Version 2.0 of the design is ready! The main update on this iteration is the integration of a microSD socket. The Wind Vane has the sensing capabilities but it didn't have a place to store the collected data.
The first board also had some misplaced signals. This meant that we had to solder some external wires to make the board work. The signals got rerouted to their corresponding terminals and should communicate with the Arduino Pro mini without any troubles.
