I am trying to find hardware release notes on the most recent OSPi hardware revision. Is they layout for used/unused GPIO pins the same as V1.4? I am trying to add a humidity/temp sensor and the pin array on the new hardware isn’t marked like in previous versions. Thanks.
The latest version is 1.42, which is pretty much the same with 1.4, except the relay has been replaced by a pin header to plug in an RF transmitter (to support RF stations). The used/unused GPIO pins are exactly the same as 1.4.
