Wireless headless Raspberry Pi Zero with APC220 radios

As a bit of a weekend project and as a way to (finally) use the really cool APC220 Radio Communication modules that I bought ages ago I've put together a wireless and "headless" setup for my Raspberry Pi Zero. This allows me to have a remote-controllable Pi Zero placed anywhere within 1 km (line of sight) without wires! I'm hoping to use this as a robot backpack initially, probably for the Jumping Sumo.

I won't go into technical detail as the build was simply connecting the power and TX/RX from the Pi UART to the APC220 module (I've used protoboard to make a "hat") and telling the Pi to use ttyAMA0 for the console in /boot/cmdline.txt.

If you have any specific how-to questions, let me know in the comments. In the meantime enjoy the photos :)

At the local end I am using an USB-TTL adapter and Putty to connect to the Pi.

  2. Actually, WiMax is very reliable. It is so reliable that back in 2004, in Aceh, Indonesia, it was used as the only means of communication for rescuers and aids after the 2004 Tsunami hit.electricalshop.net
