 4. Essential features Maxims DS2438 Smart Battery Monitor integrates a temperature sensor, a timer, an ADC to measure the battery voltage and current, and a current accumulator that monitors the total amount of current going into and out of the battery. Also, 40 bytes of EEPROM is available for storing important parameters about the battery (chemistry, Turn the board upside down so that Turn the board upward again. Make sure capacity etc.). Several units can work on a the bottom side is facing you upwards. to align the headers so that they are same 1-Wire bus because each DS2438 has a Place shorter pins of the header into the perpendicular to the board, then solder the unique ID. The MCP73831 has a programmable appropriate soldering pads. pins carefully. charge current from 15 to 250 mA. 1. Introduction Charger click carries both a battery charger 3. Plugging the board in controller and a battery charge monitor. The smaller chip is MCP73831, a miniature click Once you have soldered the headers your single-cell Li-Ion and Li-Polymer charge board is ready to be placed into the desired management controller. The larger IC is BOARDS mikroBUS socket. Make sure to align the cut DS2438, a smart battery monitor. The www.mikroe.com in the lower-right part of the board with the monitor communicates with the target MCU markings on the silkscreen at the mikroBUS through a 1-Wire interface. The battery socket. If all the pins are aligned connector is on top of the board.
