Prepare: 1. VoCore 2. 18650 battery(Li) 3. Two wires 18650 battery voltage should be higher than 3.60V. Step 1: Connect the wire to VoCore. Step 2: Connect the wire to battery Step 3: It works Step 4: Wait about 30 second, you will find VoCore in your wifi AP list. Connect to it. Step 5: ssh email@example.com, password: vocore Now you are ready to use it. Note: 1. VoCore need a very stable input power, or it will fail to boot. (I found when the wifi start up, the momentary current is high, about 350mA~400mA, so if the input power do not have such ability to supply, it will reboot) 2. I use tape to make GND touch the battery negative pole, that is not a good idea, just temp solution, better to use a battery holder, and solder wire to it, to make sure it is well connected.
