There will be a charge of £10 if you want to build and own a sensor. Places are limited so that attendees get the time, space and guidance to learn. I have over ordered the PCB quantity so if you want to bring your own bits, ie you already have the 3.3V Pro mini Arduino (check version in link above, a newer pro mini has different pin holes) and RFM95W, you can have a PCB to use (while stocks last!).
This promises to be a great session.
I will prepare some PCB in advance so that those learning to solder for the first time aren't overly challenged by the task - making it yourself is so important!!
I look forward to seeing you on the 4th.
