A Raspberry Pi adaptor board for the HopeRF RFM95W and comptible modules.
v1.1 No functional changes. Board length reduced to 30mm, with some minor component rearrangements, to match the width of a Raspberry Pi Zero.
v1.2 No functional changes. Board length trimmed to allow it to be mounted immediately adjacent to another board on a standard 100 mil grid and the silkscreen modified to label the pins according to their RFM95W connections rather than their Raspberry Pi connections, these changes to allow the board to be more readily adapted to other, non-Raspberry Pi applications.
