How do I power the Touch Board?
The Touch Board can be powered and programmed via a 5V micro USB connection.
Additionally, it can also be powered from a 3.7V lithium polymer (LiPo) cell connected to the 2-way JST PH series connector. The power switch will switch the board on or off when powered by either power source. If power is supplied over USB whilst the LiPo cell is connected, then the charge LED will illuminate and the LiPo will charge from USB power, regardless of power switch position.
