S10 Sleeve Technical Description
SK - 9/18/2019
Introduction
This document is meant to describe the inner working of the S10 sleeve module.
Purpose
The JUMP battery pack can be inserted into the S10 sleeve, which will act as the housing
mechanism to charge the battery.
The purpose of the LED on the front of the S10 sleeve is to indicate the charge SoC status of
the JUMP pack.
The purpose of the hall effect switch which is activated by a magnet built into the latch
assembly, is to gracefully stop charging and turn off the battery before it is removed from the
sleeve.
The purpose of the two connectors are 1) accepts the output of the charger power 2) other
connector transfers signals + power to the rear holster PCBA.
Hardware
The S10 Sleeve contains two PCBA’s. The first PCB assembly (LED board) is located at the
front of the sleeve and primarily contains an LED, power and signal connectors, and hall effect
sensor – used as a switch. The second PCB assembly (Holster board) is located at the back of
S10 and is the wireless NFC link between the batteries internal BMS and the logic on the holster
board.
LED communicated via CLK, DATA, 5V and GND which comes from the holster board.
The switch sends a logic low transition when the latch is pressed. Hall sensor sends out a logic
low signal when latch is depressed (magnet over the hall sensor). Switch GPIO pin is pulled up
to 3V3 inside the holster board.
Two pin barrel jack, 2.1mm (ID) x 5.5mm (OD) is the 41V5 input of the charger at 3.6A max.
