Heltec V3.1
A readily avaliable, cheap board that can get you started for arounf £20(GBP). The basic antenna is lacking so we recommend upgrading the base antenna to a Paradar 5dB indoor Whip or something similar. A basic case can be fashioned out of the packaging! A better quality case can be printed/bought.
Bender/Nibbler cases are really popular for this platform.
