Hardware Revision V6
This release marks the completion of the v6 board. It uses a new chip for power generation, the TPS65185, which should improve reliability and makes a few things easier from the user's perspective. For example, the VCOM voltage can now be set via software.
Through the use of a GPIO expander chip, 8 expanded GPIOs are available on v6, which can be accessed though the epd_board_specific.h
header.
NOTE this board version as an issue when running from battery (see #126). Please use the 6.1 release!
